Thank you, Kristina, and good morning to everyone on the call today. Despite the numerous geopolitical and other headwinds around the globe, 2023 really was the year that our plan for United Next came together. Our thesis at this time last year was that operational constraints and other factors were leading to cost convergence, and those cost pressures, in turn, would lead to higher revenues. That is certainly true for United, as our diversified revenue streams continue to differentiate us from other airlines. Another way of saying that is that we believe that a new link between United's CASM and RASM was being solidified. While it might be hard to get either a CASM or RASM forecast exactly correct, we could have higher confidence in forecasting the relationship between the two, and therefore have higher confidence in our earnings and margin forecasts. And despite a year filled with events that we could have never predicted, that's exactly what happened in 2023. And so I'd like to thank the 100,000 United team members around the world who worked so hard to make that happen. And those same 100,000 people continue to deliver in the face of the huge impact on our employees and customers from the MAX 9 grounding. I'm proud of our Tech Ops team, who's taken the lead and has been working 18-hour days nonstop since January 6, to ensure that the MAX 9 is 100% safe before we return it to service. I'd also like to thank the FAA for their professional leadership in this situation, and also acknowledge that they, too, are also working long hours and weekends with us in an effort to ensure that we know for sure what happened so we can be confident that the remediation prevents it from ever happening again. 2023 really sets the stage for what is likely to be a repeat in 2024. United's financial performance was impressive, especially considering what analysts were expecting just one year ago. In 2023, we delivered full-year earnings per share above $10, which was within the range of our initial United Next targets of $10-$12. I want to spend some time today examining how we got there and why we think those trends will persist in 2024. One, we expected the operating environment to be challenging, driven by pilot and other hiring constraints, FAA air traffic control staff, maintenance catch-up, and supply chain issues. It turned out to be even more challenging than we thought. Two, those operating environment challenges led directly to industry capacity plans, including our own, coming down 3 points on average as carriers adapted to the new operating environment. For United, we made changes to our schedule, and we closed out the year setting operational records. The improvements in Newark, in particular, are one of the most important accomplishments that we achieved last year. Brett will share more, more details in just a moment, but the FAA waivers, right-sizing the airport and airspace to physical constraints, and allowed us to run an operation that's performing better than ever in Newark. That's been good for our business, and it's been really good for our customers. Three, but as we predicted, the challenging operating environment led to cost pressures and cost convergence in the industry. To be fair, even we at United underestimated the inflationary pressures that we would face, primarily from labor, maintenance, and supply chain issues, and that led to higher absolute CASM effects than we were forecasting. But those same cost pressures are being felt across the entire industry. And a year ago, when we talked, we believed the industry-wide cost pressures would wind up as a pass-through, much like fuel has been in the past. Four, and that is, in fact, exactly what happened. While industry cost pressures drove higher CASM at United, we offset those higher-than-expected costs with higher-than-expected revenues. Five, which leads to the final point. While difficult-to-predict events like a fuel price spike, rising conflict in the Middle East, fires in Maui, persistent inflationary pressure, so many other things that make it difficult to predict United's full-year 2023 CASM and RASM 12 months in advance. The tightening connection at United between CASM and RASM meant that we achieved our initial $10-$12 EPS range, despite those multiple headwinds around the globe. The link between RASM and CASM, combined with the success of United Next, is what made 2023 such, such a successful and important year in our history, and we expect 2024 to follow a similar path for the same reasons. This is just the new normal. The operational challenges remain. It will be years before the FAA is back to full staffing. We're still overlapping new labor agreements, which show up in our CASM, and the supply chain challenges aren't going away anytime soon. That means capacity will continue to ratchet down out of necessity, and cost convergence will continue. But revenues will adjust to the new cost reality, and you can expect United to maintain and grow EPS and margins. Two and a half years ago, we laid out our United Next growth strategy. In 2023, we demonstrated that the plan is working almost exactly as we expected, and the future is bright. There have been, and there will be more, bumps in the road, but we continue to feel confident about our ability to grow earnings and margin over the long term because of the tighter connection between United's cost and United's revenue. Looking ahead to 2024, the United Next plan is working, and no airline is better positioned to capitalize on industry and macroeconomic trends than United, and we're continuing to move aggressively to capitalize on emerging opportunities. We'll have more to share with you at our Investor Day later this spring. In the meantime, we're focused on delivering another great year for our employees, customers, and our shareholders. With that, I'll hand it over to Brett. Thank you, Scott, and good morning. As of Saturday, January 6, Boeing 737 MAX 9 aircraft has been grounded. We are currently the largest operator of the fleet type, the aircraft representing approximately 8% of our capacity in the first quarter. Our financial guidance assumes that United's 79 MAX 9 aircraft is grounded through the month of January. I echo Scott's gratitude for all United, who worked so hard therefore, travel plans were affected by the grounding of our MAX 9 fleet. I'm also extremely proud of our tech ops team, who are working carefully to ensure the safety of our MAX 9 aircraft before we start flying them again. 2023 was a year of growth and restoration, and we closed out the year with strong record-breaking operational results, carrying a record 171 million customers. The fourth quarter consolidated customer D0, A0, and misconnect rates were the best for any quarter in our history. Not only did we set company records for the quarter, but we also ran record-setting operations during our busiest time of the year over Thanksgiving and Christmas. Thanksgiving and the entire fourth quarter had the highest NPS scores in our post-pandemic history. We wrapped up the year with our lowest-ever cancel rate for the month of December. One of the largest challenges United and all airlines flying to and from New York have historically faced, more flights than the air traffic system can handle, is now being addressed, thanks to proactive intervention by the FAA. Newark, United's largest hub, has been operating with the best reliability on record since the FAA mandated that flight activity be consistent with the airspace and runway limitations of no more than 77 operations per hour this fall. For United, that meant we reduced flight activity from Newark by about 10%. Expect to continue with those cuts for the remainder of 2024. Our customers and every passenger flying from New York are now benefiting, and the cascade of delays that historically would flow across the United States from New York airspace has significantly improved. Our customer D0 from Newark, the company record 76% in Q4 of 2023. We expect this level of performance to continue as long as the FAA continues to mandate that flight operations remain at 77 or fewer operations per hour going forward. United plans to continue to upgauge our Newark flying to ensure that there is plenty of capacity available for our customers, even with fewer flights. 2023 was also a banner year for employee recruiting, hiring, and retention at United. On the heels of hiring more than 21,000 people in 2022, we hired another 16,000 aviation professionals to our airline last year. We hire the best of the best. The skill and talent of our employees played a big role in our operational performance, outperformance in the second half of the year, our record-breaking customer scores during the holidays, and our overall financial performance as an airline in 2023. We are a better, more successful airline because of our people, and I'm proud of the way we've gone about growing our team. I'm happy to announce we will be paying our eligible employees $81 million in profit sharing next month. This is 5x higher than 2022 and over 2x higher than the average of the last 10 years. Our team, the beating heart of this airline, I'm sharing these impressive results today without them. With that, I will pass it over to Andrew. Thanks, Brett. As Scott mentioned, cost pressures led to healthy revenue trends in the quarter, with stellar performance over the holidays. Total revenues in the fourth quarter increased 9.9% on a 14.7% increase in capacity. Consolidated TRASM was down 4.2%, and PRASM was down 3.3% for the quarter. Domestic demand was strong in the quarter, and PRASM results were slightly negative year-over-year, a nice improvement from the third quarter. Atlantic PRASM growth in Q4 of +3.8% was consistent with Q3 year-over-year growth of 4%. We also experienced a small but measurable demand weakness period across core Europe in Q4, triggered by the conflict in Israel, but that has now moderated. United increased Asia-Pacific flying by 82% in the quarter. PRASM was down 11.6% year-over-year. In the quarter, we increased flying to China from four weekly flights to twice daily, among many other changes. We've now fully restored our capacity to pre-COVID levels across the Pacific. Latin American unit revenues decreased by 11.6% in the quarter, pressured by record industry capacity levels and heavy fare discounting. Cargo revenues continued to adjust to their new steady state post-pandemic, post-pandemic state. For 2023, cargo revenues were $1.5 billion, 31% lower than 2022, with almost all the revenue changes due to yields, not volumes. MileagePlus - Turning to our outlook for the first quarter, we expect TRASM in Q1 to be approximately flat year-over-year, which is a nice sequential improvement versus the past few quarters. Domestic demand remains strong, with increases in business traffic volumes year-over-year, in addition to stronger pricing thus far this year, and we expect domestic year-over-year PRASM to be positive for the quarter. We see the best yield growth occurring on tickets purchased within a week of departure. Bookings and yields for Atlantic flying in early 2024 are also strong, and we expect these trends to continue into the second and third quarters. Service to Tel Aviv will resume as soon as it's safe for our customers and crew, but no sooner than February 15th. We also saw a nice step-up in London Heathrow business demand in recent weeks, which has helped in Atlantic results in Q1 to date when combined with lower United capacity to London. We remain focused on slow growth across the Atlantic for 2024. Asia-Pacific growth remains above normal as we head into Q1. We continue to absorb the incremental Asia-Pacific capacity added in 2023. We expect all of United's new Asia capacity to produce strong margin results as we head into Q2 and Q3. Latin American RASM is expected to remain negative for Q1 year-over-year, a trend that's likely to continue into Q2. FAA-imposed industry capacity limitations on New York for virtually all of 2024 and San Francisco for most of 2024 will limit capacity from either airport. We've prioritized international growth over domestic at both hubs. We're optimistic that the demand will catch up with supply in 2024 in these two United hubs that have lagged the recovery elsewhere. In summary, we expect strong unit revenue performance on domestic and Atlantic capacity in early 2024, with weaker results in Asia as we absorb 2023 growth, and in Latin America, due to record industry capacity growth levels. While we expect international RASMs will grow slower than domestic for a period, we also expect that international flying will have materially higher margins for United versus domestic in 2024, just less of a gap than in 2023. We at United have, I think, created a really very durable commercial model that has diversified our revenue streams and our network, and largely de-commoditized our product versus just about every other airline in the U.S., maybe for the exception of one. Our commercial strategies resulting in fare levels at United, adjusting not only for changes in price of fuel, but also for the cost inputs at United, allowing us to overcome the inflationary cost pressures larger than we expected in 2023. You can see this in our relative revenue performance quarter to quarter. United's unique hub system in the largest U.S. cities and the network we have built over decades from these hubs underpins our outlook and gives United access to revenues and profitable flying others simply do not have or have not been able to replicate. The United Next fleet growth in recent years has allowed us to unlock the true value in our hub system, which you can see from our results today. Unique aircraft, cabin, and capacity plans continue to be a driver of our strong revenue performance, particularly as demand for premium products remains elevated. For example, domestic premium revenue grew 13% year-over-year in Q4, over double the rate of coach, another data point validating our strategy. While we remain focused on monetizing our growing premium capacity, we also remain committed to Basic Economy. Domestic Basic Economy revenue was up nearly 20% in the fourth quarter versus last year. Correcting gauge deficits at United remains a key component of the future. We continue to believe we can add gauge to domestic flying while maintaining strong unit revenues. Since 2019, United has increased its North American gauge by 22%, while also leading in PRASM growth. For 2024, we intend to focus much of our domestic growth in our mid-con hubs in Washington Dulles, as we add significant levels of new connectivity. This connectivity change is why we have confidence in the RASMs being accretive in 2024. Diversified revenue streams across our global network remain key to our relative success as we implement our United Next plans. United's global network is a key structural advantage we will focus on in the coming years, and it differentiates us. With that, I wanted to say thanks to the entire United team and hand it over to Mike to discuss our financial results. Mike Thanks, Andrew, and thank you to the whole United team for closing out the year on a high note, both operationally and financially. I'm proud to report that in 2023, we delivered pre-tax income of $4.3 billion, a more than $3.2 billion improvement over 2022. We delivered earnings per share of $10.05, within our initial guidance range of $10-$12, and well ahead of consensus expectations of about $6 at the beginning of the year. We achieved this despite significant industry headwinds and operational constraints that led to lower capacity. For the fourth quarter, we delivered pre-tax income of $845 million and earnings per share of $2, ahead of consensus and above the high end of our guidance range. Strong operational performance, robust revenue trends, and a decrease in fuel prices supported these results. Fourth quarter CASM-ex was up 4.9%, as we did not operate flight to Tel Aviv for the full quarter. Additionally, effective with the fourth quarter, we are now classifying certain commissions that had been classified as contra-revenue as distribution expense. This has no impact on net income or cash flow. This change added 1 point to our year-on-year fourth quarter CASM-ex and increased fourth quarter year-on-year unit revenue by 0.6 points. The change will also result in an approximate 1-point headwind to year-on-year CASM-ex and an approximate 0.6-point increase in RASM through the end of the third quarter of this year. Underlying unit costs trended favorably during the quarter as our completion factor came in better than planned due to our strong operational performance. Compared to 2019, our relative performance on CASM-ex was near the top of the industry. As Scott outlined, delivering strong relative cost performance remains critical to the successful execution of United Next. We have always asserted that costs that are borne by the entire industry are passed along, and prices with a lag. Historically, this relationship has been clear with jet fuel prices. More recently, the relationship has been clear for both higher labor and higher maintenance costs as well. Notably, our unit costs in 2023 were up 17.8% versus 2019. Compared to ultra-low-cost carriers, unit costs that are expected to be up 25% on average. That more than seven point cost convergence in costs occurred simultaneous with an emerging preference for United products. The top-tier operational reliability that United provides. The result is unsurprising. Our margins have dramatically and structurally improved, and we're only in the early innings of that journey. For the first quarter of 2024, we expect a loss per share between -$0.35 and -$0.85. While our core costs remain on track, our first quarter CASM-ex faces a few headwinds. First, the cancellations of the MAX 9 flights have reduced first quarter capacity. Due to the close-in nature of these cancellations, most of our expenses are fixed, and we also incurred additional interrupted trip expenses. We expect a combination of these items will increase CASM-ex by approximately three points. Second, as we mentioned, that the contra-revenue reclassification into distribution expense is the one point headwind. Third, the impact of new labor agreements as they annualize adds an additional 3-4 points. And fourth, a higher volume of engine events and continued supply chain challenges lead to another one point of CASM Max headwind. While the first two items I mentioned are United-specific headwinds, labor and maintenance are an industry-wide issue and the primary drivers of the cost convergence that Scott described earlier. Most importantly, we're confident that the pace of inflation in our costs will continue to be favorable versus our historically lower-cost competitors. Building off of our 2023 momentum, we expect full-year 2024 earnings per share to be between $9-$11. We are encouraged by the trends we're seeing, and our United Next plan is working well. This is our guidance, but I'd be remiss if I didn't point out that our internal targets are higher. We plan to update our longer-term financial targets at our upcoming Investor Day. Looking ahead, we intend to take a different approach to guidance. As demonstrated in 2023, and just recently with the MAX grounding, we operate in a dynamic industry. With a no-excuses philosophy, we intended to take United off the detailed quarterly metrics shortly after I joined and led the investor relations team. The pandemic interrupted those plans, but now that we're past the crisis, and as we deliver on our earnings per share targets, you should expect us to remove TRASM, CASM-ex, and capacity guidance and focus on earnings per share. We've provided RASM and TRASM for the first quarter, but this is likely the last time we will do so for a quarter. We will continue to provide fulsome commentary on the trends impacting our business, and we will continue to be transparent with our views of the longer-term future for both United and the industry that we're managing this business towards. We will earn your confidence by delivering bottom-line results. Shifting gears to the fleet. In the fourth quarter, we took delivery of 20 Boeing MAX and four Airbus A321 aircraft. Looking ahead to 2024, we have a total of 107 aircraft scheduled to deliver, 31 of those being MAX 9. It is unrealistic at this time to believe all of those aircraft will deliver as currently planned. We also have 277 MAX 10 aircraft on order through the remainder of the decade and an additional 200 options for MAX 10 aircraft. We are monitoring Boeing's air progress towards certification of the MAX 10 closely. At this time, our current aircraft delivery schedule would lead to a total CapEx of approximately $9 billion in 2024. But given the MAX 9 grounding and the continued supply chain issues, there is a downward bias to our 2024 spend. We also expect a reduction in orders and deliveries from Boeing in 2025. This will require a reworking of our fleet plan, and we will share the details when that work is complete. Turning to the balance sheet. We ended the quarter with $16.1 billion in liquidity, including our undrawn revolver. Our adjusted net debt to EBITDA was 2.9x, consistent with our leverage target of less than 3x provided at the start of the year. Managing the business towards positive free cash flow will be a top priority for our team over the coming years. Our stock is deeply undervalued, trading at less than 4x earnings, despite the fact that we delivered 19.5% revenue growth and realized significant structural improvement in relative profitability in 2023. But we also understand that generating free cash flow consistently, even while we execute our United Next strategy, is an important component to increasing our valuation. 2023 marked the first full year of United Next plan. We were thrown some curveballs, but we adapted quickly and exited the year stronger than ever. It's clear that when customers are given a choice, they are choosing United. You can see it clearly in our revenue and margin performance relative to the industry. Finally, I'm happy to announce we will be hosting an Investor Day on May 1st in Chicago. We plan to provide an update on our progress with the United Next plan and introduce some of the unique United tailwinds that will drive continued margin expansion and sustainable free cash flow. I'm encouraged by our results and our relative momentum, and I'm looking forward to delivering another solid year for our employees, customers, and shareholders. With that, I will pass it over to Kristina to start the Q&A. Thanks, Mike. We will now take questions from the analyst community. Please limit yourself to one question, and if needed, one follow-up question. Steven, please describe the procedure to ask the question. Thank you. The question-and-answer session will be conducted electronically. If you would like to ask a question, please press pound two on your telephone keypad to be entered in the question queue. Please hold for a moment while we assemble our queue. All right, we will go to the first caller in queue, Ravi Shanker from Morgan Stanley. Ravi, your line is unmuted. Thanks. Morning, everyone. So maybe, Scott, you said at the start that you saw pressure on your 2023 capacity, and I think you kind of went through your order book and said there's downward pressure there expected as well. Does this want to make you look at the long-term United Next growth plans and kind of what can be practically achieved in the coming years? Is that something you can expect to do in the Investor Day? Hey, Ravi, this is Mike. Look, the reality is that with the MAX grounding, this is the kind of straw that broke the camel's back with believing that the MAX 10 will deliver on the schedule we had hoped for. So we're working through an alternate plan. We do expect our growth rate to slow in coming years. The United Next plan is firmly on track. It will take a little longer to get there. And we're working on alternate plans to see how much higher we can elevate the growth with the MAX 10 out. Now, we're still counting on Boeing, and we're monitoring the MAX 10 closely, and we're rooting, and we'll do everything we can to help that aircraft get certified. It's a great aircraft, but we can't count on it, and so we're working on alternate plans. The details we'll share when we have them. I hope we'll have more by the first quarter conference call, and we'll certainly have a fulsome update for you by our May 1st Investor Day. Very helpful. And maybe a quick follow-up. I think you guys have said, Asia, can be, a pretty decent kind of as it comes back. I think you guys were profitable on the China routes prior to the pandemic. Correct me if I'm wrong. Do you think Asia margins can be better than before, and is that a temporary demand catch-up, or do you think, that's sustainable kind of in the new normal? Yeah, its Andrew, as we rebuilt Asia, we definitely wanted to rebuild it so it had sustainably higher margins than it did pre-pandemic, and we've gone about that, I think, very carefully. We're back to our pre-pandemic size, which is nice at this point, and China was profitable for us pre-pandemic, although it was not our highest margin client, to be fair. As we bring it all back, our goal is to make sure that the Asia Pacific entity produces margins that are similar to that across the rest of our global network, and I think that at least in 2023, Asia Pacific is well ahead. I do expect, you know, things to move around a bit, particularly as more China flights come back online. But I think we're particularly bullish about what Asia looks like, going forward. We added a lot of capacity in the quarter. We are absorbing it, and we expect, in Q2 and Q3, that capacity is gonna do very well. So very bullish about the long-term prospects in Asia, post-pandemic. All right, we'll go to the next caller in queue. Jamie Baker from JP Morgan. Your line is unmuted. Fair enough. Good morning, everybody. First one for Andrew. So you said the 20% revenue increase for basic economy. What can you tell us about the composition of that growth? Is, you know, with some percentage MileagePlus members trading down? Is some percentage, you know, stimulation of brand-new demand from scratch? Is some percentage share shift from LMAs? I guess the simpler question is, who's driving the growth? I think it's largely share shift, Jamie. You know, we, we developed Basic Economy numerous years ago now and have been refining how we sell it, how we distribute it, and that product, and it's an important product in our lineup. You know, we, we do focus a lot on premium, but we know we need to be competitive across the whole range of needs that our customers have in our hubs, and that required a competitive Basic Economy product that we could do profitably. And as we look at the data, we think the biggest change here is, as we've increased our gauge, we've been able to attract more and more market share across the board. But in particular, we've been able to attract more of it from some of the low-cost carriers out there. So we're really pleased with this development, and it's given us every indication that we should continue to push forward. As our gauge increases, we'll be able to more effectively take on that traffic, and then grow our share base even more. Okay. Thanks for that. And then for Mike, it was a couple of years ago, in fact, it might have been like almost two years to the day, that there were press reports that you were, you know, United was looking at monetizing a portion of MileagePlus, and then, you know, things subsequently went pretty quiet on that front. So a couple of questions. You know, first, is loyalty as important to United as it is to Delta? You know, Delta leans, you know, so hard into this topic on its calls. And second, any thoughts on how United or, you know, the broader industry might get investors to value this cash flow at a higher multiple? And if the answer is no, I'm happy to cede the floor. Thanks, bye. Jamie, thank you. I appreciate the question. This is something I'm very passionate about. MileagePlus is a crown jewel in the businesses we have here at United Airlines. We've made some significant progress towards growing that business. We have a new leader in Richard Nunn. We have significant projects underway around data and how we can create a better customer experience and monetize that data simultaneously. You can expect a very fulsome update on the May 1st investor day. We do have ideas on how to bring the market's attention to the value and the higher premium multiple that those earnings should trade at. We have several options, and we'll share more when we're ready to share more. But, we've discussed some of those, but some of those have been written about in the analyst reports. And if the value is not recognized in our shares, we will take action to, to highlight that value in the future, in the near future. All right, we'll go to the next caller in queue, Michael Linenberg from Deutsche Bank. Michael, your line is unmuted. Sorry, one moment, please. Michael, your line is unmuted. Oh, hey, can you guys hear me now? Yes. Oh, great. Just getting back to, I guess, Scott, on the issue with the MAX 10, at least fortunately, in the case of United, you do have a choice. You're a very large operator of the Airbus product as well as the Boeing narrow body product. As we think about the issues with supply chain and constraints across the OEM space, is there at some point where you're thinking that it's, given the size of United, that it would be prudent to consider a wide body from another OEM? You know, right now, it looks like the 787 is the future for United from a wide body perspective, but you still have that A350 order out there. Has your thinking on that changed? Thanks. Hey, Mike, thanks for the question. The A350 is an incredible aircraft. We have a significant order book for 787s right now, and we have a mix of 777 aircraft. Some are relatively older, and a sub fleet is quite young. As we look into the 2030s, the A350 is an aircraft that we are looking at. We don't have any new news to share with you today. Mm-hmm. But the timing would be that early part of the next decade. Great. And then just quick follow-up back to, you know, what Jamie brought up on Basic Economy. The 20% increase is obviously, obviously pretty significant, but last quarter, you were up 50%. And the question is, is that just a function of a more difficult comp, or did you actively pull back on inventory of Basic Economy, just given the surge that we've seen on the cost side? And back to your point about sort of, you know, trying to maintain that gap between CASM, RASM. Thanks for taking my question. Hey, its Andrew. No, we didn't pull back on it for that reason. And remember, these are year-over-year comps, so you have to consider the math of what we did last year. We're very bullish about basic. We're also very bullish about premium. And the point is we have a really great diversified revenue stream across all of our cabins as we try to de-commoditize our product. We are really hopeful that we'll continue to drive increase in volumes in basic. It seems to be having the appropriate PNL effect at United and competitive effect across the industry. So something we want to do more of, not less of, and so you should expect that. We'll go to the next caller in queue, Conor Cunningham from Melius Research. Conor, your line is unmuted. Hi, hi, everyone. Thank you. I'm a little confused on the comment between the, on the link between CASM and RASM. I would have thought that would have been the case before, so I'm just trying to understand what's changed. Is it that you're being better, like, just better at predicting outcomes, or is it really more of an industry comment that you're trying to drive home here? Thank you. It's really an industry comment. In the past, if United had, if any airline, including United, had CASM going up while others had CASM going down, the prices price to the lowest common denominator. So it's an industry comment. As industry—just like fuel. Anything that affects the whole industry is a pass-through. If it affects one airline, it's not, but if it affects all airlines, it's a pass-through. That was—we were sitting in this room a year ago, and maybe we didn't do it articulately, but that was the point we were trying to make. And that is exactly what happened, and it is what's going to happen going forward. Okay, appreciate that. And then, it was a little unclear on the prepared remarks. I'm just trying, d oes your outlook for costs include accruals for open labor contracts? And just what are the risks that you see to the cost plan in 2024? Thank you. Hey, Conor, this is Mike. We include our expectations for all labor agreements in our guidance. All right, we'll go to the next caller in queue. Catherine O'Brien from Goldman Sachs, your line is unmuted. Hey, good morning, everyone. Thanks so much for the time. I might stick with the cost side, just following on Conor quickly here. You know, versus your low single digit ex-MAX impact CASM- ex guide for the first quarter, how do we think about the puts and takes through year end versus that level of CASM- ex inflation? You know, before today, I was originally assuming, you know, growth would decelerate over the course of the year, but CASM- ex comp fees. So, you know, each quarter in my model ended up looking pretty similar on a year-over-year basis. You know, ex-MAX impact in the 1 Q, is that a fair way to think about it, or is there more lumpiness than that that I'm missing? Then, I guess, just to put a finer point on one question, does 1 Q and full year EPS include any flight attendant accrual? Thanks so much for the time. So, Katie, let me take the last question first. We include our expectations for labor agreements in our guidance, full stop. Regarding CASM trends in Q2 and three and four, you would expect the MAX headwind to go away. We do think we're getting closer to seeing that aircraft fly again. You would see some United specific tailwinds, with some gauge increase. Although with slowing deliveries, that gauge increase in 2024 will be less than we would have expected. You will see continued pressure from labor of about 3-4 points. That's an industry headwind for CASM-ex, not unique to United. We expect it will lead to higher TRASM to offset, but you should continue to see that. We will lap the majority of that as we enter into the fourth quarter. And then maintenance headwind of about a point, that's gonna be lumpy quarter to quarter. As I sit here today, I think it's about a point in each of the quarters this year. At some point, the supply chain will fix itself in aerospace, but we don't see that today, and I think it probably takes well beyond 2024. So you should think about, to summarize, you should think about the labor and maintenance headwinds as being persistent. Got it. Very clear. And maybe just sticking with you, Mike, you know, the $9 billion CapEx figure that's tied to your contractual commitments, unless I've got that wrong. You know, even as of your last 10-Q before the MAX grounding, you were expecting 17% less aircraft than the contractual amount. Guessing there's probably more downside risk than today given what's going on with the MAX. But, you know, in order of magnitude, does that delta between expected and contractual deliveries largely fit how we should think about downside risk on a dollar basis versus that $9 billion? That delta between contractual and expected is growing, and we don't know exactly where it's settled yet. That's what we're working through now. And we are working, working on an alternate strategy, strategy to mitigate some of the loss in growth. But, but yes, as you're thinking about CapEx coming below $9 billion this year and the trajectory for maybe lower than what you would expect CapEx in 2025 and beyond, that's how you, that's how you should think about it. All right, we'll go to the next caller in queue. Scott Group from Wolfe Research. Scott, your line is unmuted. Hey, thanks. Good morning. So Mike, I totally get your message that the plan is fluid and flexible. But, you know, as it stands today, I'm just wondering, do you think RASM is gonna be positive this year? And then, you know, maybe just, c an you help us just think about shaping the year a little bit? So if I look at last year, right, a pretty massive second quarter and then moderation in the second half of the year, are you thinking a similar shape or maybe more back half weighted? Any color in there would be helpful. Scott, I'll kick it off and say, yes, we think TRASM for the year will be positive, but the details will come from Andrew. Well, we're not giving exact guidance here other than, yeah, we're very bullish on the year. I think I laid out a business case where domestic is starting the year incredibly strong. I think we've laid out a business case for where we're gonna do, you know, with transatlantic capacity. And I do expect Asia capacity to step down materially as we head into Q2 and then Q3, which is obviously gonna bolster those numbers too. So, I remain bullish on the year. Mike, I don't know if you had any thoughts on shaping the year for us, if you have any color. And then maybe just my other follow-up, just for Andrew, just on the point about domestic and international margins converging a little bit this year. Maybe just I just wanna make sure I'm understanding this right. Is this domestic getting better and international a little less good, or is it they're both improving, but domestic's improving more? Just any additional color there would be great. Thank you. Look, I think we're seeing, I hate to say the word exceptional, but we're seeing really good strength in domestic right now, and I expect that's gonna narrow the gap. International margins are well ahead of domestic margins in 2023, and they'll continue to be well ahead of domestic margins in 2024. But I do think that gap will narrow a bit, based on the RASM outlook that I'm looking at, again, which is pretty darn good for domestic. Yeah, and maybe I'll take the seasonal shape in as well. You know, we're working very diligently to make Q1 a more profitable quarter for United. I think we are well on our way prior to the MAX grounding. Obviously, if you take that out, you can use that to update the estimates as to where we would have been in Q1. We made a lot of changes to how we fly in Q1, and we didn't talk about all those details, but when I look at our RASM strengths, particularly in domestic, I am now confident that all those changes had the desired effect. As we continue to build and make sure that in the future Q1 can, well, it won't ever be our best quarter, to be blunt, that it'll be a much better relative quarter. But our global network, you know, I have to say, in Q2 and Q3, really stands out, and we expect it to be stellar again over those six months in 2024. Scott, if you're specifically asking about the shape of our quarterly earnings through the year, it's gonna look like a normal seasonal pattern, albeit with a slightly bigger loss in the first quarter due to the MAX 9 grounding. All right, we'll go to the next caller in queue, Helane Becker of Cowen. Helane, your line is unmuted. Great. Thanks very much. So here's my two questions. The first question is, as you think about 2026 margins, and maybe you'll update us on May 1st, how do we bridge from the roughly 8% at year-end 2023 to, say, 12%-14% in 2026? Helane, thanks for the question, and we will update our longer-term margin targets at Investor Day. But the tailwinds that we expect from the United Next strategy, from the gauge, from the connectivity, from the preference to fly United, we have proven. It used to be, you know, it was a strategy on a piece of paper. We have proven that it's working. And so as we think about 2024 deliveries being a little less, but 2025 and 2026, of reaccelerating into that United Next strategy, we see, we see just continued momentum. And so as for the specific level of 12%-14% in pacing, we're gonna have to update you on May 1st. But the strategy is working, and we're very confident in an upward trajectory to both earnings and margins. Okay. And then just for my follow-up, you know, your, I think, United Next targets, and obviously, you'll update them again, I suppose, $25 billion of adjusted net debt, as of the end of last year, less than $18 billion for 2026. But the other thing is, how should we think about financing? You know, let's just say $9 billion is off the table for this year. Let's bring it down to $6 billion or $7 billion, plus debt pay down. Like, how should we think about you getting to your target leverage over the next 1-3 years, given the CapEx program, which, you know, might be $7 billion this year, but it might be $9 billion, $8 billion, or $10 billion, 2025 or 2026? Yeah, let me try to give you a high-level view, Helane, and we can, we can dig into more details in the near future. But as I sit here today and I think about the changes in CapEx related to the delay in deliveries, I expect free cash to cover our CapEx in most years, if not all years. And as far as additional paydown of the balance sheet, we would expect that as our margins grow into that low double digit, low teen area, that free cash will, uh, will be quite positive, allowing us to pay down that debt. Now, the pacing will be dependent on how much that CapEx profile changes and how quickly we get to what we think is that long run, long-run higher level of margin. All right. We'll go to the next caller in queue, Duane Pfennigwerth from Evercore. Duane, your line is unmuted. Hey, good morning. Just a couple for me. On international inbound, so basically international point of sale to the U.S., as you look across your network, how recovered is international inbound? How do you think about that growth of that demand set in 2024? And are there any markets that stick out, from a, you know, recovery headroom potential? Sure, Duane, it's Andrew. What I would say is, during the entire recovery, U.S. outbound has been a stronger component of the traffic, really across the board, across the entire globe, and that continues today. You know, I think origin Europe, particularly core Europe, Germany, continues to trail, as well as Japan and Australia. So we'll continue to monitor that. But the U.S. consumer has made up the difference in most regions of the world quite effectively and has resulted in very strong, you know, results over the last year. So, you know, I think the outlook is strong, but when the inbound customer profile starts to rebound, I think that's just further upside in the future. It hasn't happened consistently across the globe yet, but we'll see what 2024 brings. Okay. Just following up there, any specific markets, maybe San Francisco, Asia inbound, you know, any more kind of bullish recovery thoughts there? You know, San Francisco is gonna be very unique over the next 6-9 months. There's a significant amount of runway construction going on in San Francisco that has dramatically limited our ability to fly there. It's also consistent with a slower recovery in that city. So I think that is actually probably okay. But you will see us fly a much-reduced domestic schedule in San Francisco. The international flying continues to be very strong, but the smaller domestic schedule, combined with where we are in the recovery, I think is gonna be just fine for San Francisco in terms of a profit contribution. And San Francisco, Asia, continues to perform exceedingly well. All right, we'll go to the next caller in queue. That will be Andrew Didora from Bank of America. Andrew, your line is unmuted. Hey, good morning, everyone. So Andrew, I guess you mentioned this a little bit in your prepared remarks, but, you know, we've been hearing and seeing some data on corporate travel getting a bit better as well. Could you maybe dig in and, you know, speak to maybe any particular markets or verticals where you see some, you know, any sort of outsized corporate growth? And have you seen this corporate growth sort of broadening out to make it, you know, maybe at a more sustainable level today than at other points in the recovery? Sure. You know, we've all sat on calls and predicted the recovery of business traffic more times than I can count over the last few years. And I will say Q4 was okay. It wasn't spectacular in any way. But as we started January in the new budget season for all of our big corporate clients, we did notice a significant step up. So, it's really early. It's only been a few weeks, and I hesitate to say, "Oh, my gosh, it's fixed," 'cause it's still well behind where it should be relative to GDP growth, of course. But look, it's a really nice step up. We're seeing close-in yield gains as well, that result from that, and I think that's one of the reasons our domestic RASM look is as strong as it is. So hopefully, that continues. At the end of the quarter, of course, we'll report on that and let you know how it looks. But at least for the first two weeks of January, we've gotten off to a really strong start, and it gives us increasing signs that this is gonna be, I think, a very good year. Got it. That's helpful. And then, my second question, Mike, you know, obviously a lot of talk on the call just on your, you know, future free cash flow potential. Just when you're, you know, when you're looking at your free cash flow, when do you anticipate you'll become a cash taxpayer? Thank you. Andrew, I think it's a few years off still. Let me get with my treasurer, Pam Hendry, and follow up with you on the precise year. It does depend on how CapEx moderates, and it depends on that profitability, but it's still a few years off. All right, we'll go to the next caller in queue. That would be Brandon Oglenski from Barclays. Please go ahead. Brandon, your line is unmuted. Hey. Hey, Hey, good morning, and thanks for taking my question. I'll just keep it to one here at the end of the call. But maybe Scott or Mike, I mean, you know, coming back to the context that your stock is trading like 3 or 4x PE, probably for the second year here, and also giving you guys credit, because I know a lot of us didn't think you could hit those United Next targets, you know, so many years out. But you are guiding to roughly, you know, flat margins at the midpoint this year. And I think what investors are worried about is, you know, things you can control or at least perceived control, like cost that, you know, are going up for the industry here. Is this just a continued view that United is gonna decouple from industry trends, where you're gonna be able to drive a margin premium? And I guess, what can you give investors confidence that that is the path forward here? Thank you. Thanks, Brandon. Look, I think that it's a structural change in the industry, and we see ton of evidence in this year, and I think eventually, the investment community will see it as well. But there is this is an industry that has operated as a commodity industry, and United and one of our legacy peers have clearly differentiated ourselves from the pack. And that's leading customers to choose to fly our airlines. It's leading to the majority, if not all, of the revenue growth in the industry accruing to those two airlines. And that is happening simultaneous with cost convergence. That cost convergence, the whole reason that the low-cost carriers existed is because they had lower costs. Those lower costs no longer exist. And so that creates, I think, a permanence to the higher margin, a sustainability to that higher margin, and where that settles, you know we still, the jury is still out exactly where that settles. But it is higher and more stable and more resilient, and that is not recognized by the capital markets today. Thank you. ... All right. We're going to go to our next caller in queue, David Bernstein from, sorry, David Vernon from Bernstein. Thank you. Good afternoon, or good morning. Thanks for taking the question. So Andrew, I'd like to get some help from you, if you can, in terms of helping to think through how some of the negative margin capacity that's gonna be forced out of the industry is gonna impact your fare ladder. You know, beyond the upward pressure sort of general vagueness, I'm just trying to, like, understand, you know, if we see a bunch of basic capacity rationalized because some of these negative margin unbundled carriers have to take capacity out, is that how is that gonna impact sort of basic fares versus economy fares? Anything you could give us to help translate that impact of capacity shift into, you know, how, what sort of impact it's gonna have on your fare ladder would be really helpful. I mean, I think that's probably a lot more detail than I can do on a conference call, to be honest. But, you know, just generally, you know, unproductive capacity has been leaving the system. I think that's been good for the system and good for United. And so we'll manage our RM like we normally do to take advantage of all of the opportunities. But I just want to reiterate that, you know, our choice to diversify our revenues at the top with Polaris and at the bottom with Basic Economy is not something we're gonna be giving up on. The Basic Economy is an important part of the airline. It is what our customers want. We will continue to provide choice, and we expect to provide more and more of it as our gauge increases. The competitive dynamics are what they are. I can't predict them. I only really can talk for United, and we'll obviously maximize our returns and do the right thing. But again, the diversified revenue streams that we're putting out there are really working for us across not only the fare ladder, but our geographic dispersion of our flying. And so we couldn't be more pleased with our revenue results, quarter after quarter, by the way, not just in Q4 and not just last year, and the outlook we have. This industry is dynamic. It's always changing. We'll change with it, but it is, I think, a good time to be at United Airlines and be an investor in United Airlines. Are you seeing any sort of benefit yet from some of that capacity rationalization as you look forward into the forward bookings? Or do you think that's something that's gonna develop as we get through the year? Look, I think our outlook for Q1, for domestic PRASM, says it all. We will now switch to the media portion of the call. If you would like to ask a question as a member of the media, you may dial pound two on your telephone keypad. You'll hear a notification when your line is unmuted, at which point, please state your question. Again, dialing pound two on your telephone keypad will indicate that you wish to ask a question. All right, we'll go to the first caller in queue, David Slotnick of The Points Guy. Please go ahead. Hi, good morning. Thanks for the question. I know you talked about London and about slower growth across the Atlantic. I was wondering if you could talk about it more from a consumer perspective. You know, there's been some talk just about all the capacity across the Atlantic next summer. Do you see any impact on ticket prices? Do you see them going down or up, just given all that? Thanks. Hey, David. You know, what I would tell you is that, we're prepared for an incredibly strong summer. As I've said numerous times, we decided to go slow this year. We've tilted more of our capacity, particularly in Q1, to Southern Europe. And that's probably what I would say the biggest change is what we see with the consumer, is that destinations in Spain and Italy have become more year-round destinations than seasonal, and that is new post-pandemic, and we're reacting to it and moving more and more capacity out of Northern Europe, out of London Heathrow, or Germany, and into Southern Europe, and we'll probably do more of that again next year. In terms of the price points, I'm not gonna exactly predict that, at this point. We don't normally talk about pricing, but I, I would just say we expect a really strong summer across the Atlantic. Our capacity is not growing materially, and we think that's gonna really allow us to get all of the capacity we've added over the last few years to be mature and incredibly and solidly profitable in 2024. All right. We'll go to the next caller in queue. That will be, Rajesh Singh from Reuters. Please go ahead, Rajesh. Your line is unmuted. Thanks operator. Good day. Hi, Scott. You made some comments on CNBC this morning that MAX grounding broke the camel's back. Do you have confidence in Boeing's current leadership that it will be able to fix its problems? That some people have called the leadership into question and have faulted it for all the quality problems. So do you have confidence in the current leadership? Boeing has a storied history and thousands of great people. They're one of the best engineering, they're one of the best technology companies in history. They're, you know, they've been a great American company. They're our biggest exporter. I have, you know, they're going through a rough patch right now, but I believe that Boeing is, across the board, from top to bottom, is committed to changing and fixing it. I'm encouraging them to do it even faster. And it is gonna impact United in the near term because of some of the challenges they've had, but there are great people there, and they will get it together. And we are their biggest, we'll be a critic at times, we're also their biggest cheerleader. There's no one that's a bigger supporter that wants Boeing to succeed, outside of Boeing than me, and I'll do everything I can to help. Just one clarification, Scott, about your comments about MAX 10. Some people are misconstruing it, that you are planning to cancel the order. Can you clarify your comments about MAX 10? We are not canceling the order. We are taking it out of our internal plans, and we'll be working on what that means exactly with Boeing. But Boeing's not gonna be able to meet their contractual deliveries on at least many of those airplanes. I'll just leave it at that. That is all the time we have for questions today. I will now turn the call back over to Kristina Edwards for closing remarks. Thanks for joining the call today. Please contact Investor and Media Relations if you have any further questions, and we look forward to talking to you next quarter.
