Thanks, Brett. The fourth quarter revenue environment materially improved as the capacity backdrop for the industry became more constructive. United's Q4 TRASM increased 1.6% year-over-year, on a 6.2% increase in capacity. The Sunday after Thanksgiving was our best revenue day in history, shattering the former record by 25%. United's domestic capacity increased 7.8% in Q4, with RASM down 1.9%. We project domestic RASM will turn solidly positive in Q1. The domestic pricing environment is improving as underperforming airlines remove unprofitable capacity at an increase in rate and business traffic growth accelerates. Industry fair sales are less prevalent with lower discount rates, as airlines are prioritizing profitability. All United's hubs were profitable in Q4 and for the last 12 months with only a 7 point pre-tax margin difference between the best and the worst performance hub, the narrowest spread we've recorded in a quarter since 2016. Our network health is very strong with room for margin expansion as we continue our United Next Plan. After years of waiting, we're also finally starting to gain a critical mass of larger narrow-body aircraft, which allows us to execute on our plans to increase gauge. United's international capacity was clearly the star of the quarter in terms of RASM growth relative to Q3. As a result, international margins continue to outpace domestic margins in 2024. United's plan during the pandemic was to double down on international flying and it's proven to be the right move. Q4 Pacific capacity moderated and China headwinds slowed versus Q3 resulting in PRASM flipping from down 15.7% to up 4.1%. Pacific PRASM was up high single digits for the last two-thirds of the quarter versus last year. United has profitably digested a 31% increase in Pacific capacity in 2024, and we have now fully reinstated our pre-pandemic capacity levels across the region with margins that are now above system averages. In the past, the Pacific margins routinely lagged. We plan to moderate our Pacific growth as we head into the first half of 2025 [indiscernible] capacity added in 2024 mature. During 2025, we are excited to launch a new initiative to operate 737s, on a small number of Narita [feed] (ph) flights to destinations in Asia that do not support nonstop service to the U.S. We anticipate this unique initiative made possible by our Guam base will extend our lead, as the largest trans-Pac carrier to build an unmatchable network scope. We're going to redeploy underperforming assets and efficiently grow load factors from Japan to the U.S. where local origin demand still is not fully recovered from the pandemic. 2024 was also a great year for the United Atlantic network, and Q4 was no exception with PRASM up 7.1% on flat capacity. We entered 2024 PRASM capacity growth for the year in the Atlantic after a rapid growth in the region post-pandemic. Our plan for 2024 worked extremely well. All months in Q4 are PRASM positive year-over-year with December RASM up double digit. United is the largest U.S. carrier flying over the Atlantic by ASMs. And in 2025, we plan to have low to minimal capacity growth in Q1 to support continued RASM strength. From what we see today, we expect the first quarter to be our best Atlantic financial result in the company's first quarter history. Latin America trailed the other regions throughout 2024. However, it is important to note that United continued to operate profitably in the region despite these challenges. PRASM was up slightly in Q4, and the outlook for early 2025 is positive. Overall, the momentum for international flying in the fourth quarter was exceptionally strong. We believe the [pandemic] (ph) era global long-haul reset along with a sluggish delivery rate of new wide-body jets sets up the industry really well for years to come in international flying. Cargo also had a very strong showing in 2024. Cargo revenues for the year were up nearly 17% and up almost 30% in Q4 versus last year. It was a very good quarter and year for cargo. The business traffic recovery was a nice tailwind in Q4. Results in Q4 and our outlook for Q1 clearly shows this strength in higher yield corporate traffic volumes. Flown business revenue grew 16% in Q4 year-over-year. We expect that trend to continue in Q1, which is a tailwind for our business-focused network. Contracted business sales in the quarter for all future travel were up 14% year-over-year. Premium passenger revenues increased 10% year-over-year, and premium cabin unit revenues were positive. Both trends have persisted throughout the year. We see no change in consumer behavior seeking out increased premium experiences, but we also remain committed to our most basic product. In Q4, Basic Economy passengers increased 21% year-over-year and now represents 15% of domestic passengers, up 2 points versus 2023. Loyalty revenues grew at a healthy pace at 12% in 2024. Co-brand spend was up 9% with 1 million new card acquisitions. Turning to the product. We reached a milestone of deployment of our signature interior with nearly 50% of the fleet were complete as of year-end 2024. With installation work moving quickly now, we expect to be at 70% by the end of 2025. Across the entire United network, we expect to have 150,000 seatback [indiscernible], full of rich content available to all of our passengers with a better ability to personalize everyone's experience by the end of 2025. As you can see from our first quarter outlook, we continue to make progress on improving the financial performance of that quarter. Changes to our capacity deployment across hubs, days of week and time of day have been very effective. Return to more corporate traffic and the desirability of the Southern European vacation in the winter is also a tailwind. As we announced a few weeks ago, we are tracking ahead of our schedule on Starlink installation, which we think will be a material advantage versus slower [for-pay] (ph) Wi-Fi services offered by other U.S. carriers. United's Starlink plan is yet one more action to elevate our product, creating a brand customers choose more and more often. We will share more on product innovation, merchandising and capacity optimization in the coming year, furthering our lead. We will also talk about how we believe Starlink will unlock a host of new digital benefits for our customers and shareholders. We believe that creating more choice, more segmentation and enhancing our products is the winning formula. Merchandising, sell-in and managing the complexity of these multiple experiences is our proven expertise. With that, I want to say thanks to the entire United team for an amazing 2024, and I'll hand it off to Mike to talk about our financial results. Mike?
