Thanks, Ben, and good morning, everyone. Today, my comments will speak to our first quarter results with a focus on unpacking our core performance and addressing second quarter trends and guidance. We achieved record first quarter revenues totaling $2.2 billion, up 1.6% year-over-year. This is an incredible result, especially when you consider the $150 million in revenue that we lost due to the grounding. Our team did a masterful job rethinking the deployment of our Q1 network in order to combat the seasonal challenges we face and to best serve the demand in our geographies. Capacity ended the quarter down 2.1% year-over-year, inclusive of an approximate 5.5 point impact from the grounding. This result was better than our initial expectation immediately following the accident due to high utilization, a better-than-expected completion rate and no significant winter weather. Absent the grounding, capacity would have been up approximately 3.5%, a level we feel was appropriate for the Q1 environment and our network reconfiguration. In addition to our focused network efforts, we were positively impacted by the rapid return of corporate travel revenues and general close-in strength, which drove a strong unit revenue result. For the quarter, unit revenue was up 3.8% year-over-year. Excluding the impact of the grounding, unit revenue would have been up 5%, which is markedly higher than our original guidance of up 1% to 2%. This outperformance was driven by three factors: First, 1.5 points of RASM outperformance came from better-than-expected results related to the reallocation of flying. These changes more successfully met the demand across our markets, as we capitalized on more leisure flying. Second, 1.5 points of RASM improvement came from a material step up in business travel beginning in January, especially from large technology companies. In Q1, managed business revenue grew 22%, approximately 50% driven from yield and 50% from volume. Tech companies saw the biggest improvement with revenues up over 50% year-over-year and professional services revenue an impressive 20%. To put the speed of recovery into perspective, managed business revenues increased 10% in January, a stunning 30% in February and 24% in March. These results were achieved despite the grounding and book away we experienced. Today, managed corporate revenue has fully recovered the 2019 levels, while tech is approximately 85% recovered. As we've said for some time, we expected business travel to come back which we are clearly seeing today. While we did not bake this into our Q1 forecast, we do not anticipate any step back in corporate travel in Q2. And third, half point of RASM improvement came once we restored our schedule reliability, and we saw strength in close-in leisure demand return. This strength is especially evident in February, where revenue beat our original pre-grounding expectations, despite loss flying and book away at the beginning of the month. Similarly, our total March revenue surpassed our record breaking result last year on just over 1 point lower load factor, bolstered by yields that improved 2 points in month driven by strong close-in performance. Taken altogether, these impacts drove a 3.5 point improvement above the midpoint of our original guide for the quarter. Lastly, our Premium Cabin performance continues to support what we believe to be a structural shift in higher demand for premium products. First and premium class revenues finished up 4% and 11%, respectively, during the quarter, with our first class paid load factor hitting monthly records at 68% during February and 69% in March. What makes these premium revenue results even more significant is that they would have been higher had we not experienced the grounding. Our paid premium capacity has come a long way from the days of paid load factors in the 40% range for mainline and an all coach regional fleet. As we continue to refine our premium strategy across our products and markets, we have further upside to come and remain committed to building on our premium guest experience, offering the products our guests and loyalty members want. Our loyalty program, which we hope to share more on later this year, also continues to post strong results. With co-brand cash remuneration of approximately $430 million in Q1, up 4.2% year-over-year, notwithstanding the grounding and a major contributor to the 48% of revenues we generate outside the main cabin. Now turning to our outlook and guidance. We expect capacity to step up 5% to 7% year-over-year in the second quarter, with the low end of this range, assuming no aircraft are delivered this quarter. Given the uncertainty around delivery timing, following the grounding, we have extended the retirements of several of our older aircraft over the next few months and pushed utilization slightly higher across the Mainline Fleet, where we had opportunity. We also added back more capacity on the regional side through Horizon and SkyWest, given higher utilization from improved pilot staffing. Through the combination of these changes, we are confident in flying a reliable schedule for our guests. While the second quarter will be our highest growth this year, it is also our most profitable growth, with June, a clear peak month for us. While we've added a handful of new routes across our network, the majority of our added flying is focused on additional frequencies in high demand markets, where we've conviction in their profitability. Second quarter bookings so far are encouraging, with yields continuing at healthy levels in April and beyond albeit slightly moderating through the quarter on growing industry capacity. This year, we have seen a more normalized yield and booking curve, building in strength as we get closer in, a trend we expect should persist. Looking beyond Q2, the back half of the year looks to be shaping up well as industry capacity constraints remain in place and competitive intensity dynamics across our West Coast markets stabilize. In closing, the team has done a tremendous job in reshaping our network to produce a strong result for our most seasonally challenged period, with the full value of our differentiated product offering from premium seating to lounges to global partnerships, I believe we are well-positioned to drive another solid quarter of performance, as we move into our peak periods this summer. And with that, I'll pass it over to Shane.
