Thanks, Andrew. For the first quarter, we delivered earnings per share of $0.91, ahead of expectations and within our guidance. Our pre-tax margin was 3.3%, up 3.6 points year-over-year, and the strongest first quarter we've had in the last five years. We expect these results to lead the industry and further demonstrate the success of our United Next plan. As Andrew just described, at the start of February, we saw a steep drop in US government and government-adjacent travel. We guide, however, with a no excuses philosophy. So seeing the pressure on revenue, we doubled down on managing costs to ensure we would deliver within the first quarter EPS guidance range. Those efforts, along with favorable timing of a few maintenance events, led to a first quarter CASM X result of up only 0.3% year-over-year. These actions, combined with lower fuel costs, enabled us to deliver on our guidance. I'm proud of the team for their hard work in making sure we delivered on our first quarter financial commitments. Looking to the second quarter, we expect earnings per share to be between $3.25 and $4.25. We are acutely focused on booking trends and the potential impact of tariffs. And we are closely monitoring the situation. And it is a risk. But today, our bookings have stabilized. Looking out to the third quarter and beyond, we've already taken action to pull down our less profitable flying, including Redeye flying, capacity in US government traffic-heavy routes, and transborder flying. Aided by accelerating the retirement of 21 aircraft. We were the first airline to recognize slowing demand from US government spending and to take appropriate action. We expect our domestic capacity to come down four points from our original plan starting in the third quarter. There's a tremendous amount of uncertainty in the economy right now, and we've already seen a reduction in demand and correspondingly in revenue. But we've seen stability at that lower demand level in the last six weeks. And the silver lining is we also expect a significant reduction in our fuel cost. If demand remains stable for the balance of the year, that combination of revenue decline and fuel cost reduction, along with the fact that we built a significant contingency into our initial guide, leaves me cautiously optimistic that we can still deliver full-year earnings per share within our guidance range of $11.50 to $13.50. While we've seen stability in demand for the past six weeks, we also recognize that there's a real risk of the US economy going into a recession. If we enter a recession, we are modeling an additional five-point reduction in total revenue for the remainder of the year, on average per quarter. In that scenario, we would make an additional downward adjustment to capacity, and we have not assumed any further relief in fuel price, even though that might happen. Even in that world, we expect a full-year earnings per share to be between $7 and $9. While that is not what our expectations were at the start of the year, that scenario would be the first time United would have remained solidly profitable through a recession. We believe it would justify significant multiple expansion as we will have proven our financial resiliency, our greatly improved competitive position, and the durability of a decommoditized business powered by brand loyal customers. Turning to the balance sheet. We ended the first quarter with $18.3 billion in liquidity, including our undrawn revolver. We generated over $2 billion of free cash flow and paid down $1 billion of debt. In fact, over the last twelve months, we've generated over $5 billion in free cash flow, representing approximately 130% of our net income. At our current equity valuation, that represents an over 20% free cash flow yield. Our net leverage was reduced to 2.0 times from 2.2 times at the end of 2024, marking continued progress as we work towards our long-term net leverage target of less than two times. Recognizing our progress, Fitch upgraded United to BBB with a positive outlook, with a change to a positive outlook from Moody's as well. On the buyback, as of April 10th, we've repurchased approximately 5.6 million shares in 2025 at an average price of $80. History has taught us that even industry leaders are prone to steep market overcorrections in times like this, and we built our buyback strategy around being opportunistic. We believe this is precisely the right time to repurchase our shares at our current depressed valuation, with approximately $1 billion left in authorization. Regardless of the economic path ahead, we expect our financial results to be resilient. We believe that the long-term earnings power of our company hasn't changed, and frankly, it's possible that some of the weaker airlines may be forced to curtail money-losing capacity sooner than they otherwise might have. Therefore, our view of the intrinsic value of our shares also hasn't changed. In fact, as I mentioned earlier, we believe our multiples should expand as we prove that our business is stronger and more resilient even in a time of economic stress. For as long as our share price remains depressed, we plan to continue to utilize a meaningful portion of free cash flow to repurchase shares at what we believe are discounted prices. As I've mentioned the last several quarters, free cash flow generation remains a top priority. While demand has softened, we continue to expect to generate full-year free cash flow approaching $3 billion in a base case and positive free cash flow even in a downside recession scenario. To close, United's competitive position in the industry is only strengthening. We're focused on leaning into our network strengths, continuing to win brand loyal customers, and delivering on our financial commitments. Now back to Kristina to start the Q&A.
