Thanks Kate. In the second quarter, PRASM growth accelerated to up 2.5%, which was at the high end of our unit revenue expectations at the start of the quarter. Passenger revenue growth was up 6.1%. Overall, we are pleased with our revenue performance and our ability to successfully work through the headwinds we encountered during the quarter. The growing success of our commercial initiatives helped us navigate a challenging environment and produce strong revenue result regardless. Our best-performing region in the second quarter was Latin America. On our last call, I described the outlook for Latin America as stellar and in fact it was even better than that. Second quarter PRASM increased 9.1%, which is above our early expectations and represents the highest growth for any entity and quarter over the last few years. Demand for our flights is strong across most of the region and we expect continued strong performance in the third quarter, albeit at a more moderate level. Performance across the Pacific also had strong showing in the quarter with a 2.8% increase in PRASM. I have to say the Pacific was maybe our biggest surprise given all the negative trade headlines we saw earlier this year. While China -- the China portion of our Pacific entity did have some volatility in the quarter, we're able to manage other parts of the region to more than offset. Increased collaboration between United and ANA our joint venture partner in the Pacific was a clear driver of this performance. We expect -- expected a negative impact to the Atlantic in the quarter due to a later Easter holiday, where PRASM did inflect versus the first quarter and increased by 0.6%. While the domestic PRASM in the quarter increased 1.9% on a 4.0% increase in capacity, close-in business demand was strong. And it's interesting to note that excluding Hawaii, our domestic PRASM would have been up by 2.5 points in the quarter. This is further evidence that our growth at our Mid-Continent hubs is working. Looking ahead to the third quarter, we expect our consolidated passenger unit revenue to be up 0.5% to 2.5%. The domestic and Latin environments look positive with strong demand and yield growth. Hawaii which represents 10% of our domestic capacity had a challenging Q2, but the outlook looks better going forward. For the full year of 2019, we expect that overall capacity growth will result in approximately two points less growth than our original plan due to the grounding of the 737 MAX jets and suspension of India flights. By the end of the second quarter, we were short 19 MAX aircraft and the closure of our two India routes represents the equivalent of another 11 737 aircraft, a significant portion of our capacity. We expect the MAX jets to return to flight no earlier than November 3rd. As you're aware, we suspended service to Delhi on April 4th and Mumbai on June 22nd. However, on Monday night this week, we received great news that Pakistan has reopened their airspace. That news came just hours after we decided to push resumption of our India flights to late October. We're excited to relaunch service back to India as soon as possible. Our team has started our resumption of flight procedures and we can now confirm service will resume to both Delhi and Mumbai on September 6 from New York. For 2019, we now expect full year capacity to be up 3% to 4%. We anticipate we'll be able to make some of these lost capacity up next year, but not all of it. Turning to slide 12, we'll continue to focus on our commercial initiatives. Premium Plus currently represents about 2% of our wide-body ASMs, and we expect that to increase to 8% when fully rolled out. RASM gains for flights with Premium Plus range between 4% and 6% after accounting for all buy-ups and buy-downs. Our first set of CRJ-550s are being prepared to enter service later this year with client focus on Chicago and New York. We expect the 550 will begin to close the structural gap with Premium customers that we have in smaller communities across the United States. In 2020, we expect to begin service from New York, Los Angeles, Chicago and Washington to Tokyo's downtown, Haneda Airport complemented and extended upon our existing flight from San Francisco and building on our industry-leading service to Japan. We rolled out our first of our specialized 767-300 with high premium seat counts for service fares in cities -- to fares with unmet business class demand on United. All flights from Newark and Chicago to London Heathrow are scheduled to be operated by this new fleet type later this year followed by Switzerland in 2020. I'd like to give a shout-out to the operations team who worked with the commercial team to develop this unique product, while also permitting approximately half of our remaining 767s to operate in a typical configuration to destinations not needing as many Polaris seats. These aircraft along with the CRJ-550 are two initiatives focused on capitalizing on the high volume of premium demand in our markets. In the second quarter, corporate revenues which was much closer to departure increased 6% consistent with our top line revenue growth. Over the last eight quarters, we've talked about our pipeline of ideas and innovations that drive improved financial results and customer engagement. One of the many ways we measure the success of our initiatives at United is engagement characteristics of new flyers who take three or more trips per year with us. We are pleased to share that new flyers in early 2019 were up 11%, a noticeable increase year-over-year. What's more we see a strong engagement of these new flyers with United across multiple areas including overall travel spend, being a co-brand cardholder and achieving premier status with MileagePlus. Growth among millennial travelers has also been especially strong, which is critical to securing our next-generation of loyal repeat customers. As we put the customers in the center of everything we do, we're encouraged by these results as much as by our financial results and believe this is yet another validation that our strategy is working even when faced with significant headwinds. Thanks to the entire United team for a great second quarter. And with that, I'll turn it over to Gerry to discuss our financial results.
