Good morning, everyone. And welcome to the American Airlines Group's first quarter 2019 earnings conference call. With us in the room this morning is Doug Parker, Chairman and CEO; Robert Isom, President; and Derek Kerr, our Chief Finance Officer. Also in the room for our question-and-answer session are several of our senior exes, including Maya Leibman, Chief Information Officer; Steve Johnson, our EVP of Corporate Affairs, Elise Eberwein, our EVP of People and Communications and Don Casey, our Senior Vice President of Revenue Management. Like we normally do, Doug will start the call with an overview of our financial results. Derek will then walk us through the details on the first quarter and provide some additional information on our 2019 guidance for the remainder of the year. Robert will then follow with commentary on the operational performance and revenue environment. And then, after we hear from those comments, we'll open the call for analysts' questions, and then lastly questions from the media. To get in as many questions as possible, please do limit yourself to one question and a follow-up. Before we begin, we must state that today's call does contain forward-looking statements, including statements concerning future revenues and costs, forecast or capacity, traffic, load factor, fleet plans and fuel prices. These statements represent our predictions and expectations as to future events, but numerous risks and uncertainties could cause actual results to differ from those projected. Information about some of these risks and uncertainties can be found in our earnings press release issued this morning in our Form 10-Q for the quarter ended March 31, 2019. In addition, we will be discussing certain non-GAAP financial measures this morning, such as pre-tax profit and CASM, excluding unusual items. A reconciliation of those numbers to the GAAP financial measures is included in the earnings press release and that can also be found on the Investor Relations section of our website. A webcast of this call will also be archived on the website, the information that we're giving you on the call is as of today's date and we undertake no obligation to update the information subsequently. So thanks again for joining us. At this point, I’d like to the turn the call over to our Chairman and CEO, Doug Parker.
