Thanks, Crystal. And good morning, everyone, and welcome to the American Airlines Group First Quarter 2021 Earnings Conference Call. Joining us on the call this morning, we have Doug Parker, Chairman and CEO; Robert Isom, President; and Derek Kerr, Chief Financial Officer. Also on the call for our question-and-answer session are several of our senior executives including Maya Leibman, Steve Johnson, Vasu Raja, Alison Taylor and Devon May. Like we normally do, Doug will start the call with an overview of our quarter and the actions we've taken during this pandemic. Robert will then follow with some remarks about our commercial and other strategic initiatives. After Robert's remarks, Derek will follow with the details on the quarter and our operating plans going forward. After Derek's comments, we'll open the call for analyst questions, and lastly, questions from the media. [Operator Instructions]. Before we begin, we must state that today's call does contain forward-looking statements, including statements concerning future revenues, costs, forecast, capacity, fleet plans and liquidity. 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 and our Form 10-Q for the quarter ended March 31, 2021. In addition, we will be discussing certain non-GAAP financial measures this morning, which exclude the impact of unusual items. A reconciliation to those numbers to the GAAP financials is included in the earnings release, and that can be found on the Investor Relations section of our website. A webcast of this call will also be archived on our website, and 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 turn the call over to our Chairman and CEO, Doug Parker.
