American Airlines Group Inc. is an American publicly traded airline holding company headquartered in Fort Worth, Texas. It was formed on December 9, 2013, by the merger of AMR Corporation, the parent company of American Airlines, and US Airways Group, the parent company of US Airways. Integration was completed when the Federal Aviation Administration granted a single operating certificate for both carriers on April 8, 2015, and all flights now operate under the American Airlines brand. The group operates the largest airline in the world, as measured by number of passengers carried, by fleet size and by scheduled passenger-kilometers flown. The company ranked No. 70 in the Fortune 500 list of the largest United States corporations based on its 2019 revenue, but, impacted by the COVID-19 pandemic, it lost $2.2 billion in the first quarter of 2020 alone and accepted government aid.
