AAL Stock: What to Know About the American Airlines Flights Cancelled American Airlines (NASDAQ: AAL ) stock is down today after cancelling at least 66 flights in the U.S. on Sunday night. AAL is in the red about 1.5% this morning as the high-flyer attempts some damage control for its recent flight cuts. The news comes following American’s brutal schedule reduction last week, in which the airline announced it’s ending service in a number of small cities. American joined fellow domestic airlines in Sunday’s catastrophic string of flight cancellations. At least 730 domestic flights were cancelled that day, with Delta Air Lines (NYSE: DAL ) and United Airlines (NASDAQ: UAL ) posting 224 and 71 cuts, respectively. It’s not the first time American has been in the doghouse over cancelled flights, however. On its schedule reductions, the company recently told CBS: “In response to the regional pilot shortage affecting the airline industry, American Airlines has made the difficult decision to end service in Dubuque, Iowa, Islip and Ithaca, New York, and Toledo, Ohio.” It seems staffing shortages, increased fuel costs and surging summer travel demand continue to weigh heavily on airlines.
