Pilots at American, Southwest, ratchet up strike threats

FILE - The American Airlines logo on top of the American Airlines Center in Dallas, Texas, is pictured on Dec. 19, 2017. Pilots at American Airlines are voting to authorize a strike. That doesn't mean they're going to walk off the job anytime soon, but it does aim to put more pressure on the airline to reach a new contract with the pilots' union. The union said Monday, May 1, 2023 that almost all its members took part in the voting, and that 99% of those who voted authorized the union to call for a strike. (AP Photo/Michael Ainsworth, File)
