American Airlines' stock fell sharply by 5.09% during intraday trading, indicating a significant negative reaction from investors.

The stock's decline follows public criticism from White House Deputy James Blair, who detailed severe flight delays experienced with the airline. Blair cited an incident where a flight was delayed 2.5 hours due to empty hydraulic fluid and another where his wife's flight was delayed because the airline "apparently forgot to BOOK A PILOT." He stated he would be taking a new interest in the airline industry following these events.

Further adding to the negative sentiment, former Transportation Secretary Pete Buttigieg criticized the prior administration for rescinding passenger protection laws and urged for their restoration and serious enforcement. This spotlight on potential regulatory rollbacks and operational failures at American Airlines likely contributed to the stock's downward movement.
