American Airlines Group Inc. asked a federal court to halt an "illegal slowdown campaign" by unionized employees, saying the action had disrupted the travel plans of 125,000 passengers in the last three months.
Mechanics are taking too long to repair jetliners and refusing to work overtime in an effort to gain leverage in contract talks, American said in a lawsuit filed Monday in federal court in Fort Worth, Texas.
The alleged slowdown will crimp travel for 3,400 passengers a day if it continues into the summer, the airline said.
