A spike in Southwest Airlines planes ruled out of service for mechanical issues cost the carrier millions this year because of delayed and canceled flights.

The lawsuit accused the union of encouraging mechanics to write up issues that Southwest said have no effect on the safety of flights in order to gain leverage on in ongoing contract negotiations.
