A former United Airlines pilot, John Paul Castillo III, has filed a federal lawsuit accusing the carrier of discrimination, retaliation, and defamation following his termination.
Castillo alleges United violated the ADA and Title VII by firing him due to a perceived alcohol-use disorder (despite an independent evaluation finding none) and because he is Hispanic, citing disparate treatment compared to other pilots.
The lawsuit also claims United retaliated against him for hiring a lawyer and defamed him by falsely reporting "pilot-performance issues" to the FAA.

A former United pilot has filed a federal lawsuit accusing the carrier of discrimination, retaliation, and defamation following his termination last year.
