Andy Eisenmann, an arts educator, was flying from Dallas Fort Worth to Palm Springs on 22 November when he spotted what he alleged were maskless American Airlines employees at the airport before the flight.
He took a picture of the two men, who do not appear to be eating or drinking – the only times masks are not required – and shared it on social media.
“AA no masker [flight attendants] at DFW. 30+ minutes at gate,” tweeted Mr Eisenmann.
He claims that, 30 minutes before the plane landed, he “quietly” complained to a flight attendant that he had been “offended” by the crew’s decision not to wear masks at the airport.
When the aircraft touched down, Mr Eisenmann alleges he was met by police for being “unruly” and taken to a small hold room with no vents for questioning.
“Their PSP ops person questioned me in close quarters for doing nothing at all wrong,” he said.
“AA won’t tell me HOW I was ‘unruly’. Empowered horrid employee had me BASELESSLY LOCKED UP W POLICE!”
He claimed that the flight attendants “lied to police saying I was unruly” and said he was “humiliated” by the experience.
An AA spokesperson told The Independent that Mr Eisenmann was not detained and that law enforcement had been called as a precaution after a disturbance was reported onboard the flight.
