The plaintiffs, who according to TMZ, have worked with the airline for periods ranging from 10 to 40 years, say that the airline "intentionally discriminates against ethnically Jewish and Israeli employees and passengers," specifically on flights between NYC and Tel Aviv."
Delta allegedly fired a flight attendant in 2017 because of her Jewishness, though the airline claims it was because she missed her flight. The woman says she was on pregnancy leave at the time.
Another non-Jewish flight attendant claims that she was suspended without pay and demoted when she shared her Delta travelers companion pass with a friend who happened to be Jewish.
Delta accused her of violating company policy because she did not actually know the beneficiary of the pass; she claims that the two have been friends for 40 years.
Other suit also alleges that Delta creates a hostile work environment for Jews and Israelis and denies them of promotions.
The four plaintiffs are suing for damages and asking for the fired flight attendant to be reinstated and for the promotion of their demoted colleague.
"Delta strongly condemns the allegations of discrimination described in this suit and will defend itself vigorously against them," Delta spokesman Morgan Durrant said in response to the lawsuit.
"As a global airline that brings people across the world together every day, Delta values diversity in all aspects of its business and has zero tolerance for discrimination."
