Flight crews have racked up quite the track record for unleashing hell on passengers by being super mean to them: Whether it’s kicking Alec Baldwin off a flight for playing Words With Friends or kicking a guy off for having baggy jeans, flight crews have been a united front in passenger their intimidation.

But two flight attendants on American Airlines managed to pull off what might have been a first yesterday afternoon, delaying a flight at New York’s JFK four hours by getting into an argument with each other.

It started like most epic arguments do: with some passive-aggressive cattiness. As one flight attendant was getting ready to make the PA announcement about turnring off all cell phones and electronic devices, she saw a co-worker on the flight crew talking on the phone. She went ahead and made the announcement, asking everyone to turn off all phones and electronic devices, “including the other flight attendent.”

The flight attendent on the phone apparently did not appreciate being called out over the intercom in front of hundreds of passengers. An epic argument erupted between the two. Next thing passengers knew, the the plane was headed back to the gate.

NBC reports: “‘We were informed we were going back to the gate because the flight attendants couldn’t work with each other,’ passenger Dan Alexander told NBCNewYork.com.” One of the flight attendants left the plane and passengers waited four hours for American to find a replacement for the flight crew.

The best part? It was a one-hour shuttle flight between New York and Washington, DC.

It’s official: Flight attendants are the new Postal workers.
