United isn't the only airline that's under fire these days...

A video has emerged of a Delta Air Lines pilot smacking a passenger who was fighting with another passenger at the Atlanta airport.

TMZ reported that the incident occurred on April 21 after the plane landed at the airport and passengers were deplaning Flight 1827, which flies between Atlanta and Fort Lauderdale, Fla.

Two women started fighting and the Delta pilot, apparently trying to break up the brawl, grabbed one of the women by the arm and struck her with his hand.

The women apparently knew each other and had gotten into an earlier altercation on the plane. Neither of the women wanted to press charges against anyone.

A Delta employee gave a supervisor the video almost immediately after the incident, TMZ reported.

According to Delta, the pilot was removed from duty, but has since returned.

A Delta spokesperson gave a statement to TMZ:

We became aware of this incident and a video last week and immediately removed the pilot from duty while we completed a thorough investigation. Local law enforcement was called to respond at the time of the incident. The pilot has since been returned to work as our investigation found that his actions deescalated an altercation between passengers on the jetway floor during deplaning.

This comes on the heels of the ongoing criticism facing United Airlines after a passenger was violently dragged off a flight.

Watch the video above. (Warning: the clip contains profanity.)
