The wild video picks up with a passenger arguing with a flight attendant, and our sources say the man was losing his cool over being told to keep his face covering on despite claims he was having trouble breathing.

The dispute gets tense and the vulgarities start flying back and forth ... and at one point, the flight attendant threatens to call the cops and tells the passenger, "I'm gonna have your ass arrested!!!"

The incident came to a head when the LAX-JFK flight landed in New York and was met by Port Authority cops who tried to interview the man, but he was uncooperative. We're told he was not arrested on the spot, but police will continue to investigate the incident and charges could be filed at a later date.

We're told the passenger claimed he had a medical issue and needed air ... but as you can see, he had no problem yelling and screaming about his flight experience with a buddy on the phone.
