An American Eagle flight from JFK to National Airport was delayed about four and a half hours Wednesday after two flight attendants apparently had an argument.
One of the flight attendants on American Eagle Flight 3823 said the other refused to work with her, according to one passenger.
The cockpit crew was alerted and decided to kick the flight attendants off the plane. The pilot turned the plane around and went back to the gate.
"We were informed we were going back to the gate because the flight attendants couldn't work with each other," Dan Alexander said.
"I find it hard to believe the flight attendants couldn't work with each other for an hour," he added, noting the approximate flight time from New York to Washington.
The flight, which had been scheduled to leave New York at 3:10 p.m., was delayed as the airline searched for a replacement flight attendant crew.
"It was incredible, totally unbelievable that there was such little professionalism between these women," Marge Lopez said.
Karen Grantham said it was "ridiculous" that the flight attendants became upset.
"Doesn't anyone teach good customer service anymore?" she asked. "You have to be thick-skinned to be in customer service. It just happens, you can't let this get the best of you."
Both flight attendants will meet with their supervisors to determine if whether they should face any disciplinary action.
American Airlines did not immediately respond to a request for comment.
The airline has already been dealing with scheduling problems and delays. It said it was forced to cancel 300 flights this week because a high number of pilots were calling out sick and crews were filing more maintenance reports.
AMR Corp., which owns American Airlines and American Eagle, said Wednesday that it canceled the flights in advance to avoid inconveniencing passengers.
Earlier this week, American said it would cut its schedule through the end of October by up to 2 percent.
The Wall Street Journal's veteran travel reporter, Scott McCartney, on Tuesday told travelers to avoid the carrier because "American's operation is in shambles."
McCartney said American Airlines is too unreliable because of trouble with the pilots union.
Denny Kelly, an aviation expert and former pilot, told NBC DFW he agreed that travelers should avoid the Fort Worth-based airline.
"If you're going to fly a trip from Dallas to someplace and you have a choice, and you have to be there on time or within a reasonable amount of time ... why take a chance on American?" he said. "Why take a chance on [if] a flight's going to be delayed or canceled? Go on somebody else that doesn't have that problem."
