Southwest Airlines has been under public scrutiny recently for its employees' conduct.
United Airlines CEO Scott Kirby said the company's mask-related incidents have decreased 50 percent this year.
"Honestly, she most likely has tried being nice about it in the past and it didn't work," said one commenter who praised the flight attendant.
Flight 175 was a route I worked on all the time. Of course, I knew the crew who were on that flight on 9/11. It might sound crazy but I almost wanted to have been on that flight. I would have rather been up there battling with those terrorists. I just couldn't comprehend those crew members being hurt.
"They all deserved to be able to fly home and hug their loved ones again," the flight attendant said. "We were proud to honor and fly with them today."
"Frontier Airlines maintains the utmost value, respect, concern and support for all of our flight attendants," a spokeswoman from the airline said.
"Keep him down, keep him down," one person can be heard saying in a video of the incident.
Spirit Airlines said videos and photos shared online do not accurately represent what happened on the flight. A spokesperson told Newsweek that the family was asked to leave the aircraft because of the parent's non-compliance and added that no flight attendants were removed by the police.
The video begins during the conversation with the passenger—who is unnamed—telling the Spirit Airlines employee that he is wearing a mask.
On Sunday, the president of the Association of Flight Attendants–CWA (AFA-CWA), Sara Nelson, expressed her anger for the lack of protective masks on a packed passenger plane.
The woman was tested after fellow crew members became suspicious.
The man admitted that he took the videos, but denies distributing any of them.
"I thought to myself, there's only one thing I could offer and that's my own milk. And so I offered," Organo wrote on Facebook.
The flight attendant was off-duty at the time of the alleged incident.
The woman was was met by local police upon her exit from the plane.
A United Airlines pilot allegedly posted explicit photos of a flight attendant online, some featuring the tagline "Fly the Friendly Skies."
"She became agitated and said, 'If you're gonna act like that we can go back to the gate and you can get off.' I held up my phone to show her that airplane mode was on."
Researchers think the U.S. needs to update its safety practices.
Kaliningrad received its current name by the Soviet Union, after serving as a German bastion in Eastern Europe for centuries.
Patricia Casey was going through a "messy divorce" and "self-medicating" with alcohol.
Passengers and social media users alike are outraged after video surfaced showing Southwest Airlines bringing a taxiing plane back to the gate to kick off a previously unruly young girl and the toddler's parents.
The woman was also accused of kicking a flight attendant and breaking free of her flex cuffs.
The charges were filed one year after Frontier pilots claimed similar discrimination.
