Delta flight attendants threatened to forcibly remove a disabled man from a flight after his wheelchair failed to turn up.
Cory Lee, who suffers from spinal muscular atrophy, was on a flight to Atlanta from Santiago when he was waiting to disembark the plane.
He was told by flight attendants his wheelchair hadn't arrived from the gate but the passenger said he would wait until his chair was ready.
However, according to Cory, the crew members became angry and insisted he left the plane - despite there being no wheelchair for him.
He told the flight attendants he wasn't going anywhere and said the Air Carrier Access Act demands the airline lets him stay on the plane until his chair is ready.
Cory, an accessibility travel blogger from Georgia, US, posted the distressing video of the flight attendants getting angry at him on his Instagram.
He wrote: "I told the airport crew and flight attendants that I would just stay on the plane until my wheelchair was brought to the door of the plane.
"They immediately got livid."
In the shocking video a flight attendant is seen talking to a colleague who says "they're not leaving" in reference to Cory and a woman he was travelling with.
When Cory demanded to speak with a supervisor the flight attendant said she would carry him down the aisle, which he refused - as he waited for his wheelchair to appear.
Cory told Fox News: "They were talking to each other, saying, 'He just doesn't want to get off the plane'.
"Believe me, I definitely wanted to get off the plane."
The supervisor asked the passenger to leave the plane and said she would get the Transportation Security Administration to take him off if he didn't leave.
A crew member can be heard saying in the video: "They're going to come and they're going to make you get off the aircraft.
"They're gonna have their guns and stuff and they are gonna make you get off."
Cory said a ground member quickly intervened after hearing his ordeal and went about securing his wheelchair.
He wrote on Instagram: "'The ground crew guy (Mr Flowers) was very apologetic and found a way to quickly bring my wheelchair to the plane door.
"After being threatened with guns, it was relieving to have his help and kindness."
After the flight attendant's angry outburst he was finally removed eight minutes later as Cory admitted he "did not want to cave to pressure. I know the law."
Delta has since apologised to Mr Lee and said the video does not reflect the high standards they expect.
It said: "The exchange in this video does not reflect the high standard of care Delta people aspire to every day.
"We are reviewing what occurred here and will follow up as appropriate with our people. Delta has reached out to this customer directly to hear more about what they experienced and to offer further apologies."
