Ryanair said that its crew did not tell the passenger to crawl off the plane.
Gothenburg’s Landvetter airport has since apologised to Keogh. .
In an interview with BBC Nothern Ireland Keogh said he was in pain after the flight and needed to use the toilet, which he could not do on the plane.
“The Landvetter authorities blamed Ryanair and Ryanair blamed Landvetter. They especially didn’t want us taking the picture,” wrote Keogh on his Instagram account.
Keogh said that the service was “unacceptable”, especially having paid an additional fee for wheelchair assistance.
A spokesperson for Ryanair said that wheelchair and accessibility services were operated by the airport.
The airline told Sky News it “regret[s] that Landvetter Airport failed to provide special assistance to this passenger upon arrival at Landvetter on 29 Apr and we are working with Landvetter Airport to ensure this does not recur”.
In its apology to Keogh, the airport said wheelchair assistance was unavailable because of another medical emergency and service delays.
“With several booked assistants requirements, including yours, and a medical emergency simultaneously, caused a [delay]. Your assistance service was not forgotten but delayed,” read the letter.
Keogh, who has been a wheelchair user since 2015, said it was not the first time he had faced unreasonable delays on planes because of his need for assistance.
“I am not looking for anything, only the service I paid for and to be able to travel with dignity.”
