"Tracey is mortified that the video is doing the rounds on the internet," one pal told The Sun.
"She has gone into hiding as she is getting all sorts of accusations thrown at her. She insists she wasn't having sex with the guy, but admits it looks bad."
Bolton has told her supporters that she was simply giving Edmondson, a sous chef she met before boarding, a lap dance.
He was on a buck's party trip with friends to Ibiza when he and Ms Bolton - who was also travelling with girlfriends for a hen's do - decided to get intimate at 32,000 feet.
In the video, he can be heard yelling: "Anyone got any jelly?" A jelly is a colloquialism for condom.
Kieran Williams was a passenger on the flight and witnessed the shocking scene, and said he initially thought they were joking.
"We all laughed but then 10 minutes later they actually did it. They seemed so drunk, they brought a lot of attention to themselves.
"You could see the girl taking off her pants and he pulled his trousers off. She started riding him. I had to get my phone out. I have never seen anything like that."
Pals say his fiancee Jenna, who was born in Canada and has been with Edmondson for six years, is now well aware of the footage and is fuming at his behaviour.
Despite appearances, her father Stephen told The Sun that people had the story "mixed up".
"They have got the wrong side of the story," he said.
Another of Bolton's friends, Kirsty Lawton, also insisted there was "no sexy time" between the pair and it was just a lap dance "for a laugh".
"The pair of them were being daft and it was all for a laugh. They didn't know one another. As if you would do that with anyone let alone a stranger."
A spokesman for Ryanair said the company was investigating the incident.
"We will not tolerate unruly, disruptive or inappropriate behaviour at any time and any passengers who appear to behave in an unacceptable manner may be liable for further sanctions."
