A boy band singer collapsed during a flight after layering up his clothing to avoid paying an extra baggage fee.

James McElvar, 19, passed out while travelling back from London to Glasgow after performing with Rewind.

EasyJet staff told him was allowed to carry only one bag on board, so instead of paying the £45 (A$92) excess charge, he quickly donned all the clothes he had packed.

The singer got on the plane wearing multiple T-shirts, jumpers, jeans, jackets and hats, but the heat caused him to vomit and pass out.

He was taken off the plane at Glasgow Airport on Wednesday to a waiting ambulance.

The band reassured fans on Twitter: "For everyone asking James is OK. He is being looked after in hospital now back home safe in Glasgow. He sends you all his love."

They later added: "James is much better now. Still in a bit of shock but he's recovered. And the other boys are fine and home safe."

McElvar told The Sun newspaper: "It felt just like I was having a heart attack. I was so hot I felt I would pass out as soon as I boarded.

"I was soaked with sweat and within minutes I was sick. I got moved to another seat but I collapsed moments later. It was a nightmare."
