"There were some frisky crew on this plane," insiders told The Sun.
"There was snogging and stripping and fumbling between the crew, who were all naked."
Ready to party after a 14-hour flight from the UK, the trio and their crewmates had smuggled cabin booze off the airplane so they wouldn’t have to pay sky-high Singapore prices for alcohol, a spy told the paper.
Once at their hotel, "It didn’t take long for ’spin the bottle’ to start," the spy said.
"It’s a drinking game with ludicrous and increasingly daring forfeits designed to get everyone steaming drunk."
The three called-out crewmates, a woman and two men, were suspended and face possible firing after a supervisor reported them for allegedly running through the hotel without their clothing on a dare.
They romped down a corridor, banging on the doors of other guests, The Sun said.
The expose includes a video clip showing a woman in what appears to be a British Airways uniform exposing her cleavage.
