British Airways said it is investigating claims that one of its flight attendants is working as a prostitute who offers “adult entertainment” and selling her underwear to passengers in between flights.

The unidentified flight attendant reportedly advertises her services through social media snaps and teases that she often wears no underwear during flights.

“If you ever want adult entertainment on-board, all you have to do is give me a sum of money and you’ll be treated to a whole different experience of your choice,” she allegedly wrote on a blog.

According to the Daily Mail AirHostess71’s blog indicates she requires a $66 “securing fee” to meet up in person and the prices for services vary from there.

British Airways told The Sun it had launched an investigation to identify the mystery stewardess based at London-Heathrow airport.

“We expect the highest standard of behavior from all of our colleagues at all times, and we are investigating the claims,” a spokesperson for the airline said.
