Flight attendants have admitted to stealing from passengers and having in-flight sexual relations, a survey has revealed.

The survey, carried out by price comparison site Jetcost.co.uk, quizzed 718 former and current British flight attendants about which rules they had broken at work.

The results revealed that 89 per cent of cabin crew had broken rules while at work, with a fifth of those surveyed admitting they had stolen from passengers, the Daily Mail reported.

The most common offence was lying to passengers about product availability during a flight, with 28 per cent of crew admitting to it.

When it came to joining the mile high club, 21 per cent of staff admitted to indulging in sexual relations during a flight, with a further 14 per cent revealing they'd gone there with a passenger.

Seven per cent had accepted tips and gifts from passengers, while 20 per cent admitted to deliberately short-changing passengers.

Respondents who had short-changed passengers were asked to provide details of how they did it, with 54 per cent revealing they had given change in a different currency.

And 40 per cent admitted that most passengers just didn't check their change.

The results showed that the average cabin crew member made £27.60 (NZ$58.14) per month, or £331.20 (NZ$697.70) per year through short-changing passengers.

Jetcost.co.uk founder Antoine Michelat told the Telegraph that it was "completely unacceptable for cabin crew to be short-changing passengers".

"They may think it's OK by passing it off as the odd 20p here and 50p there, but that's still money that's not rightfully yours and belongs to someone else."
