An air hostess reportedly earned around £650,000 over a two year period by having sex with plane passengers in the toilet.
The scale of the woman's 'business' only came to light when she was caught in the lavatory recently, and she was subsequently sacked.
It is reported that she was working for an airline in the Middle East.
A source speaking to the Saudi Arabic language dail Sada said: 'She admitted that she had sex with many other passengers during flight and that she preferred long distance flights between the Gulf and the United States.'
Airline sources believe the woman charged £1,500 (Dh7,400) for the mile high liaison, an amount she earned on every flight.
The airline has not been named specifically, but Sada has reported that the flight attendant was immediately sacked and then deported.
Speaking to MailOnline Travel, Antoine Michelat, co-founder of flight comparison website Jetcost.co.uk, said: 'Flight attendants have always had a special charm with their passengers; while some attendants choose not to cross a line and take advantage of this, there are always going to be those who do.
'The amount of £650,000 seems like an awfully high number and we're not sure how believable this is although I suppose that all depends on if the person in question had illicit liaisons with business passengers and just how wealthy they were.'
Earlier this year, MailOnline reported that some cash-strapped air stewardesses in Japan are turning to prostitution in order to supplement decreasing wages.
Several unnamed flight attendants have been quoted in the Shukan Post claiming that female cabin crew are regularly paid to sleep with the pilots.
According to the women, staff can charge between £300 and £450 for 90 minutes with a client.
