If you think flight attendants are just servings peanuts and pretzels at 35,000 feet, think again. A Travel & Leisure article reveals that 89% of flight attendants have broken some sort of rule while flying, whether it’s having sexual relations with passengers or giving the incorrect change back from duty free sales to a name a few.

Per Travel & Leisure,

A new study by Jetcost.co.uk reveals that 89 percent of airline cabin crewmembers have broken the rules during flight. Most notable: Of the 718 British flight attendants surveyed, 21 percent said they had “indulged in sexual relations with a colleague during a flight” and 14 percent said they’ve engaged in sexual relations with passengers

Still, the most common act of rule breaking, according to the study recently reported by The Telegraph, is lying about the availability of things like duty free products. What’s more, 20 percent revealed they’ve short-changed passengers by giving change in a different currency and relying on the fact that most passengers don’t count their change.
