If you're a member of the mile-high club, you are among very few Americans who say they have been intimate with a partner on an airborne plane.
If you haven't, it is most likely because you think airplane bathrooms are too small or too disgusting.
Those are among the findings of an online survey of more than 2,000 adults in the U.S.
The survey conducted by Switchfly, a technology company that powers travel booking and loyalty redemption systems, found that 4% of Americans said they have had sex on a plane. An additional 25% said they are willing but haven't had the opportunity.
Among other findings:
--56% say they don't want to join the mile-high club
--Of those who don't want to join, 25% say it's because airplane bathrooms are too small; 25% say the bathrooms are too gross
--Men are three times more likely than women to be members
--Women ages 45 to 54 are more likely than any other female age bracket to be members
--Men ages 35 to 44 are more likely than any other male age bracket to be members
--15% say they don't know what the mile-high club is.
