A few customers decided to air out their wet bikinis on a recent journey by hanging them over the headrests of seats on their flight.

A passenger shared the photo on Instagram which was like by more than 3,000 people and many slammed the people who took the liberty - and complained they would have made the plane smell of chlorine.

However, some people defended the passengers.

One person wrote: ''It's a pretty empty flight. Looks like no one sitting in the row being used for laundry.''

A second person joked that at least it was better than them hanging a ''dirty diaper'' over the top of the seat.
