Flight attendants are posting mile-high selfies in the latest internet craze, tagging the images with hashtags like #cabincrew, #crewlife, and #lifeofahostie.

The attendants take photos of themselves pouting with heavy makeup and dark sunglasses, smiling sweetly with an empty cabin behind them or posing with fellow attendants.

In one photo, a beautiful young flight attendant is smiling as she sits on the headrests of a row of seats, and in another image, even the captains got involved.

While it seems like harmless fun, one expert warns that they could be fired for posting the pictures of themselves in uniform because airlines are strict about protecting their images.
