Website showcases airline passengers behaving badly

A former flight attendant is on a bit of a mission.

She calls it "passenger shaming", and it's just 'plane' great.

Shawn Kathleen has launched a website where she posts pictures of passengers behaving badly.

Some of the gems include:

A dirty diaper left in the seatback pocket.

A man who fell asleep shirtless.

A woman whose shorts are at a higher altitude than the plane itself.

Oh, and then there's the passenger who got a little TOO comfortable - putting his feet on top of the headrest in front of him.

The lesson here is you are on a plane, people - NOT at home, and not at liberty to let your comfort make others uncomfortable.
