What Do We Hate Seeing Most On An Airplane?

The results are in, folks, are you ready for this?  A new survey was conducted by the travel search site Skyscanner and the number one thing that offends passengers on airlines is the sight of...

butt crack due to ill-fitting clothes, careless bending over, or -- in some cases -- on purpose. The fleshy phenomenon was regarded as even more distasteful to fellow passengers than sweat stains on clothing, beer bellies on display and offensive logos on t-shirts. Other flying fashion faux pas, were white socks and sandals, ladies with low cut tops, and men with hairy chests on display. The survey was taken after an American woman was refused entry to a Southwestern Airlines flight because staff thought her exposed cleavage was inappropriate.
