6. Being too sexy
Too sexy for your shirt? Several airlines have clauses within their “contract of carriage” that allow them to give you the boot for wearing scandalous outfits.

In 2007, they removed a college student for her short skirt; in 2011, they refused to transport Green Day front-man Billie Joe Armstrong because his pants were too saggy; and last year, they kicked off a woman because her cleavage was deemed “inappropriate”.
