Pobeda, budget Russian airline has banned chewing gum. Passengers are no longer allowed to chew gum on board because it costs too much money to scrape dried chewing gum off of the plane's interiors. Andrei Kalmykov, the airline's CEO said it costs 100,000 roubles, or $1,700, to remove one piece of gum.

Gum isn't the only problem the airline faces. Kalmykov was also quoted earlier this month saying that passengers have stolen thousands of dollars worth of equipment form the planes, including life jackets and safety instruction cards. Maybe they were just using the using the safety cards to wrap up their chewed gum.
