When you sit on that plane and feel for the sick bag, think again. Online auctioneer eBay has a section for unused sick bags from almost ever airline around the world, described as being in “mint and very fine conditions.” There are dedicated Web sites, including the Air SicknessBag Virtual Museum, which has bags from airlines, trains and ships — and even some from outer space. American Steven Silberberg, who runs airsicknessbags.com says: “I don't use them for their intended purpose, I just leave them at home in binders… most expensive bag I've ever seen sold was for $220. It was a Court Line Aviation bag, a company that folded in 1973,” he told CNN. Scandinavian bags are highly prized for the artistic impression on the bags where US airlines have plain bags.
