What kinds of carry-on items don't get carried off airplanes? A wedding dress, bag of diamonds, prosthetic leg, glass eye, underwear and handcuffs, for starters.
Crew members from 83 countries surveyed by online travel booking site Skyscanner reported finding different animals -- a parrot, frog, falcon, tortoise -- as well as random items such as a box of dried fish, a wig and a toupee, even a written marriage proposal.
Of course, more mundane things get left behind too. Of the 700 cabin crew members surveyed, 24% said they found passports, 23% found cellphones and 21% found books.
Lost items can be overwhelming for airlines too. U.S. carrier Southwest Airlines says 10,000 to 13,000 items are turned in to its lost and found office every month, a newspaper reported earlier this year. Cellphones and reading glasses topped the list of items left behind, most often in the seat-back pocket of the airplane.
