Anyone who's been on a lengthy flight has probably wished for a bed — and while you won't be moving, you can fulfill your plane-sleeping fantasy aboard Jumbo Stay. Built inside a decommissioned 747 jumbo jet that's now permanently parked at Stockholm's Arlanda airport, it offers a number of room categories — some that have a private washroom, some that access shared shower and toilet facilities, some that feature quad dormitory beds, and a luxury suite that occupies the converted cockpit and provides panoramic views of the airport. The only downside? We don't think this counts towards the Mile High Club.
