Airlines will usually be happy to sell you more than one seat for your trip although they really don’t advertise it. One woman, with three seats to herself, felt that wasn’t quite enough and decided to build a fort. A FORT. She turned her row in coach into a business class suite with walls, using plastic wrap. She even gave herself a roof while a passenger across the aisle from her filmed the pre-departure construction project. … A crewmember finally came over and started to tear down the house, letting her know that it wasn’t permitted. He threatened to have her detained, while she yelled for help. After her plastic wrap home is demolished, the passenger threatens to rebuild it — pointing out that she had a “backup” roll with her.
