A Pilates instructor’s wild in-seat stretch on a 10-hour flight has the internet divided: is it genius self-care or a total space invasion? She claims her tailbone was killing her, so she propped her legs straight up the cabin wall (with flight attendant approval!). Some say it’s gross and inconsiderate, others swear it’s necessary for survival in economy. Would you risk the side-eye for a little relief? What’s your go-to trick for surviving long flights? #Fitness #TravelDebate #EconomyClass
