One person warned: "As a Senior Cabin Crew I tell you: Please, Please, Pleaseeee!!! for the love of God DO NOT, I repeat DO NOT even walk bare feet on an airplane floor, Even more, do not Dare laying down on it If you love yourself!!"
Another was more direct: "Yuck no!"
Even the man's choice of sleeping on the seats faced scrutiny, with one person saying: "Not even on the seat. You know how many strangers pass gas on those. Eewww!!"
Another wrote: "If I'm dying and they need to do some form of CPR, possible. Other than that, if I'm dying, I would rather jump out the emergency door, or just die."
Some frequent fliers could understand the choice, with one person noting: "When you are 20 hours into the 25-hour flight from Australia to the UK, the floor looks very comfortable!!!"
This desperation was echoed by another commenter who suggested the sleeping position was acceptable, with a small addition: "Those 14 plus hour flights have you doing things you'd never thought you'd do. I empathize. Granted I'd at least put down a blanket."
