"Ryanair also proposed standing areas on its fleet in 2010. At the time boss Michael O’Leary described the standing seats as “bar stools with seatbelts” and expressed doubts that seatbelts were even necessary. “A plane is “just a b----- bus with wings”, he said, “If there ever was a crash on an aircraft, God forbid, a seatbelt won’t save you. You don't need a seatbelt on the London Underground. You don't need a seatbelt on trains which are travelling at 120mph.”
Civil Aviation Authorities disagree however, and vertical seats have not been approved by regulators in any country so far. This may also prove to be the case in Colombia. Civil Aviation Director Alfredo Bocanegra told RCN radio that he does not approve. “People have to travel like human beings,” he said. “Anyone who had ridden on public mass transport knows that it’s not the best when you’re standing.”"
