that is bollocks. Never worked or works like that. Passengers get checked onto planes first come first served, overbooked or not. When a plane is overbooked the late comers generally get fuxxed. That is how every normal airline handles that (those that have the guts to overbook to start with).I have never in my entire life witnessed passengers removed from within the airplane because the airline overbooked. Its outright ridiculous to even accept that as the slightest argument in favor of the airline.
Yes, OMG. Selecting who to remove randomly ? Seems fair enough at first sight. But look closer, and maybe there are other factors at work, as other posters have noted. Maybe you randomly selected someone who is dealing with a life or death situation.
