Few years ago we were on VS022 from IAD to LHR and after boarding the CC came on and wanted volunteers to give up their seats, overbooked??
How on earth can this happen?? Surely they would know about overbooking at check-in, and deal with it there - are you saying that they actually checked too many people onto the plane? That would sound like an incredible display of stupidity! Is there any sensible explanation for how this could happen?
