hello; Bumping is done a lot more than I had thought. (from the link I posted a while back.) It seems like poor business but it is within the law and the fine print of buying a ticket. Not just this airline, but as I understand all airlines.Just image if you are on a plane and you have to be somewhere in a few hours then they tell you to get off and wait until the next day... just to let an employee to take your place.
I see your point but it is the rules. Those getting bumped are well paid for the inconvience.
