I disagree completely. Fine print should not allow an airline to sell more of anything than they can possibly deliver. The practice needs to be outlawed or at least reformed to where the airlines cannot drag a passenger who has paid for a fare from the plane and leave them on the tarmac because it might inconvenience their profit making.
Fine print is no defense to being a scum bag and bilking your customers
They have set the whole sytem up so they can screw their customers with impunity. It's un-American. It ought to be illegal.
