To explain why you not thinky with full brains: Airline seats are a commodity. Tickets are contracts. A ticket is a futures contract. To allow the seller of the contract an out is fundamentally unfair to the buyer. The Universal Commercial Code 400 (UCC400) fully addresses this. Saving a Force Majoure situation the damned airline better give you the damned seat you contracted for.
Well then we can both follow Coulter’s upcoming lawsuit against Delta Airlines.
