Great idea, and i'd love for this to happen. It's always felt so unfair that you can't resell plane tickets. Like all the stupid shenanigans they do to overbook etc. banking on the fact that enough poor sops are gonna be out $500 because they broke their arm or something. I don't get exactly why companies would do this instead of just forcing the customers to eat shit if they can't make it. That's what theyve been doing and it seems to work. From their perspective, an empty room is even better than a resold one because they don't have to clean it. Also, why would this need to be on the Blockchain? Since the property itself is centralized it seems like they could do it with one database somewhere instead of with all the cost & gas fees. If they were gonna screw with it they could do that anyways even with a NFT by just not honoring it
