I wish they would just make it similar to the resort credit - $250 off any airline purchase - the resort can be room, or restaurant, or spa, or cabana, etc...just any money spent at a resort.

Restricting the airline credit to just peripheral spend (upgraded seats, baggage fees, etc.) makes it very difficult to use for those of us who primarily fly one airline but already get the seats they want and checked bags for free. It forces people to do "tricks" to get the credit, and for saps like me who don't want to do that, I leave some credit on the table almost every year. Why not just make it $250 off any airline purchase....sure, most will end up with a free flight or two, but they're already giving us a free hotel room, what's so terrible about a free or close to free flight, or a small chunk out of a very expensive flight?
