Not much to add. We quit travelling so much but still use cc and it is the best out there. They send them randomly as I don't use then anyway and also used to have so many with no expiration that I couldn't give them away. They do seem to have gotten less frequent since the expiration date. Maybe they changed with the change from segments to points as well. I wish they would go back to the old system but it still beats any other airline hands down.
