I've had AwardGuard for a number of years. (Until a couple of years ago, I was carrying a hefty number of TWA equity miles and wasn't sure I'd get to use them before TWA expired. Even after I used those, I still had substantial non-equity miles on TWA and so kept AwardGuard.) Ironically, I almost let it go this year in view of the AA acquisition, but decided to keep it one more year and monitor US's condition. Now I'm glad I did.
