Thanks for sharing the information.
Unfortunately, I just tried setting this up and it doesn't seem to know when miles expire. For my USAirways account, it is showing that my miles expired last November and I don't see a way to correct that because it logs into my account at USAirways and retrieves the info.
For my United account, I had to enter all the information manually. Fortunately, I could retrieve the information from my AwardWallet account which seems to know everything and is correct.
I think I'll stick with AwardWallet unless I'm missing something.
