Good question. A gentleman read my suggestion (not here on FlyerTalk) on the Operational mooch off of
Suzy1K's getting 2 Economy seats for 1 person deal. I know he was successful getting the 2 economy seats for himself, no problem. But I never heard back from him on the "2 of mine, for 1 of yours" upgrade mooch.
I'll email him and try to find out how it went.
Thanks for the reminder!
