The interesting thing for me here is how they'll manage upgrades. On AA, you can usually buy F right up until departure (i.e., they don't fill it with upgraders at the windows). US isn't like that - if you need to make a change within the upgrade windows, you can kiss your seat in the front of the bus goodbye.
That's a major difference for me since I tend to book close in and often have to make changes.
In theory, if they integrate FFPs realtively quickly, this benefits me as I wound up just missing CP by 6 segments and 5k miles, landing at 114/95k. On AA, I only did about 40/40k. Combined, it's fat city. Heck, if they just stick with AA's segment requirements I'm golden.
... also makes the 1k comp and subsequent 25k of January flying look even dumber on my part than it already did.
