American:
Best - MRTC when you don't get the C/J/F cabin. Upgrade Any Fare. By far and away the best thing about AA. Good alliance partners. Ability to sidestep no double upgrade policy by paying fare difference from C/J to F. Access to other OW members' clubs for Plat/EXP/Admiral's Club members.
Worst - No double upgrades (for the most part). No free drinks in the Admiral's Club, despite insanely high membership fees. Difficulty in puting together multi-segment (3+ segments) flights. Having to plead for mileage credit when reaccommodated.
In my opinion, the AAdavantage program is the strongest in the nation at the moment as far as what's important to me. I am going to shift my travel accordingly.
