Got to say, I've been fairly happy with the combined airline, but I was forced to fly both CO and UA regularly even pre-merger so I've gotten a lot of perks with EUAs on CO. Will hit 1k this year, and while kinda annoyed about the CR-1 reduction and other issues, I've had no issues clearing international upgrades with miles, and I look forward to another year of COUA flying.

That being said, with my move to PBI at the end of this coming year, I might be on AA like it or not :-/.
