No, staying where I am. CO was very good for me all these years. I wished they'd merged w/NW instead of UA, but it didn't happen. UA flies where I need to go (SE Asia 6~9x per year).
The hiccups some are experience (I've had NO issues whatsoever) since 3/3 are going to be resolved & will soon be a distant memory.
There are a few things I'm unhappy with but none are going to make me move.
