My thoughts: it's too early to tell. My guess is that CO will merge with someone and leave SkyTeam. But, if they don't merge, then there's no reason for them to leave (that I can tell). The NW/Delta merger probably won't be effective until near year end. And it will take a while after that for them to merge. So, unless CO merges quickly and leaves SkyTeam before the end of the year, I think things will remain pretty much the same for the next 12 months. Until it's clear what CO is going to do, there is just no reason to do anything.

If CO merges, I'm planning to switch back to CO.
