I don't see why they can't announce the exact date if one exists. I suspect they're having integration issues between reservation systems and are not able to predict this yet.

Either that, or the merger work -- due diligence, regulatory paperwork, oversight by legions of lawyers, etc., has pushed this to the backburner.

Leaving tomorrow on a UA trip... had to pay for E+ despite being CO Gold, I hope for the last time. (But at least they have an E+ option which CO doesn't).
