I just tried to check in for my tomorrow-morning flight and it just returns an "error" page. Strangely, the itinerary shows no date in the "Current reservations" list, though the receipt is correct.

So I called the 1K line and have been waiting on hold for half an hour. So far, not a great experience with the new consolidated United!

I'm assuming they'll work it out. But I get nervous when it looks like my reservation is screwed up!

Update: Almost an hour on hold now. Yeah, the 1K line is just amazing! Not sure if I should hang up and try again...
