Calling NH probably won't help (unless I want to pay the change fee and difference in fare, which is substantial). I wonder if UA would be willing to move me to a flight the night before? If they do not, and I misconnect, they'll have to get me to HKG which is a lot more expensive for them, presumably?

Can they do that on another carrier's ticket? Should I even try? Or am I stuck rolling the dice and waiting?
