Very helpful, number_6! I've heard mixed reviews of air china J, and I worry that if there is an issue being in China will not be easy from a medical perspective. I think minimizing travel time is important, otherwise the QR would be a good bet.

HNL on the A330 seems okay, better than Jetstar J. That HNL immigration is a pleasure is actually very helpful intel - I suspected this would be the case.

Re: walking, I wonder if we can ask for assistance from the carrier. A wheelchair may be a bit much, but between pregnancy and J class, HA may be open to helping us out?

HA and UA tickets both seem to be fully refundable, which is good, as well.
