I posted this in another forum and was told I might have more luck here. I'm trying to make a decision about a trip in December and right now it's a toss-up between going to Shanghai or Hong Kong, so the airline/aircraft may tip it one way or the other. Any insights about which would be better for the transpacific portions of this trip in economy would be appreciated:
Air Canada 767-300 to PVG vs. Air China 747-700 to HKG
