My question is this: how flexible will UA allow us to be in order to preserve the correct connection ex-HGH? I arrive via HKG, and my original flight, as you know, was HGH – SFO. Will UA agree to a tortured routing with a stop in NRT or TPE so that I can still qualify for the visa? Alternatively, I could return from PVG, but then I don't want to arrive HGH; I have so little time to sightsee as it is, I don't want to waste any time transiting in between the two cities. Will UA allow me to change the whole tickets to come in to work and leave out of PVG, or is that pushing it?
