There's a fair bit of business traffic between the two countries and lots of tourist traffic both ways, which is particularly high end in the BKK-TYO direction (HiSo Thais love visiting Japan).
HND or NRT, though?
Anyway, I think we’re actually saying the same thing: neither one of us thinks that UA is likely to add an NRT-BKK flight.
If they were to add that flight, then they would be competing directly against their JV partner for intra-Asian travelers, and they’d have to share revenue with them on connecting travelers from the US. UA has to know that a GUM 737 isn’t going to be an attractive-enough option for intra-Asia travelers to be worth the angst, and a 787 is more useful to them operating out of SFO. That’s why I deduce that
if they were to add that flight, it’s likely that it would be a replacement for an NH flight — because that makes more sense than head-to-head competition does.
But it’s an exercise in conditional probability.

I do
not think UA NRT-BKK makes much sense. If UA were to add a new NRT destination, I’d expect it to be to a destination that NH does not serve.
