Thanks jbalmuth and allset2travel for the additional extremely helpful details!
I'm having trouble finding JFK to HKG on partner airlines via ba.com. I tell the search to include partner airlines, but it keeps only bringing up flights that go through LHR, and none via TPAC. Any ideas about what I might be doing wrong?
