Does crossing Zones on a partner triggers Partner Pricing even when major transoceanic segment is on UA?
SFO-NRT on UA, then NRT-PVG on NH costs 80k (which "should" cost 70k IMO)
but
SFO-TPE on UA, then TPE-PVG on BR costs 70k
NRT and PVG are in different zones whereas TPE and PVG are in same zone.
