g.f.
Since US west coast to PHNL is the conversation here, returning to departure or continuing to destination is pretty much the same thing.
Aterpster:, yes, KSBA to PHTO is the shortest and might be a better example but not a lot of difference
KSFO to PHTO is 2,013 n.m.
KSBA to PHTO is 2,065 n.m.
As I said previously I only flew KLAX-PHNL-KLAX.
Once KSFO became closer than KLAX we were to divert to KSFO prior to the ETP. After the ETP we were required to divert to PHTO until PHNL became closer than PHTO.
