That would be nice, but I don't see how you could efficiently do it. Seems it would take 5 days minimum to do one trip.
Day 1: SFO-HNL, Layover
Day 2: HNL-NRT
Day 3: Layover
Day 4: NRT-HNL, Layover
Day 5: HNL-SFO
To run this service daily, it would take a LOT of f/as if one crew is going to be gone for 5 days. And, you've got to assume at least 3 days before they do it again. And, would any crew have to do it more than twice a month?
IORFA, are these assumptions correct? Could you shorten this scenario by doing SFO-HNL-NRT (or NRT-HNL-SFO) in "one day"? I don't know about the times and legalities. (In domestic, you know, if you can still stand on your own, you're legal.
) Also, even if you could do SFO to NRT with a stop in HNL, wouldn't this also take a lot of a/c to do?
