I’m flying JAL (as you probably know) in August from HND to SFO. If I have the option to switch to JAL 1 (which is two hours longer and I def want to maximize the flight), instead departing SFO, would you do that? The lounge and catering ex HND seems to be better. Would a JAL J ticket warrant Oneworld lounge access at SFO (CX, BA, etc.), or is it limited to the Sakura Lounge at SFO? If the latter, then I would for sure stick with JAL 2, but I’m interested to see what you think.
@ Sam — Yes, you could access any oneworld lounge. The flight is basically a redeye in both direction, so I’d do whichever is more convenient for you. A bit confused as to how SFO-HND is a substitute flight from HND-SFO, though. :p
