I'm travelling HKG-TYO-HNL in J on an AA issued ticket. HKG-TYO is on JO and TYO-HNL is on HA. I am OWE. My understanding is I can access the OWE lounges in HKG since the first flight is on JO however at NRT I can only get into whatever lounge HA uses for J since I'm not flying a OW partner. Is that correct?
I assume you mean you are flying HKG-NRT on JL and NRT-HNL on HA? If so, then you would have Oneworld lounge access in HKG; and as you surmise, your lounge access at NRT would be whatever HA provides.
