I'll have to see what they say when I check in at NRT tomorrow morning.
Currently in SYD starting a combined DAS13/DONE3 oneworld RTW holiday.
Total of 4 tickets on the holiday, they had all been booked together under the same PNR, but the PNR was split into 3 when the tickets were issued. So my next 3 flights (SYD-HND, NRT-JFK and JFK-BOS) are each on a different PNR.
While I'll still have to collect bags at JFK, clear CBP and move to T8, if JL issues the AA pass to BOS, it's one less thing to worry about when I get to New York.
