I'm having a hard time selecting 2 seats on JAL route
NRT-HAN AA codeshare, JL operated Economy seat on a 787-900
EF show row 47 available, and bunch of rows that are blocked (46, 46 and 51 to 55), AA can not see 47, so I have to select the last 2 seat available on row 51 (middle seats).
I tried to call JL US, no answer, JL AR same thing, lnly JL MX answered but they were unable to touch/select seats because is an AA codeshare. I didn't have a problem with SGN-NRT on a 787-800 on the same PNR.
