"I have a JL flight ticketed. I want to add another JL segment (same class, same date).
The seat is available for booking with a new PNR.
It's coming back as unbookable in to the existing PNR. Super helpful AAgent tried her help desk and the OW desk. It kept coming back UC instead of SS (whatever that means) and couldn't push it through.
Any thoughts?"
Same situation.
ORD-HND in F, can't add BKK in PE... keeps coming back unconfirmed.
