On the topic of JL availability, does anyone know why a JL flight that appears to be wide open (D9) both on EF and to the AA RTW desk would come back "unconfirmed" every time they tried to book it? I've been trying to switch from JL38 to JL36 for months with no success, and with the departure date approaching (February) the situation seems unlikely to improve.

I suspected it might be a POC thing but that doesn't explain why the agents are seeing availability only to then fail to book the flight...
