I have a problem with QF system and my current DONE5 ticket. I can't check the booking at QF website, add the seat or meal reservation to QF segments, even on the phone. Tried phoning to AA and QF with no success with seat or meal reservation.

QF agent said, that the problem is caused by multiple e-ticket numbers on the same ticket, according to him, their systems support only one e-ticket number per booking reference.

I made two changes before on the way, thus my e-ticket got reissued twice. The old e-ticket numbers still appear in the booking. Moreover, latest e-ticket number appears twice, with 15 digits for non-QF segments and with 13 digits for QF segments. Also JL segment does not have the e-ticket number attached at all.

Ticket is issued on AA stock by AA RTW desk. According to AA RTW desk, they need to keep old e-ticket numbers attached to booking and my booking should be ok now.

Week ago, QR cancelled one segment because no e-ticket number was attached. Luckily, there was still availability and AA PLT desk was able to fix that, but she needed to manually call to QR to confirm the segment, so that QR won't cancel it again.

So how those e-ticket numbers really should be in Amadeus? Any ideas, what to try next to get the issue fixed, as both AA and QF are saying that issue should be handled with the other airline? Would it be safe to get the old e-ticket numbers removed from the reservation by other airline than ticketing airline?
