I am departing FRA this evening on EK48 (FRA-DXB) and then continuing onwards to Auckland on EK406 (DXB-MEL-AKL).

I wish to upgrade my last sector of travel (MEL-AKL) using miles, however I have been told by the EK ticketing desk at FRA that this is not possible, because the two sectors of EK406 have been booked "combined".

I previously made a thread here asking about this type of upgrade, and was told that it should be no problem.

I'm wondering if there is someone who has been in this situation before? Is there perhaps somewhere in DXB that could process this request? Otherwise I will have to try my luck doing the upgrade on the aircraft.

Thanks!
