I am due to fly next month from CPH to BKK, via DUS and AUH.
Ticket issued by Etihad.
Legs CPH - DUS and DUS - AUH are operated by AirBerlin.
Ticket bought through travel agent.
Category booked E.Had i known this before paying, i would never done it.
I need to fly in any of the following classes : HKLMSV, which will give me 20 Q miles, enough to atain Gold status within Qatar's Privilege Club.

So i need to upgrade the booking category.Is this even possible?
Maybe i should contact Etihad, since it was them who issued the ticket.I decided to skip the travel agency who expects me to pay at least 350 euros in fees.

Does anyone have any suggestions?

Thank you and Merry Christmas.
