Hi all,

I read that from 01.01.2015 the route AUH-GRU will be perform with a Boeing 777-200LR.
When I bought the tickets (months ago) I choose my seats on EY website on the map showing a 777

I reserved my limo and received a new confirmation stated the aircraft will be an Airbus A340-541

How can I change my seats (I'm travelling in C)? When I choose them there were in "the middle of cabin", now I'm on the back, near galleys and the beginning of the Y cabin. As I will fly with my little son I would prefer to stay farther from noise (from the galleys).

Thanks in advance
