Hi all, first time posting!

I'm travelling on EK from GLA-MEL later this year so have been keeping an eye on their services from GLA-DXB. It seems to me that the Glasgow route (EK25/26 and EK27/28 - see below) receives a disproportionate number of the older B77Ws (registration A6-EB*) with the older IFE and seating, which AFAIK are not planned for upgrade in the near future. Certainly compared to other routes in Europe and other regions, even short hops in the Middle East, Glasgow seems much less likely to receive a "new" B77W.

Is there any reason for this, or is it just my imagination?
