Same problem for my flights in February GLA-AKL via MEL although I have been able to upgrade my GLA-DXB and DXB-GLA flights. I have set up an Expert Flyer alert but I also keep checking via Manage Booking. Fortunately I have enough miles for the round trip if only I can use them.

I read somewhere, maybe on here that it might be difficult/impossible, can't remember which, to upgrade the second leg of a multi leg flight at on line check in or at the first airport.

Have your GLA-DXB flights been changed to a 2 class aircraft? I have noticed this happened quite a few times in December 2013 and in another post for at least one forthcoming flight in January 2014.

Fingers crossed for unsold inventory on both our longhaul flights and no involuntary downgrade for me between Glasgow and Dubai!
