I was originally thinking this and would have been very, very annoyed if it was the case as I have already changed my flights due to my original DXB-GLA flight being changed to a two class but I was able to re-select my seats in F on both flights.

Expertflyer also shows that the flights are operating with F (with the caveat that last minute substitutions can happen).

If they do sub either of the flights for a two class, then there will be a large number of very unhappy pax. The aircraft from DXB to PEK that will be operating my PEK-DXB flight currently has a high F & J load. My flight to GLA has only got one seat left in F.

I am just hoping it is an IT glitch or that because my DXB-GLA flight is on 2nd July is just throwing the website out a little.

Will call them again soon as the CS agent said to try in a couple of hours after I called and it is coming up soon.
