What do you bet it will be for one of those high density 2 class 615 seaters.
Unlikely but you never know. I think F operates at around 60% so no bad on 777 but if they did send two class IMO it would be the odd peak season service however two class 777 is very common during summer.
I know nothing about when they plan on brining it but they have requested it so it is coming at some stage.
There will be the contact stand as well as a remote one available. Lot's of planned apron reconstruction work happening between pier 3 and 4 which is taking over 6 months so likely until May before A380 will be allowed operate.
