Stand 30 is being modified for A380 ops, this has been planned for a while it seems. As for the return to the B777, that’s likely dependent on how well EDI and GLA work alongside each other. Continental (later United) started off being GLA focussed building to DC10s then opened EDI, split GLA/EDI biased to GLA, then biased to EDI, then GLA dropped to seasonal. There is a comparable structural weakness in the inbound market on the western side now. Only time will tell, I suspect they are keeping their options wide open.
