Do you think when these planes come online they might be used on shorter hops around the UK for training sectors, such as AF did with their A380 flying CDG-LHR? Holding on to a pipedream to fly one or both of them GLA-LHR.
There are plans to operate the A380 and 787 aircraft on shorthaul routes as training sectors. The list of which destinations these will be is expected to be released in the next month or so.
Personally I think the A380 will be used for training sectors to CDG, FRA or FCO. With the 787 likely to operate on the domestic 767 sectors of EDi and GLA.
