the singlefleet operation works at LGW beacuse we do short-range longhaul that checks in the morning and all clears by the latest 10:30 in the morning. Also its a smaller base with a lot less crew than LHR and we have a bid system that can almost give us what we want.
Having a singlefleet operation at LHR becomes more complicated because of the varying destinations/times zones/check in times and when you factor in long-range trips such as sin-syd. I cannot see having the whole of LHR on a singlefleet operation with a bid system working ???
