I must have missed this but if true I guess the routes where F is profitable / worth it could be moved to LHR and swapped with marginal 3 class routes. People always say Bermuda is a profitable route. I could see maybe 3 or 4 routes moving to Heathrow with perhaps 3 or 4 moving the other way, perhaps where there is 'duplicate' capacity. Or, maybe F isn't that profitable anyway so will just be dropped altogether on these routes. As I say, haven't seen it formally announced that no F from Gatwick.
I'm surprised Gatwick hasn't moved to a 787 Fleet.
