But if EZY, MON,FLYBE etc etc Move to Heathrow, Gatwick won't need a second runway. ...
I believe that EZY have said that any flying from LHR would be complementary to that at LGW. BEE only fly to NQY from LGW these days, so that would also be complementary and they have openly stated that they are looking (although I can't see it in reality) at operating from NHT if they can't get into LHR.
Meanwhile, I expect Boris feels like being on an "island" far away right now.
