If the arrival of easyjet means BA pull out of LGW then presumably they will move everything including longhaul. As a consequence everyone will feed into longhaul at Heathrow. That will leave a few US carriers and Virgin doing longhaul out of Gatwick. Since peoples main focus for longhaul would then be LHR,LGW then becomes a provincial airport again with a lot of capacity and only shorthaul. This talk of lowcost carriers pushing out the established operators who do longhaul flights could end up "poisoning the well" so to speak causing a reduction in passengers who actually want to travel through Gatwick. The only thing LGW has going for it is it's 30mins by train to London.
