Don't expect to see easyJet on LGW-ORK....it just ain't going to happen. Not for now, anyway.
easyJet want to mximise the number of turnrounds through each airport on their network and, to a large extent will concentrate on routes out of LGW that are already on their network....great economies of scale, handling infrastructure already in place, etc. Not only would ORK be a new city, but it would be an entirely new country, with no established marketing support, etc.
LGW growth over the next year unlikely to cover any stations which aren't already on the network.
