Can't see EI taking up long haul from BFS
If Continental cannot make it pay with their hub at Newark offering a multitude of connections, I don't see what incentive EI would have to operate to JFK or BOS. I know they could offer interline but it would compete \ take some sales from their DUB services and incurr a cost of £60 APD for customers.
If more than 1 person travelling in a group £120 becomes a big incentive to go down the road.
