But would EasyJet really want to encroach on current routes flown by Flybe rather than concentrating on unserved routes, I don't think it would be in the airports interests to have two airlines competing on the major domestic markets such as EDI and BFS.
IF and a big IF, we're EasyJet to announce flights from Southampton a scenario could be by a W pattern from other bases as others have suggested to at least test the market.
