I'm surprised Easyjet couldn't have replaced the Gatwick service with a service from their main base at Luton, meaning they wouldn't be in direct competition with Ryanair. I suppose they reckoned that Ryanair would start a Cork-Luton Service just to spite them.
Easyjet's problem was that their fairs were similiar to AerLingus, without the convenience of Heathrow. I flew from Cork to Gatwick with Ryanair at the weekend and the return flights were both full. Ryanair are obviously doing very well on the route even with Easyjet still here. Will they be able to absorb all the three flights daily Easyjet Traffic with one single morning flight?
