EI-BUD
How do you think Easy will do 3 daily if BE stop? BE do 4 daily with half the capacity on each aircraft, not forgetting they weren't even 3/4 full before Easyjet. Therefore max is likely to be 2 daily with a poor schedule as peak slots will be used at LGW for more lucrative routes.
As I've said before IOM may regret Easyjet's arrival longer term, great cheap fares in the short term though.
