Agree with Cloud1 and a number of other posters. EZY may be good for some but not everyone. As a frequent business traveller, and there are quite a number of us, the frequency of service is a big factor. Driving out a number of services with locally based aircraft will be a big issue with potentially a significant loss of regular red-eye and evening flights.
Whilst FlyBe had a poor reliability record when they moved in this has vastly improved, albeit it is not as good as when there were 4 based aircraft. It is also good that there is a good variety of destinations on FlyBe and I can't see EZY serving them all.
One of the winners could well be the BACF/Eastern service to LCY?
