"Southend is largely a sideshow and the role of Gatwick is a lot more significant in drawing airlines away. EasyJet started cutting back at Stansted before opening a base at Southend and other airlines have also cutback or closed at Stansted. In Britain easyJet obviously sees the best prospects at Gatwick, Manchester, Edinburgh and to a degree Bristol. They will get expansion. Stansted and Liverpool are likely to get cuts."
Its interesting to see that the airports where easyJet see their prospects - Gatwick, Manchester, Edinburgh and Bristol are places where Ryanair have less of a presence. Compared to the airports where Ryanair have a large presence Stansted ,Liverpool(an exception to the rule), Birmingham and East Midlands etc where easyJet are either cutting back or have a very little service or nothing. However Liverpool is an exception as easyJet are of a reasonably large size and will be fairly stagnant there and easyJet and Ryanair seem to get on quite well here.
