For me, EZY is the worst place of the majors (Ryanair, Vueling, Norwegian and easyJet) -LCC's.
Ryanair has scale, while Vueling has great access to Primary airports and the backing of IAG. Norwegian has pushed a long haul strategy which seems to be working for them, and wifi on short haul.
EasyJet - apart from having strength in some primary airports and markets has little uniqueness now.
22/04 - I thought about this recently with Monarch. They have the extra legroom at the front which could be marketed a cheaper version of business class (or Crown Service) - I think there is a market for it.
