Its going to be fascinating to see how this all works out.
Easy have seen the opportunity giving them extra coverage of London and the south east and obviously got a good ten year deal.
I doubt ryanair would be too worried but it will raise a question about their dominance at STN and nowhere else in the region.Easy have stole the march on them at Luton, Gatwick and now Southend in terms of based units and destinations.
From a catchment area perspective in my opinion STN is in a weaker position than its competitors.My flights from there are because i have no other viable alternative and many regular passengers on my flights find themselves in the same position.If and when that changes,well thats another question.
(STNs advantage though is it has flights to the more remote/ local destinations served by Ryanair )
I suspect Easy will just choose the high density routes from SEN( cities and Holiday spots) but even so interesting times ahead.
Good luck to all involved
