Easyjet will do what they want unfortunately... And what they want is to have as many aircraft as is humanly possible in the South East.
With No APD I'd hope EZY could reinstate a London route and hopefully we might see a resurgance from Bristol and to a lesser extent Belfast.
Hopefully BE to STN will be fruitful but timings aren't brilliant, I reckon Ryanair could fill 2 738's a day to Stansted though if they offered the £9.99 all in fares they do from Edinburgh and Glasgow.
