Belfast Airport does not close at midnight so it is easier for Easyjet to keep its mainland UK customers happy by redirecting, generally on time in-bound Belfast aircraft to other UK destinations - never mind the poor Northern Ireland traveller.
I hope the author has the operational facts to back up this assertion..? Where are these 'on time in-bound Belfast aircraft' being redirected to? Do they have the fuel to get there? How will the crews manage an unplanned nightstop? Where are these critical network night curfew airfields that easyJet operate to? What a load of twaddle.
I am guessing the good people of Northern Ireland would rather keep easyJet than revert to BA only as they seem to like direct scheduled low cost service to:
Paris
Amsterdam
Alicante
Bristol
Edinburgh
Glasgow
Liverpool
Gatwick
Luton
Stansted
Malaga
Newcastle
Nice
How many seats a day is that? 10,000+ ? One company has come along and put more airline seats in and out of N Ireland than all other carriers ever have combined.
Methinks he doth protest too much.
