The risk in using a Dublin based aircraft, Jamie, is that it's very easy to drop a rotation and to use it for other destinations.
Any reduction would happen whichever base is operating, I expect the increase capacity to LPL/MAN/BHX to be cut peak seasons both sides of the water.
Anyway its Aer Lingus forcing their hand in regard to schedules.
In fact you may even see a lot of the UK capacity start to fall away early 2016 like happened earlier this year.
