Same thing happened to Aer lingus with three longhaul A330 aircraft all going tech in july and August simultaniously.
Its just the luck of the draw. Its a real pity Epsilon does not not have the ability to operate out of pembroke dock.
The real hero to come out of this is the Swift. She has performed very well helped by the good weather and last night took the passengers, cars and possibly the eurolines coaches to holyhead on an additional 0830 - 2230 DUB - HLY and 2330 - 0120 HYL - DUB Sailing.
