EIN promise they're exisitng capacity post stopover to JFK and BOS.... Presumably they will base 2 or 3 A332's here....
I fly COA to EWR ex SNN all the time. Its always full.......They'res (And DALS, USA's,AAL's) service is so much betters than Aer Lingus, they are going to recieve more than theyre US compeditors. Aer Lingus are not what they used to be.
In a statement some time ago from Aer Lingus they said '...we currently supply 400,000 seats per annum on SNN Short Haul. We would be happy to increase this to 600,000. We are constantly keeping Shannon short haul under active(?) review.....' (Personally I dont believe this)
