Well Aer Lingus
promised when all the uncertainty over the shannon-stopover arose that they would keep at leat one flight to Boston and New York at SNN. Not sure if they'll keep that promise though. But in fairness, making the rest of the country trek to DUB to catch a T/A flight when they've been used to being able to just go to SNN , I believe, would be a bad move for Aer lingus in terms of goodwill and loss of business.
