Not really a reduction on Dublin to Boston, there are currently only 7 weekly direct Dublin to Boston flights, the other 4 operate Dublin-Shannon-Boston. For Summer 2011, the Dublin-Shannon leg has been chopped (there are no longer any Dublin to Shannon flights scheduled) and Shannon to Boston has been reduced to 3 flights weekly.
Shannon to Boston and New York were not daily for Summer 2010. Shannon to Boston was 4/5 weekly and Shannon to New York JFK was 4 weekly.
One A330 aircraft will be based at Shannon for Summer 2011 and it will operate to New York M-W-F-S and to Boston -T-T-S-.
