The Aer Lingus summer timetable has just been posted. As well as the announced new flights to Munich and Stockholm, there are increases on the Altantic routes.
JFK is it's usual daily flight with an extra flight on fridays, leaving Dub at 14.00 and getting into JFK around dinner time, unsure if it's via SHN.
Newark is daily again, and Boston goes daily direct from Dublin and Shannon. Chicago is daily once again and LAX goes 6 times a week at its peak, Sun-Fri is the schedule with Sat the only day not included.
As expected on this site, the Washington flights are nowhere to be seen and the tactic was merely a plan to get the government to review the Shannon stop-over.
