Delta flights between Philadelphia, Chicago, and Boston and Ireland are available for less than $350 roundtrip. Fares are available from September through May excluding peak holiday dates. From Philadelphia you can fly into Dublin or Shannon, from Chicago and Boston the fares work to Dublin.

Find your trip using airfare metasearch site Momondo. I’m seeing the best fares are Air France codeshares on Delta flights.
Remember not to credit these tickets to a Delta SkyMiles account, they’ll earn about 1200 miles roundtrip for a non-elite member. You can earn 50% of the ~ 6500 flown miles crediting a ‘V’ fare to Alaska Airlines Mileage Plan.
