It may seem too late to start planning your 2018 Irish trip but with these amazing cheap flights to Ireland from the US available and our tips on when to book, you’ll find yourself along the Wild Atlantic Way in no time.  

Whether you’re looking for cheap flights to Ireland from New York, Boston, Chicago, Atlanta, Orlando, D.C. or LAX, there’s never been a better (or less expensive) time to fly to the Emerald Isle, with Spring and Summer sales well underway.

Remarkably, low-cost airline Norwegian Air is still offering fares from their base in Stewart Airport in upstate New York to Dublin from as little as $89 one-way and to Belfast and Shannon from $99 one-way during the summer months.

While these flights will rise in price as the weather gets better, flights to Belfast will jump up to a starting price of $249 one-way in August but flights to Dublin and Shannon remain at a starting price below $200 one-way.

For example, if you’re looking to get from New York to Dublin from May 15 until May 22, you can get a return flight still for only $241.40.

Even at the height of summer, however, return flights from Stewart to Dublin between August 8 and August 14 would put you back $425.90. While it should be remembered that these are very basic fares which don’t include a check-in bag or meals during the flight, it’s still worth thinking about for a last-minute Irish trip. These fares could also be availed of at an even lower price depending on your flexibility.  

Irish airline Aer Lingus also still have Spring fares available with prices as low as $385 if flying to Shannon from JFK.

As for the summer, flying to Dublin with Aer Lingus from 11 U.S. cities and to Shannon airport from New York JFK and from Boston, you can get a round-trip journey on the 4-star service airline for anything from $496 dollars if you're traveling between July 1, 2018, and August 22, 2018.

Flights from $619 will get you from Boston or New York to Shannon, while round-trip tickets from LAX are priced from $816.

With improved competition in the transatlantic market, the idea of a perfect cheap time to book a flight to Ireland is not as relevant as it once used to be. While the summer season, coming up to Christmas time, and approaching St Patrick’s Day will see fares rise, by signing up to Aer Lingus and Norwegian Air’s newsletters, in particular, you can hear about value fares as soon as they’re announced.
