Flights to Dublin from the US: Nonstop Routes, Flight Times and When to Go

Airlines flying to Dublin from the US

Aer Lingus, Ireland's national airline, flies from more US cities than any other airline: Boston, Hartford, New York JFK, Newark, Philadelphia, Washington Dulles, Pittsburgh, Cleveland, Raleigh-Durham, Chicago, Indianapolis, Nashville, Orlando, San Francisco and Los Angeles, plus Miami and Seattle in season and Las Vegas until 3 December 2026, as of recent schedules; check with the airline.

Delta flies from Atlanta, Boston, Minneapolis and New York JFK, United from Newark, Washington Dulles and Chicago, and American from Philadelphia and Dallas/Fort Worth, with more in summer. Aer Lingus is part of the same airline group as British Airways and Iberia and partners with United and JetBlue, so one-stop connections are easy to book on one ticket.

US preclearance on the way home

Dublin is one of the few airports outside the Americas with US Customs and Border Protection preclearance. On a nonstop flight to the US you go through US immigration and customs in Dublin, in Terminal 2, before you board, and you land in the US as a domestic passenger.

That saves time on arrival, especially if you connect onward, but it adds a step before departure. Allow extra time at Dublin Airport for check-in, security and the preclearance queue.

Best time to visit Dublin

May to September is the mildest and brightest time of year, with long evenings in June and July. It is also the busiest season, together with the days around St. Patrick's Day on 17 March and the weeks before Christmas.

November to February is cool, damp and dark by late afternoon, but the city is quieter and the pubs, museums and theaters keep it lively. Rain is possible in any month, so pack a waterproof layer whatever the season.

Entry rules for US citizens

US citizens do not need a visa to visit Ireland, and Ireland has no electronic travel authorization, so there is no ETA to apply for. The immigration officer grants permission to stay, normally up to 90 days for a visit. Bring a passport valid for the whole stay, and be ready to show your return ticket and where you are staying.

Ireland is not part of the Schengen Area, so the EU's Entry/Exit System does not apply at Irish borders, and time in Ireland does not count toward your Schengen 90 days. If you cross into Northern Ireland or travel on to Great Britain, US citizens need an approved UK ETA, even though there are no passport checks at the land border.

Getting from Dublin Airport into the city

Dublin Airport has no train link. Dublin Express coaches run through the Port Tunnel to the city center, Aircoach serves the center and south Dublin, and Dublin Bus routes stop at both terminals. Most take about 30 to 45 minutes to O'Connell Street or the city center.

Taxis wait at the ranks outside Terminals 1 and 2 and take about 25 to 45 minutes to the center, depending on traffic. Aer Lingus uses Terminal 2, which is also where US preclearance is, so most transatlantic travelers arrive and leave from there.

Time difference and jet lag

Dublin is 5 hours ahead of US Eastern time, 6 ahead of Central and 8 ahead of Pacific for most of the year. For a few weeks in March and around the end of October the gap is one hour shorter, because the US and Ireland change their clocks on different dates.

Most flights from the US are overnight and land in Dublin early in the morning. Hotels may not have your room ready, so plan a walk and some daylight before an early night on local time.
