Hartford to Dublin Flights (BDL to DUB)

Yes, you can fly Hartford to Dublin nonstop. As of November 2026, Aer Lingus flies between Bradley International Airport (BDL) and Dublin (DUB), and as of recent schedules it is Connecticut's only nonstop flight to Europe. The flight takes about 6 to 6.5 hours eastbound overnight and about 7 to 7.5 hours back. In recent winters Aer Lingus has paused the route for several weeks in January and February, so check the airline's schedule if you plan to travel in midwinter.

Who flies Hartford to Dublin

Aer Lingus operates the nonstop with a single-aisle Airbus A321neo long-range aircraft, which has lie-flat seats in business class and a standard economy cabin. Frequency changes by season: daily in the summer peak in recent years, fewer days a week in late autumn and early spring. Treat the timetable as something to confirm with Aer Lingus for your exact dates.

The winter pattern is worth knowing before you plan a trip. In winter 2023-24 the route paused from early January to mid-March, and Aer Lingus's schedule for winter 2025-26 again showed a pause from early January to the start of March. Aer Lingus's announced cuts for winter 2026-27 named other US cities, not Hartford, but that does not guarantee January and February flights. Search your dates before you book anything else.

One-stop options

If the nonstop does not suit your dates, the usual alternatives are:

• Connect through a US hub: fly from Bradley to an airport with its own Dublin flights, such as Boston, New York or Washington Dulles, and continue overnight.
• Drive to Boston or New York: Boston Logan and New York's airports have more Dublin departures, and some Connecticut travellers choose the drive over a connection.
• Connect in Europe: possible, but rarely sensible, because Dublin is the first stop across the Atlantic.

A connection adds hours, so the nonstop is usually the better choice when it runs. Our guide to nonstop vs connecting flights explains the trade-offs.

Flight time and the overnight

Eastbound flights leave Hartford in the evening and reach Dublin early the next morning, Irish time. Six hours in the air is short for an overnight: after the meal service you may get four hours of sleep at best. Eat at the airport, skip the main meal on board, and try to sleep soon after take-off.

The return leaves Dublin in the afternoon and lands in Hartford the same afternoon or early evening. It is a daytime flight, a little longer because of the westerly winds, and easier on the body than the outbound.

Ireland is five hours ahead of Connecticut for most of the year. For a few weeks in March and around late October and early November the gap is four hours, because the US and Ireland change their clocks on different weekends.

Bradley International Airport

Bradley is in Windsor Locks, about 12 miles north of downtown Hartford and roughly half an hour from Springfield, Massachusetts. Passenger flights use Terminal A, so there is no terminal to choose. It is a small airport by transatlantic standards, and security lines are usually short, but check-in and bag drop for an international flight close earlier than for a domestic one. Arrive at least two to three hours before departure; our guide on how early to get to the airport for an international flight covers the details.

Arriving in Dublin

Aer Lingus's transatlantic flights use Terminal 2 at Dublin Airport. You pass Irish immigration on arrival. Dublin Airport is about 10 kilometres north of the city centre. Express coaches and city buses run from outside the terminal to O'Connell Street and other central stops, and the ride usually takes 30 to 45 minutes depending on traffic. Taxis wait outside the terminal, and car hire desks are in the arrivals area if you plan to drive on to the west coast. Remember that Ireland drives on the left.

Entry rules for US citizens

US citizens need a valid passport to enter Ireland and do not need a visa for a tourist visit. Ireland is not part of the Schengen area, so the EU's Entry/Exit System and the future ETIAS authorisation (not yet in operation) do not apply to a trip that stays in Ireland. If you continue to France, Spain or other Schengen countries, those rules start at your first Schengen airport. Northern Ireland is part of the UK: US citizens need a UK Electronic Travel Authorisation (ETA) to visit it or Great Britain from Ireland, even by road with no border check.

Check that your passport is valid for your whole stay, and renew early if it is close to expiry; our guide to passport validity rules explains what airlines check.

Coming home: US preclearance in Dublin

The return has one big advantage. Dublin Airport has US Customs and Border Protection preclearance in Terminal 2, so you clear US immigration and customs in Dublin before you board. Your flight arrives at Bradley as a domestic arrival: you take your bags and leave. Allow extra time in Dublin for preclearance, especially in summer. Our guide to US preclearance explains how it works, including which documents to carry.

Best months to fly

June to August brings the longest days and the most crowded flights, plus summer festivals and family travel. May and September are often the sweet spot: decent weather, long evenings and fewer people at the main sights. Mid-March is busy because of St. Patrick's Day, so book early for that week. Late autumn is quieter and greener, with shorter days and more rain. Whenever you go, pack a waterproof layer: Irish weather changes quickly in every season.

Baggage and fare types

Aer Lingus sells transatlantic economy in several fare types. The cheapest may not include a checked bag or a free seat choice, while higher fares add a bag, seat selection and more flexibility. Compare what is included, not just the headline fare, before you book. Business class on this aircraft has lie-flat seats, which makes a real difference on a short overnight. For a general overview, see our guide to airline baggage rules.

Practical tips for Connecticut travellers

Because there is only one nonstop, the date you need may sell out before the price moves much on Boston or New York flights. If your dates are fixed, look early. If they are flexible, compare BDL with Boston and New York before you decide, and remember to count the drive and parking. Dublin is also a good starting point for the rest of Ireland: Galway, Cork, Kilkenny and the Wicklow Mountains are all reachable by road or rail from the capital.
