No public record scores Dublin to Bradley International flight by flight. The US Department of Transportation's on-time database covers domestic flights only, and in Europe only the United Kingdom publishes punctuality by route, so what follows is built from the three measurements that do exist. The DOT's international report counts 542 flights between the two airports in the twelve months to June 2026, about five departures a week in each direction, flown by Aer Lingus. EUROCONTROL's year-to-date figure has 75.7% of all departures from Dublin leaving within 15 minutes of schedule and 73.7% of arrivals landing within 15 minutes. At the other end, 78.4% of BDL's domestic departures arrived on time in the DOT data, which says something about how the airport itself runs, not about this route.
On EUROCONTROL's year-to-date arrival punctuality, Dublin ranks 34th of the 41 European airports on this site with service to the United States. Bilbao leads that table at 84.3% and Manchester closes it at 65.7%. A long-haul departure inherits the airport's morning: an aircraft that arrived late from its previous sector, or a departure queue built up by weather, delays the transatlantic wave with everything else.

Without a route-level record, the useful question is what the two airports do to a schedule. EUROCONTROL attributes 0.3 minutes of air traffic flow management delay per arriving flight to Dublin so far this year; that is delay imposed by the network to hold traffic on the ground elsewhere, not the airline's own. The DOT data has no delay figure for BDL.
Carrier by carrier
Who flies DUB to BDL
Aer Lingus is the only carrier the DOT report shows on DUB to BDL, with 542 flights and an average of 130 passengers aboard each. A single-carrier route gives a delayed passenger no same-day alternative on the same ticket, which is worth knowing before booking a tight onward connection.

Across the year
How often DUB to BDL flies through the year
The DOT's international report puts 62 flights on the pair in July 2025, the busiest month of the window, and 0 in February 2026, the thinnest. A summer-to-winter swing of that size means the winter schedule is a different operation: fewer frequencies, so a cancellation leaves a longer wait for the next seat.

The arrival airport
Landing at Bradley International
Bradley International is scored on this site from the DOT's domestic data: 78.4% of its 22,115 domestic departures arrived on time over the last twelve months, and 2.45% were cancelled. Those are domestic flights, not this route, but an arriving transatlantic flight shares the same runways, the same weather and the same ground delay programmes, so a bad day at BDL reaches a flight from DUB just as surely. The airport flies too little domestic traffic for a page of its own here.

Your rights
EC 261/2004 on DUB to BDL
Every flight that departs Dublin falls under Regulation (EC) 261/2004, whichever airline flies it and wherever it lands. If it arrives at Bradley International three hours or more late, or is cancelled with under 14 days' notice, and the cause was within the airline's control, each passenger is owed €600 (€300 if the airline got you there under four hours late), on top of rebooking and care. Weather, air traffic control restrictions and strikes outside the airline are the usual exemptions. The return flight from BDL is covered only when the carrier is EU based. The sector is about 3,070 miles, 4,940 km, which puts it in the top distance band.

What to do with this
Booking DUB to BDL
There is no grade to give DUB to BDL without a route record, and this site does not invent one. What the three sources support: about five departures a week in each direction, a single carrier, a departure airport that gets 76% of its departures away on time and an arrival airport that runs 78% on time domestically. Leave two hours for any onward connection at BDL; immigration comes before the connecting flight.
Common questions
DUB to BDL questions
How often are DUB to BDL flights delayed?
No public dataset records delays for this route flight by flight: the US on-time database is domestic only and only the UK publishes route-level punctuality in Europe.

Which airlines fly DUB to BDL?
Aer Lingus. Aer Lingus accounted for 100% of the 542 flights the DOT counted on the pair.
Can I claim compensation for a delayed DUB to BDL flight?
Yes, if the flight arrived three hours or more late or was cancelled at short notice for a reason within the airline's control: departures from Dublin are covered by EC 261/2004 whichever airline operates them. The fixed amount for a sector of this length is €600 a passenger, €300 if the airline got you there under four hours late. The return from BDL is covered only on an EU carrier.
