DUB→JFK

Aer Lingus flew 61% of the 2,795 flights between DUB and JFK in the DOT's count, with Delta Air Lines on 721 and JetBlue Airways on 358. Loads averaged 215 passengers a flight, which on this route means wide-body aircraft nearly full.

The DOT's international report puts 303 flights on the pair in May 2026, the busiest month of the window, and 158 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.

EUROCONTROL's figures for Dublin as a whole, every airline and every destination: 75.7% of departures and 73.7% of arrivals within 15 minutes of schedule from 1 January to 21 October 2026, with 97.5% of scheduled flights operated. The last seven days ran at 77.0% for departures, about a point better than the year so far. Air traffic flow management delay attributed to the airport averaged 0.3 minutes per arriving flight this year, 0.0 over the last week.

Every US route from Dublin, and its full punctuality record

John F. Kennedy International is scored on this site from the DOT's domestic data: 74.3% of its 102,713 domestic departures arrived on time over the last twelve months, with delayed flights running a little over an hour late, and 3.98% 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 JFK reaches a flight from DUB just as surely. The airport's own page has the hour-by-hour and month-by-month detail, and its live FAA status appears above when the FAA has something to say.

John F. Kennedy International (JFK) delay statistics, hour by hour and month by month

Every flight that departs Dublin falls under Regulation (EC) 261/2004, whichever airline flies it and wherever it lands. If it arrives at John F. Kennedy 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 JFK is covered only when the carrier is EU based. The sector is about 3,171 miles, 5,102 km, which puts it in the top distance band.

There is no grade to give DUB to JFK without a route record, and this site does not invent one. What the three sources support: about four departures a day in each direction, a choice of three carriers, a departure airport that gets 76% of its departures away on time and an arrival airport that runs 74% on time domestically. Leave two hours for any onward connection at JFK; immigration comes before the connecting flight.

Ireland publishes no route-level punctuality, so this page cannot grade the route. The UK pages in this section can, because the CAA does.
