How long is the flight to Ireland from each US airport?
The FAA’s busiest US airports by passengers in 2024, the quickest first. Times are the estimated gate-to-gate time of a non-stop; the clock change is Ireland’s time minus the airport’s, in January and in July.

2 of these routes are longer than any US route the estimate was measured on (4,983 miles), so treat those as a rough guide: the longer the flight, the more the wind moves it. LaGuardia, the 19th busiest, is left out: its flights are short-haul, and New York’s long flights leave from JFK and Newark.
Why the flight home is longer
From New York JFK the flight to Dublin is about 6 h 41 min and the flight back 7 h 16 min. The difference is the jet stream, the band of west-to-east wind at cruising height: flying east you ride it, flying west you fly into it. The estimate carries that as a single measured effect of how far east a route goes, which is why the two directions of the same route differ.
What the clock says when you land
Ireland is 5 hours ahead of New York and 8 hours ahead of Los Angeles all year. Leave New York JFK at noon on Wednesday, July 15, and a non-stop would land in Dublin at about 11:41 p.m. the same day, local time.

How these times are made
Distances are great circles between the airports (OurAirports). Times come from one line fitted to the median scheduled gate-to-gate time of 5,797 US routes (US DOT, 2026-06): a fixed allowance, a time per mile, and a correction for how far east the route goes. Half of those routes are within 7 minutes of it. The busiest airports are the FAA’s 2024 passenger boardings. Your airline’s schedule is the real answer: winds, routings and the season move it by a few minutes on a short flight and by more on a long one.
