JFK to DUB: distance bands, operating airlines, connection choices and disruption evidence for this direction of travel.
Examples, not a daily timetable. Confirm the operating airline, airports and stops on your booking.
The great-circle distance between JFK and DUB is approximately 5,103 km, in the over 3,500 km band. This endpoint calculation does not add detours. For a through connection, check the original departure and last ticketed destination before selecting a compensation band.
Dublin has US preclearance, but do not assume every JFK departure completes it: Aer Lingus identifies exceptions for evening departures. Verify your flight's instructions. Queueing at immigration and an airline-caused missed connection are different facts; note when you reached each checkpoint and gate.
For a standalone JFK–DUB arrival from outside Europe, EU261 generally requires an eligible EU/EEA or Swiss operating carrier. A European ticket seller is insufficient. Keep any compensation or assistance already received under another country's rules in the evidence record.
If you came from a UK airport via Dublin on a single ticket, use the full itinerary when checking protection and final delay. DUB–JFK alone is only the Atlantic sector. For a separate Dublin departure ticket, proof of timely presentation at the gate remains important even when preclearance is busy.
Dublin's US preclearance makes some transatlantic connections different from an ordinary departure. Confirm whether your specific US flight uses the facility; the airport says most direct US departures from Terminal 2 do, but not every flight.
