Which rules cover SEA–DUB
Seattle → Dublin
Whatever the airline, this direction is covered by US DOT (the flight departs from the United States (14 CFR 260.2, "covered flight")). On an EU airline it is also under EU261. On a UK airline it is also under UK261. If the airline refuses, the complaint goes to the US DOT for the refund, Irish Aviation Authority for EU261 (the flight arrives in Ireland from outside the EU) or the airline's dispute scheme or the UK CAA for UK261.
Dublin → Seattle
Whatever the airline, this direction is covered by EU261 (the flight departs from the EU (Article 3(1)(a)), whatever the airline) and US DOT (the flight arrives in the United States (14 CFR 260.2, "covered flight")). If the airline refuses, the complaint goes to Irish Aviation Authority for EU261 (the flight leaves Ireland) or the US DOT for the refund.
Because both EU and UK rules can reach this route, a passenger may find two rules covering the same trip. Each excludes people already compensated under the other's law for the same event, so the claim is made once, under whichever the airline accepts — in money terms €600 or £520.
What you could be owed by hours late
Arrival delay at DUB (or SEA on the return), for a delay caused by the airline, per passenger, where each rule applies:
| Hours late | EU261 | UK261 | US DOT |
|---|---|---|---|
| 2 hours | €0 | £0 | Nothing |
| 3 h 30 min | €300 | £260 | Nothing |
| 4 h 30 min | €600 | £520 | Nothing |
| 6 h 30 min | €600 | £520 | Refund if you decline |
| 9 h 30 min | €600 | £520 | Refund if you decline |
At 7,283 km this is a long-haul flight, so the first hour of compensation is reduced: arriving 3 to 4 hours late pays €300 or £260, and the full €600/£520 starts at 4 hours. The US column is the refund right only: an international itinerary needs 6+ hours.
How Seattle SEA runs
In June 2026, 76.9% of reporting airlines' flights arriving at Seattle–Tacoma International Airport and 74% of those departing were on time (within 15 minutes), against 72.9% and 70.7% across the 30 largest US airports, according to the US DOT's Air Travel Consumer Report. Arrivals here ran at or above that average. The figures cover all reported flights at the airport, mostly domestic, not this route alone.
The distance and the band
EU261 and UK261 measure distance "by the great circle route method" between the departure airport and the final destination. From the published coordinates of Seattle–Tacoma International Airport (47.447943, -122.310276) and Dublin Airport (53.428713, -6.262121) that is 7,283 km. The nearest band boundary is 3,500 km, 3,783 km below this route, so the band is not in doubt. Among the 148 routes on this site in the over 3,500 km band, it is number 42 by length.
Other routes from Seattle–Tacoma International Airport (KSEA) on this site: London (7,702 km), Paris (8,049 km), Amsterdam (7,840 km), Vancouver (205 km).
Other routes from Dublin Airport (EIDW) on this site: London (449 km), Faro (1,830 km), Boston (4,803 km), New York (5,103 km), Chicago (5,895 km), Newark (5,125 km), Philadelphia (5,253 km), Washington (5,464 km), Atlanta (6,323 km), Los Angeles (8,318 km), Toronto (5,261 km), London (470 km), Birmingham (321 km), Manchester (264 km), Edinburgh (336 km).
If SEA–DUB is only one leg of your booking, measure to the final destination instead: a connection that makes you late at the end is compensated over the whole journey's distance.
If the flight is cancelled
Cancelled with less than 14 days' notice and re-routed to arrive 6 hours late, an EU261 passenger is owed €600 here. If the replacement left within the allowed early margin and landed within the re-routing window, nothing is owed; if it landed within 4 hours but outside those windows, the airline may pay half — €300. On a cancellation you may instead take a refund within 7 days.
Help at the airport while you wait
On a flight of this length, meals and refreshments are owed once the departure is 4 hours late under EU261 and UK261, and a hotel with transport if you have to stay overnight — whatever caused the delay. US law sets no meal or hotel duty; the large US airlines' published commitments do, and they are on the airline pages. Keep receipts for anything you buy: it is claimed back separately from any compensation.
Claiming on this route
Claim from the operating airline directly — it costs nothing.
US DOT: If it refuses, file a complaint with the US Department of Transportation's Aviation Consumer Protection office.
EU261: If the airline does not reply within two months, or the reply is unsatisfactory, complain to the national enforcement body of the country where the incident happened.
UK261: If the airline's final answer is unsatisfactory, or it has not answered within eight weeks, go to the alternative dispute resolution (ADR) body the airline belongs to, or to the CAA's Passenger Advice and Complaints Team if it belongs to none.
