What DUB to SEA looks like
The DUB to SEA sector, the carriers on it and the flying time, before anything is promised to anybody.
Dublin DUB to Seattle SEA is a long haul sector of 7,283 km by great circle, flown nonstop about once a day.
At the cruise speed this site models for 7,283 km, 880 km an hour, and thirty minutes of taxi at the two ends, the flight blocks at about 9h 16m.
Dublin DUB is a major hub in the network held here, 198 scheduled destinations and 462.1 departures a day. Seattle SEA has 145 destinations and 717.9 departures a day.
Seattle is 8 hours behind of Dublin all year.
The pair sits between the Americas and Europe, a corridor where the site already publishes 36 written lanes that go into customs and ground detail this page does not.
Who flies the sector, and how often
Average daily frequencies on DUB to SEA from the scheduled route statistics, both directions, with the operating carriers named.
| Direction | Flights a day | Flights a week | Operated by |
|---|---|---|---|
| DUB to SEA | 1.14 | 8 | Aer Lingus |
| SEA to DUB | 1.14 | 8 | Aer Lingus |
One carrier holds the sector, Aer Lingus, so a cancellation has no second nonstop behind it and the connections below stop being theoretical.
Between them the two directions put about 16 departures a week on DUB to SEA, which is the number that decides whether a seat can be found today or on Thursday.
The clock from collection to signature
The same ground timings the route calculator starts from, applied to the 9h 16m block time on DUB to SEA. Change any of them in the tool further down and the total moves with them.
| Stage | Allowed | Elapsed |
|---|---|---|
| Collection and the run to DUB | 90 min | 1h 30m |
| At DUB before departure | 180 min | 4h 30m |
| DUB to SEA in the air, estimated | 556 min | 13h 46m |
| Formalities at SEA | 90 min | 15h 16m |
| Delivery run in Seattle | 45 min | 16h 01m |
| Door to door | 961 min | 16h 01m |
On the desk standard ground timings, ninety minutes to collect and reach the airport, three hours at the airport before departure, ninety minutes of arrival formalities and a forty five minute delivery run, the door to door figure for DUB to SEA is 16h 01m.
A courier who leaves Dublin at 09:00 local is on the ground in Seattle at about 10:16 local and at the door by 12:31 the same day.
Working backwards from a six in the evening handover in Seattle, the last useful departure from Dublin is around 14:29 local.
At 16h 01m the mission is past the sixteen hour duty day a single courier is planned against, so it is quoted with a rest at the far end or with a second courier, and never as a turnaround.
When the nonstop does not work
Every airport that joins the two ends, ranked by when they land, among the ones whose weaker leg is dependable enough to plan on. Connection time is allowed for the size of the hub. 38 of them join DUB to SEA.
| Connecting at | DUB to hub, flights a day | Hub to SEA, flights a day | Track, km | Estimated, gate to gate |
|---|---|---|---|---|
| Reykjavik KEF | 1.43 | 4.29 | 7,309 | 10h 55m |
| Vancouver YVR | 0.71 | 14.86 | 7,370 | 11h 11m |
| Calgary YYC | 0.57 | 6.71 | 7,316 | 11h 15m |
| Minneapolis MSP | 2.14 | 10.71 | 8,239 | 12h 20m |
| London LHR | 20.57 | 6.71 | 8,151 | 12h 27m |
| Toronto YYZ | 5.29 | 2.29 | 8,568 | 12h 34m |
One nonstop a day means one chance a day, so the connections below are what a consignment that arrives at DUB in the afternoon actually flies on.
38 airports connect the two ends on the scheduled network held here. The quickest of the dependable ones is Reykjavik KEF, where the weaker of the two legs still runs about once a day.
Through KEF the routing covers 7,309 km against the 7,283 km nonstop track and takes about 10h 55m in the air and on the ground at the hub, allowing 60 minutes to connect at an airport of that size.
That is only 1h 39m more than the nonstop, which is close enough that a connection is worth taking when the nonstop is full or badly timed.
Behind it, Vancouver YVR at 11h 11m and Calgary YYC at 11h 15m hold the same connection, so a booking has three hubs to try before it has to wait for the nonstop.
If nothing suitable leaves Dublin, Belfast BFS is 137 km away by great circle and carries 47 scheduled destinations of its own, which is usually a shorter road transfer than a lost day.
If nothing suitable leaves Seattle, Victoria YYJ is 157 km away by great circle and carries 22 scheduled destinations of its own, which is usually a shorter road transfer than a lost day.

Where this came from, and where to look next
- Carriers and frequencies: AeroDataBox scheduled route statistics, retrieved 2026-09-07. Average daily flights, not a timetable.
- Distances: great circle from published coordinates. They read short against a flown track, which is why the block time above applies a factor to them.
- Block and connection times: the same model the route calculator lower down this page runs, at the same rounding.
- Restrictions: the airport notes file, checked 2026-09-07.
- Industrial sites: public company information. Nothing here says or implies that any company named is a customer of any courier operator.
Who publishes this. OnBoard Courier is a placement desk in Dubai. An assignment is carried out by a vetted partner operator, with the desk as the single point of contact from the quote to the signature. This page exists because our own dispatchers need the answer for DUB to SEA in the twenty minutes before a promise is made, and a reference only one operator can read is not a reference. Free to read, quote and cite. Found an error? Tell us and we will correct it.
If you need something moved rather than looked up, the desk prices a hand carry in fifteen minutes.
