What SEA to NRT looks like
The SEA to NRT sector, the carriers on it and the flying time, before anything is promised to anybody.
Seattle SEA to Tokyo NRT is an ultra long sector of 7,656 km by great circle, flown nonstop about twice a day.
At the cruise speed this site models for 7,656 km, 880 km an hour, and thirty minutes of taxi at the two ends, the flight blocks at about 9h 43m.
Seattle SEA is a large airport in the network held here, 145 scheduled destinations and 717.9 departures a day. Tokyo NRT has 117 destinations and 361.5 departures a day.
Tokyo runs 17 hours ahead of Seattle in January and 16 hours ahead in July, because the two ends do not change their clocks together.
The pair sits between the Americas and Asia Pacific, a corridor where the site already publishes 16 written lanes that go into customs and ground detail this page does not.
Who flies the sector, and how often
Average daily frequencies on SEA to NRT from the scheduled route statistics, both directions, with the operating carriers named.
| Direction | Flights a day | Flights a week | Operated by |
|---|---|---|---|
| SEA to NRT | 2.29 | 16 | Alaska Airlines |
| NRT to SEA | 2.14 | 15 | Alaska Airlines, Jet Linx Aviation |
Two carriers hold the sector, Alaska Airlines and Jet Linx Aviation, which gives a missed departure somewhere to go without leaving the nonstop.
Between them the two directions put about 31 departures a week on SEA to NRT, 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 43m block time on SEA to NRT. Change any of them in the tool further down and the total moves with them.
| Stage | Allowed | Elapsed |
|---|---|---|
| Collection and the run to SEA | 90 min | 1h 30m |
| At SEA before departure | 180 min | 4h 30m |
| SEA to NRT in the air, estimated | 583 min | 14h 13m |
| Formalities at NRT | 90 min | 15h 43m |
| Delivery run in Tokyo | 45 min | 16h 28m |
| Door to door | 988 min | 16h 28m |
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 SEA to NRT is 16h 28m.
A courier who leaves Seattle at 09:00 local is on the ground in Tokyo at about 11:43 local and at the door by 13:58 the following day.
Working backwards from a six in the evening handover in Tokyo, nothing leaving Seattle inside a normal working day arrives in time, so this pair is an overnight and a next morning delivery rather than a same day one.
At 16h 28m 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. 27 of them join SEA to NRT.
| Connecting at | SEA to hub, flights a day | Hub to NRT, flights a day | Track, km | Estimated, gate to gate |
|---|---|---|---|---|
| Vancouver YVR | 19.71 | 3.29 | 7,708 | 11h 35m |
| Anchorage ANC | 25.57 | 0.57 | 7,840 | 11h 37m |
| Calgary YYC | 6.57 | 1.14 | 8,672 | 12h 53m |
| San Francisco SFO | 22.71 | 1.14 | 9,321 | 13h 34m |
| Seoul ICN | 4.86 | 49.29 | 9,630 | 13h 56m |
| Honolulu HNL | 8.57 | 2.29 | 10,444 | 14h 34m |
One nonstop a day means one chance a day, so the connections below are what a consignment that arrives at SEA in the afternoon actually flies on.
27 airports connect the two ends on the scheduled network held here. The quickest of the dependable ones is Vancouver YVR, where the weaker of the two legs still runs 3.3 times a day.
Through YVR the routing covers 7,708 km against the 7,656 km nonstop track and takes about 11h 35m in the air and on the ground at the hub, allowing 75 minutes to connect at an airport of that size.
That is only 1h 52m more than the nonstop, which is close enough that a connection is worth taking when the nonstop is full or badly timed.
Behind it, Anchorage ANC at 11h 37m and Calgary YYC at 12h 53m hold the same connection, so a booking has three hubs to try before it has to wait for the nonstop.
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.
If nothing suitable leaves Tokyo, Tokyo HND is 60 km away by great circle and carries 105 scheduled destinations of its own, which is usually a shorter road transfer than a lost day.
Restricted hours at either end
Widely documented operating restrictions, checked 2026-09-07. Exemptions and seasonal variations exist, so confirm with the carrier before relying on any of them.
Tokyo NRT is shut to scheduled movements between 23:00 and 06:00 local, which matters here because an aircraft leaving Seattle late arrives into a closed airport rather than a quiet one.
Tokyo NRT, night restrictions: Scheduled movements are limited between 23:00 and 06:00 local; late departures usually route through Haneda instead.
Read back down the sector, a departure from Seattle later than about 20:17 local arrives at NRT after it has closed for the night, on the 9h 43m block time above.

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 SEA to NRT 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.
