What SEA to LAX looks like
The SEA to LAX sector, the carriers on it and the flying time, before anything is promised to anybody.
Seattle SEA to Los Angeles LAX is a medium haul sector of 1,537 km by great circle, flown nonstop 26.3 times a day.
At the cruise speed this site models for 1,537 km, 830 km an hour, and thirty minutes of taxi at the two ends, the flight blocks at about 2h 28m.
Seattle SEA is a large airport in the network held here, 145 scheduled destinations and 717.9 departures a day. Los Angeles LAX has 212 destinations and 826.3 departures a day.
Seattle and Los Angeles keep the same clock all year, so the arrival time is the departure time plus the block and nothing else.
The pair sits inside the Americas, a corridor where the site already publishes 13 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 LAX from the scheduled route statistics, both directions, with the operating carriers named.
| Direction | Flights a day | Flights a week | Operated by |
|---|---|---|---|
| SEA to LAX | 26.29 | 184 | Alaska Airlines, American Airlines, Delta Air Lines, Frontier Airlines, United Airlines |
| LAX to SEA | 26.29 | 184 | Alaska Airlines, American Airlines, Delta Air Lines, Frontier Airlines, United Airlines |
5 carriers are recorded on the sector, so a missed departure is normally a rebooking rather than a lost day.
At 26.3 times a day there is usually another departure within a few hours, which is what makes a same day booking on this pair realistic.
Between them the two directions put about 368.1 departures a week on SEA to LAX, 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 2h 28m block time on SEA to LAX. 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 LAX in the air, estimated | 148 min | 6h 58m |
| Formalities at LAX | 90 min | 8h 28m |
| Delivery run in Los Angeles | 45 min | 9h 13m |
| Door to door | 553 min | 9h 13m |
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 LAX is 9h 13m.
A courier who leaves Seattle at 09:00 local is on the ground in Los Angeles at about 11:28 local and at the door by 13:43 the same day.
Working backwards from a six in the evening handover in Los Angeles, the last useful departure from Seattle is around 13:17 local.
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. 78 of them join SEA to LAX.
| Connecting at | SEA to hub, flights a day | Hub to LAX, flights a day | Track, km | Estimated, gate to gate |
|---|---|---|---|---|
| Oakland OAK | 8.57 | 6.57 | 1,625 | 4h 11m |
| Portland PDX | 23 | 13.43 | 1,551 | 4h 16m |
| Boise BOI | 15.86 | 4.64 | 1,727 | 4h 20m |
| San Jose SJC | 15.71 | 14.86 | 1,618 | 4h 25m |
| San Francisco SFO | 22.71 | 42.71 | 1,636 | 4h 27m |
| San Diego SAN | 17 | 8.23 | 1,868 | 4h 41m |
With 26.3 times a day on the nonstop, a connection here is a disruption plan rather than a routing, and it is listed because a closed runway or a cancellation wave is exactly when nobody has time to work it out.
78 airports connect the two ends on the scheduled network held here. The quickest of the dependable ones is Oakland OAK, where the weaker of the two legs still runs 6.6 times a day.
Through OAK the routing covers 1,625 km against the 1,537 km nonstop track and takes about 4h 11m 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 43m more than the nonstop, which is close enough that a connection is worth taking when the nonstop is full or badly timed.
Behind it, Portland PDX at 4h 16m and Boise BOI at 4h 20m 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 Los Angeles, San Diego SAN is 176 km away by great circle and carries 123 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 SEA to LAX 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.
