What PHX to SEA looks like
The PHX to SEA sector, the carriers on it and the flying time, before anything is promised to anybody.
Phoenix PHX to Seattle SEA is a medium haul sector of 1,782 km by great circle, flown nonstop 20.9 times a day.
At the cruise speed this site models for 1,782 km, 830 km an hour, and thirty minutes of taxi at the two ends, the flight blocks at about 2h 47m.
Phoenix PHX is a major hub in the network held here, 172 scheduled destinations and 603.4 departures a day. Seattle SEA has 145 destinations and 717.9 departures a day.
Seattle runs one hour behind of Phoenix in January and no time shift at all in July, because the two ends do not change their clocks together.
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 PHX to SEA from the scheduled route statistics, both directions, with the operating carriers named.
| Direction | Flights a day | Flights a week | Operated by |
|---|---|---|---|
| PHX to SEA | 20.86 | 146 | Alaska Airlines, American Airlines, Delta Air Lines, Envoy Air, Southwest Airlines |
| SEA to PHX | 20.43 | 143 | Alaska Airlines, American Airlines, Delta Air Lines, Envoy Air, Southwest Airlines |
5 carriers are recorded on the sector, so a missed departure is normally a rebooking rather than a lost day.
At 20.9 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 289 departures a week on PHX 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 2h 47m block time on PHX 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 PHX | 90 min | 1h 30m |
| At PHX before departure | 180 min | 4h 30m |
| PHX to SEA in the air, estimated | 167 min | 7h 17m |
| Formalities at SEA | 90 min | 8h 47m |
| Delivery run in Seattle | 45 min | 9h 32m |
| Door to door | 572 min | 9h 32m |
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 PHX to SEA is 9h 32m.
A courier who leaves Phoenix at 09:00 local is on the ground in Seattle at about 10:47 local and at the door by 13:02 the same day.
Working backwards from a six in the evening handover in Seattle, the last useful departure from Phoenix is around 13:58 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. 59 of them join PHX to SEA.
| Connecting at | PHX to hub, flights a day | Hub to SEA, flights a day | Track, km | Estimated, gate to gate |
|---|---|---|---|---|
| Boise BOI | 6.86 | 15.57 | 1,825 | 4h 28m |
| Portland PDX | 10.86 | 22.43 | 1,833 | 4h 38m |
| Salt Lake City SLC | 15.86 | 12.71 | 1,925 | 4h 43m |
| Oakland OAK | 5.29 | 8.43 | 2,120 | 4h 43m |
| Las Vegas LAS | 18.14 | 17.29 | 1,806 | 4h 53m |
| San Jose SJC | 7.86 | 15.71 | 2,121 | 4h 58m |
With 20.9 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.
59 airports connect the two ends on the scheduled network held here. The quickest of the dependable ones is Boise BOI, where the weaker of the two legs still runs 6.9 times a day.
Through BOI the routing covers 1,825 km against the 1,782 km nonstop track and takes about 4h 28m 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 41m 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 38m and Salt Lake City SLC at 4h 43m 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.

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 PHX 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.
