What SEA to BOI looks like
The SEA to BOI sector, the carriers on it and the flying time, before anything is promised to anybody.
Seattle SEA to Boise BOI is a short sector of 641 km by great circle, flown nonstop 15.9 times a day.
At the cruise speed this site models for 641 km, 720 km an hour, and thirty minutes of taxi at the two ends, the flight blocks at about 1h 27m.
Seattle SEA is a large airport in the network held here, 145 scheduled destinations and 717.9 departures a day. Boise BOI has 67 destinations and 105.9 departures a day.
Seattle carries about 6.8 times the departures of Boise, so a courier who has to be rebooked has far more to work with at one end of this pair than at the other.
Boise is one hour ahead of Seattle all year.
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 BOI from the scheduled route statistics, both directions, with the operating carriers named.
| Direction | Flights a day | Flights a week | Operated by |
|---|---|---|---|
| SEA to BOI | 15.86 | 111 | Alaska Airlines, Delta Air Lines, NetJets Aviation |
| BOI to SEA | 15.57 | 109 | Alaska Airlines, Delta Air Lines |
3 carriers are recorded on the sector, so a missed departure is normally a rebooking rather than a lost day.
At 15.9 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 220 departures a week on SEA to BOI, 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 1h 27m block time on SEA to BOI. 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 BOI in the air, estimated | 87 min | 5h 57m |
| Formalities at BOI | 90 min | 7h 27m |
| Delivery run in Boise | 45 min | 8h 12m |
| Door to door | 492 min | 8h 12m |
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 BOI is 8h 12m.
A courier who leaves Seattle at 09:00 local is on the ground in Boise at about 11:27 local and at the door by 13:42 the same day.
Working backwards from a six in the evening handover in Boise, the last useful departure from Seattle is around 13:18 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. 18 of them join SEA to BOI.
| Connecting at | SEA to hub, flights a day | Hub to BOI, flights a day | Track, km | Estimated, gate to gate |
|---|---|---|---|---|
| Portland PDX | 23 | 5.43 | 761 | 3h 22m |
| Salt Lake City SLC | 12.86 | 6.71 | 1,573 | 4h 21m |
| Oakland OAK | 8.57 | 1.29 | 1,905 | 4h 26m |
| San Francisco SFO | 22.71 | 5.43 | 1,933 | 4h 43m |
| San Jose SJC | 15.71 | 2.43 | 1,963 | 4h 45m |
| Las Vegas LAS | 17.43 | 4.29 | 2,232 | 5h 21m |
With 15.9 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.
18 airports connect the two ends on the scheduled network held here. The quickest of the dependable ones is Portland PDX, where the weaker of the two legs still runs 5.4 times a day.
Through PDX the routing covers 761 km against the 641 km nonstop track and takes about 3h 22m 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 55m more than the nonstop, which is close enough that a connection is worth taking when the nonstop is full or badly timed.
Behind it, Salt Lake City SLC at 4h 21m and Oakland OAK at 4h 26m 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 SEA to BOI 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.
