What SEA to YYC looks like
The SEA to YYC sector, the carriers on it and the flying time, before anything is promised to anybody.
Seattle SEA to Calgary YYC is a short sector of 726 km by great circle, flown nonstop 6.6 times a day.
At the cruise speed this site models for 726 km, 720 km an hour, and thirty minutes of taxi at the two ends, the flight blocks at about 1h 34m.
Seattle SEA is a large airport in the network held here, 145 scheduled destinations and 717.9 departures a day. Calgary YYC has 105 destinations and 319.5 departures a day.
Calgary runs 2 hours ahead of Seattle in January and one hour ahead 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 SEA to YYC from the scheduled route statistics, both directions, with the operating carriers named.
| Direction | Flights a day | Flights a week | Operated by |
|---|---|---|---|
| SEA to YYC | 6.57 | 46 | Alaska Airlines, WestJet |
| YYC to SEA | 6.71 | 47 | Alaska Airlines, WestJet |
Two carriers hold the sector, Alaska Airlines and WestJet, which gives a missed departure somewhere to go without leaving the nonstop.
At 6.6 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 93 departures a week on SEA to YYC, 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 34m block time on SEA to YYC. 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 YYC in the air, estimated | 94 min | 6h 04m |
| Formalities at YYC | 90 min | 7h 34m |
| Delivery run in Calgary | 45 min | 8h 19m |
| Door to door | 499 min | 8h 19m |
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 YYC is 8h 19m.
A courier who leaves Seattle at 09:00 local is on the ground in Calgary at about 12:34 local and at the door by 14:49 the same day.
Working backwards from a six in the evening handover in Calgary, the last useful departure from Seattle is around 12:11 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. 47 of them join SEA to YYC.
| Connecting at | SEA to hub, flights a day | Hub to YYC, flights a day | Track, km | Estimated, gate to gate |
|---|---|---|---|---|
| Victoria YYJ | 3.57 | 10 | 884 | 3h 18m |
| Edmonton YEG | 2.29 | 11.14 | 1,144 | 3h 31m |
| Vancouver YVR | 19.71 | 41.14 | 891 | 3h 34m |
| Portland PDX | 23 | 1.14 | 1,090 | 3h 41m |
| Salt Lake City SLC | 12.86 | 2.29 | 2,266 | 5h 09m |
| San Francisco SFO | 22.71 | 4.71 | 2,731 | 5h 45m |
With 6.6 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.
47 airports connect the two ends on the scheduled network held here. The quickest of the dependable ones is Victoria YYJ, where the weaker of the two legs still runs 3.6 times a day.
Through YYJ the routing covers 884 km against the 726 km nonstop track and takes about 3h 18m 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 44m more than the nonstop, which is close enough that a connection is worth taking when the nonstop is full or badly timed.
Behind it, Edmonton YEG at 3h 31m and Vancouver YVR at 3h 34m 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 Calgary, Edmonton YEG is 246 km away by great circle and carries 47 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 YYC 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.
