What ZRH to SFO looks like
The ZRH to SFO sector, the carriers on it and the flying time, before anything is promised to anybody.
Zurich ZRH to San Francisco SFO is an ultra long sector of 9,376 km by great circle, flown nonstop 3.3 times a day.
At the cruise speed this site models for 9,376 km, 880 km an hour, and thirty minutes of taxi at the two ends, the flight blocks at about 11h 48m.
Zurich ZRH is a major hub in the network held here, 223 scheduled destinations and 457.1 departures a day. San Francisco SFO has 189 destinations and 656.9 departures a day.
San Francisco is 9 hours behind of Zurich all year.
The pair sits between the Americas and Europe, a corridor where the site already publishes 36 written lanes that go into customs and ground detail this page does not.
Who flies the sector, and how often
Average daily frequencies on ZRH to SFO from the scheduled route statistics, both directions, with the operating carriers named.
| Direction | Flights a day | Flights a week | Operated by |
|---|---|---|---|
| ZRH to SFO | 3.29 | 23 | SWISS, United Airlines |
| SFO to ZRH | 2.29 | 16 | SWISS, United Airlines |
Two carriers hold the sector, SWISS and United Airlines, which gives a missed departure somewhere to go without leaving the nonstop.
The two directions are not level: ZRH to SFO runs 3.3 times a day, the return runs about twice a day, and a round trip has to be planned around the thinner of the two.
At 3.3 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 39.1 departures a week on ZRH to SFO, 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 11h 48m block time on ZRH to SFO. Change any of them in the tool further down and the total moves with them.
| Stage | Allowed | Elapsed |
|---|---|---|
| Collection and the run to ZRH | 90 min | 1h 30m |
| At ZRH before departure | 180 min | 4h 30m |
| ZRH to SFO in the air, estimated | 708 min | 16h 18m |
| Formalities at SFO | 90 min | 17h 48m |
| Delivery run in San Francisco | 45 min | 18h 33m |
| Door to door | 1,113 min | 18h 33m |
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 ZRH to SFO is 18h 33m.
A courier who leaves Zurich at 09:00 local is on the ground in San Francisco at about 11:48 local and at the door by 14:03 the same day.
Working backwards from a six in the evening handover in San Francisco, the last useful departure from Zurich is around 12:57 local.
At 18h 33m 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. 38 of them join ZRH to SFO.
| Connecting at | ZRH to hub, flights a day | Hub to SFO, flights a day | Track, km | Estimated, gate to gate |
|---|---|---|---|---|
| Dublin DUB | 4.29 | 1.14 | 9,420 | 13h 41m |
| Vancouver YVR | 0.86 | 10.43 | 9,597 | 13h 54m |
| Frankfurt FRA | 14.43 | 4.71 | 9,433 | 13h 56m |
| Amsterdam AMS | 11.43 | 2.29 | 9,388 | 13h 58m |
| Paris CDG | 9 | 3.29 | 9,438 | 14h 00m |
| London LHR | 12 | 7.43 | 9,404 | 14h 03m |
With 3.3 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.
38 airports connect the two ends on the scheduled network held here. The quickest of the dependable ones is Dublin DUB, where the weaker of the two legs still runs about once a day.
Through DUB the routing covers 9,420 km against the 9,376 km nonstop track and takes about 13h 41m 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 53m more than the nonstop, which is close enough that a connection is worth taking when the nonstop is full or badly timed.
Behind it, Vancouver YVR at 13h 54m and Frankfurt FRA at 13h 56m hold the same connection, so a booking has three hubs to try before it has to wait for the nonstop.
If nothing suitable leaves Zurich, Basel BSL is 78 km away by great circle and carries 122 scheduled destinations of its own, which is usually a shorter road transfer than a lost day.
If nothing suitable leaves San Francisco, Oakland OAK is 18 km away by great circle and carries 89 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.
Zurich ZRH is shut to scheduled movements between 23:00 and 06:00 local, so a collection in Zurich that runs late does not simply catch a later flight, it waits for the morning and loses a working day in San Francisco.
Zurich ZRH, night restrictions: Scheduled movements end at 23:00 local, with delayed flights permitted until 23:30. Nothing scheduled before 06:00.

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 ZRH to SFO 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.
