What SFO to HKG looks like
The SFO to HKG sector, the carriers on it and the flying time, before anything is promised to anybody.
San Francisco SFO to Hong Kong HKG is an ultra long sector of 11,128 km by great circle, flown nonstop 4.6 times a day.
At the cruise speed this site models for 11,128 km, 880 km an hour, and thirty minutes of taxi at the two ends, the flight blocks at about 13h 54m.
San Francisco SFO is a major hub in the network held here, 189 scheduled destinations and 656.9 departures a day. Hong Kong HKG has 144 destinations and 478.9 departures a day.
Hong Kong runs 16 hours ahead of San Francisco in January and 15 hours ahead in July, because the two ends do not change their clocks together.
The pair sits between the Americas and Asia Pacific, a corridor where the site already publishes 16 written lanes that go into customs and ground detail this page does not.
Who flies the sector, and how often
Average daily frequencies on SFO to HKG from the scheduled route statistics, both directions, with the operating carriers named.
| Direction | Flights a day | Flights a week | Operated by |
|---|---|---|---|
| SFO to HKG | 4.57 | 32 | Cathay Pacific, United Airlines |
| HKG to SFO | 4.57 | 32 | Cathay Pacific, United Airlines |
Two carriers hold the sector, Cathay Pacific and United Airlines, which gives a missed departure somewhere to go without leaving the nonstop.
At 4.6 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 64 departures a week on SFO to HKG, 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 13h 54m block time on SFO to HKG. Change any of them in the tool further down and the total moves with them.
| Stage | Allowed | Elapsed |
|---|---|---|
| Collection and the run to SFO | 90 min | 1h 30m |
| At SFO before departure | 180 min | 4h 30m |
| SFO to HKG in the air, estimated | 834 min | 18h 24m |
| Formalities at HKG | 90 min | 19h 54m |
| Delivery run in Hong Kong | 45 min | 20h 39m |
| Door to door | 1,239 min | 20h 39m |
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 SFO to HKG is 20h 39m.
A courier who leaves San Francisco at 09:00 local is on the ground in Hong Kong at about 14:54 local and at the door by 17:09 the following day.
Working backwards from a six in the evening handover in Hong Kong, nothing leaving San Francisco inside a normal working day arrives in time, so this pair is an overnight and a next morning delivery rather than a same day one.
At 20h 39m 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. 40 of them join SFO to HKG.
| Connecting at | SFO to hub, flights a day | Hub to HKG, flights a day | Track, km | Estimated, gate to gate |
|---|---|---|---|---|
| Osaka KIX | 1 | 21.57 | 11,168 | 15h 38m |
| Anchorage ANC | 2.29 | 4 | 11,409 | 15h 44m |
| Taipei TPE | 8.71 | 41.86 | 11,197 | 15h 48m |
| Seoul ICN | 7.71 | 23.86 | 11,155 | 15h 51m |
| Tokyo HND | 3.43 | 9 | 11,189 | 15h 56m |
| Tokyo NRT | 1.14 | 24.29 | 11,190 | 15h 57m |
With 4.6 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.
40 airports connect the two ends on the scheduled network held here. The quickest of the dependable ones is Osaka KIX, where the weaker of the two legs still runs about once a day.
Through KIX the routing covers 11,168 km against the 11,128 km nonstop track and takes about 15h 38m 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, Anchorage ANC at 15h 44m and Taipei TPE at 15h 48m hold the same connection, so a booking has three hubs to try before it has to wait for the nonstop.
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.
If nothing suitable leaves Hong Kong, Macau MFM is 38 km away by great circle and carries 39 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 SFO to HKG 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.
