The route
The great-circle path — the shortest line between the two airports across the curve of the earth. On a flat map it looks bent; on a globe it is straight.
Flight time at different cruise speeds
Aircraft type, winds and routing all move the real number. This is the same distance flown at different speeds, plus the 25-minute ground and climb allowance.
| Typical of | Cruise speed | Airborne | Gate to gate |
|---|---|---|---|
| Turboprop / regional | 550 km/h | 20h 14m | 20h 39m |
| Narrowbody jet (A320, 737) | 780 km/h | 14h 16m | 14h 41m |
| Widebody jet (777, 787, A350) | 900 km/h | 12h 22m | 12h 47m |
| Private jet (Gulfstream) | 850 km/h | 13h 05m | 13h 31m |
Headwinds on an eastbound long-haul routinely add 30–60 minutes; the same route westbound can be quicker. Airlines publish schedules with padding built in.

Questions
How long is the flight from Hong Kong to San Francisco?
A non-stop flight from Hong Kong (HKG) to San Francisco (SFO) takes about 14h 15m. The great-circle distance is 11,128 km (6,915 miles, 6,009 nautical miles), flying north-east on an initial bearing of 42°.
How far is Hong Kong from San Francisco?
11,128 kilometres in a straight line over the earth's surface — 6,915 miles or 6,009 nautical miles. Actual flown distance is usually 2–5% longer because aircraft follow airways, avoid weather and route around restricted airspace.
Is there a non-stop flight between HKG and SFO?
This page calculates the direct-line time and distance; it does not track airline schedules. At 11,128 km the route is within reach of long-range widebodies, though not every city pair is served non-stop. Check an airline or booking site for what is actually scheduled.
What should I expect on a 14h 15m flight?
Anything past six hours is a long-haul flight: expect at least one meal service, a significant time-zone shift, and enough sitting that circulation and hydration start to matter. Cabin altitude, dry air and disrupted sleep do more damage to a training routine than the flight itself.
