Hong Kong to San Diego
15h 08mgate to gate
The flight from Hong Kong International Airport (HKG) to San Diego International Airport (SAN) covers 11,838 km (7,356 miles) and takes approximately 15h 08m gate to gate for a typical jet.
The route heads north-east on an initial great-circle bearing of 43°, passing near 50.2° N, 172.7° E at its midpoint.

How this is worked out
- Take both airports' published coordinates from OurAirports — nothing here is scraped from another flight site.
- Great-circle distance by haversine on a mean earth radius of 6,371.0088 km: 11,838 km.
- Airborne time = that distance ÷ 805 km/h, a representative jet cruise speed: 14h 42m.
- Add a flat 25 minutes for pushback, taxi, climb, descent and taxi-in — the reason a 400 km hop is never half an hour: 15h 08m gate to gate.
- Winds, aircraft type and airline schedule padding are not modelled. The cruise-speed table shows how much that assumption is worth.
11,838 km / 805 km/h = 14h 42m airborne
+ 25 min ground = 15h 08m gate to gate

The same route, plotted on a world grid
The strip above gives the route its length and its shape. This gives it a position: latitude and longitude only, no coastlines, because a hand-drawn coastline would be decoration pretending to be data. On a flat grid the shortest path 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 | 21h 31m | 21h 57m |
| Narrowbody jet (A320, 737) | 780 km/h | 15h 11m | 15h 36m |
| Widebody jet (777, 787, A350) | 900 km/h | 13h 09m | 13h 34m |
| Private jet (Gulfstream) | 850 km/h | 13h 56m | 14h 21m |
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 this plate answers
How long is the flight from Hong Kong to San Diego?
A non-stop flight from Hong Kong (HKG) to San Diego (SAN) takes about 15h 08m. The great-circle distance is 11,838 km (7,356 miles, 6,392 nautical miles), flying north-east on an initial bearing of 43°.
How far is Hong Kong from San Diego?
11,838 kilometres in a straight line over the earth's surface — 7,356 miles or 6,392 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 SAN?
This page calculates the direct-line time and distance; it does not track airline schedules. At 11,838 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 15h 08m 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.
