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 | 18h 59m | 19h 24m |
| Narrowbody jet (A320, 737) | 780 km/h | 13h 23m | 13h 48m |
| Widebody jet (777, 787, A350) | 900 km/h | 11h 36m | 12h 01m |
| Private jet (Gulfstream) | 850 km/h | 12h 17m | 12h 42m |
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 Seattle to Hong Kong?
A non-stop flight from Seattle (SEA) to Hong Kong (HKG) takes about 13h 23m. The great-circle distance is 10,442 km (6,488 miles, 5,638 nautical miles), flying north-west on an initial bearing of 310°.
How far is Seattle from Hong Kong?
10,442 kilometres in a straight line over the earth's surface — 6,488 miles or 5,638 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 SEA and HKG?
This page calculates the direct-line time and distance; it does not track airline schedules. At 10,442 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 13h 23m 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.
