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 | 24h 23m | 24h 48m |
| Narrowbody jet (A320, 737) | 780 km/h | 17h 12m | 17h 37m |
| Widebody jet (777, 787, A350) | 900 km/h | 14h 54m | 15h 19m |
| Private jet (Gulfstream) | 850 km/h | 15h 47m | 16h 12m |
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 Houston to Hong Kong?
A non-stop flight from Houston (IAH) to Hong Kong (HKG) takes about 17h 05m. The great-circle distance is 13,413 km (8,334 miles, 7,242 nautical miles), flying north-west on an initial bearing of 328°.
How far is Houston from Hong Kong?
13,413 kilometres in a straight line over the earth's surface — 8,334 miles or 7,242 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 IAH and HKG?
This page calculates the direct-line time and distance; it does not track airline schedules. At 13,413 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 17h 05m 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.
