Hong Kong to Miami
18h 22mgate to gate
The flight from Hong Kong International Airport (HKG) to Miami International Airport (MIA) covers 14,451 km (8,979 miles) and takes approximately 18h 22m gate to gate for a typical jet.
The route heads north on an initial great-circle bearing of 17°, passing near 74.4° N, 169.4° W 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: 14,451 km.
- Airborne time = that distance ÷ 805 km/h, a representative jet cruise speed: 17h 57m.
- Add a flat 25 minutes for pushback, taxi, climb, descent and taxi-in — the reason a 400 km hop is never half an hour: 18h 22m gate to gate.
- Winds, aircraft type and airline schedule padding are not modelled. The cruise-speed table shows how much that assumption is worth.
14,451 km / 805 km/h = 17h 57m airborne
+ 25 min ground = 18h 22m 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 | 26h 16m | 26h 42m |
| Narrowbody jet (A320, 737) | 780 km/h | 18h 32m | 18h 57m |
| Widebody jet (777, 787, A350) | 900 km/h | 16h 03m | 16h 29m |
| Private jet (Gulfstream) | 850 km/h | 17h 00m | 17h 25m |
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 Miami?
A non-stop flight from Hong Kong (HKG) to Miami (MIA) takes about 18h 22m. The great-circle distance is 14,451 km (8,979 miles, 7,803 nautical miles), flying north on an initial bearing of 17°.
How far is Hong Kong from Miami?
14,451 kilometres in a straight line over the earth's surface — 8,979 miles or 7,803 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 MIA?
This page calculates the direct-line time and distance; it does not track airline schedules. At 14,451 km the route is at the extreme end of what any airliner can fly non-stop, so a connection is likely. Check an airline or booking site for what is actually scheduled.
What should I expect on a 18h 22m 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.
