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 | 19h 24m | 19h 49m |
| Narrowbody jet (A320, 737) | 780 km/h | 13h 41m | 14h 06m |
| Widebody jet (777, 787, A350) | 900 km/h | 11h 51m | 12h 16m |
| Private jet (Gulfstream) | 850 km/h | 12h 33m | 12h 58m |
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 Narita to Houston?
A non-stop flight from Narita (NRT) to Houston (IAH) takes about 13h 40m. The great-circle distance is 10,669 km (6,629 miles, 5,761 nautical miles), flying north-east on an initial bearing of 46°.
How far is Narita from Houston?
10,669 kilometres in a straight line over the earth's surface — 6,629 miles or 5,761 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 NRT and IAH?
This page calculates the direct-line time and distance; it does not track airline schedules. At 10,669 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 40m 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.
