Houston to Dubai
16h 43mgate to gate
The flight from George Bush Intercontinental Airport (IAH) to Dubai International Airport (DXB) covers 13,125 km (8,156 miles) and takes approximately 16h 43m gate to gate for a typical jet.
The route heads north-east on an initial great-circle bearing of 30°, passing near 64.1° N, 15.3° 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: 13,125 km.
- Airborne time = that distance ÷ 805 km/h, a representative jet cruise speed: 16h 18m.
- Add a flat 25 minutes for pushback, taxi, climb, descent and taxi-in — the reason a 400 km hop is never half an hour: 16h 43m gate to gate.
- Winds, aircraft type and airline schedule padding are not modelled. The cruise-speed table shows how much that assumption is worth.
13,125 km / 805 km/h = 16h 18m airborne
+ 25 min ground = 16h 43m 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 | 23h 52m | 24h 17m |
| Narrowbody jet (A320, 737) | 780 km/h | 16h 50m | 17h 15m |
| Widebody jet (777, 787, A350) | 900 km/h | 14h 35m | 15h 00m |
| Private jet (Gulfstream) | 850 km/h | 15h 27m | 15h 52m |
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 Houston to Dubai?
A non-stop flight from Houston (IAH) to Dubai (DXB) takes about 16h 43m. The great-circle distance is 13,125 km (8,156 miles, 7,087 nautical miles), flying north-east on an initial bearing of 30°.
How far is Houston from Dubai?
13,125 kilometres in a straight line over the earth's surface — 8,156 miles or 7,087 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 DXB?
This page calculates the direct-line time and distance; it does not track airline schedules. At 13,125 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 16h 43m 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.
