Houston to Dallas-Fort Worth
52mgate to gate
The flight from George Bush Intercontinental Airport (IAH) to Dallas Fort Worth International Airport (DFW) covers 362 km (225 miles) and takes approximately 52m gate to gate for a typical jet.
The route heads north-west on an initial great-circle bearing of 334°, passing near 31.4° N, 96.2° 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: 362 km.
- Airborne time = that distance ÷ 805 km/h, a representative jet cruise speed: 27m.
- Add a flat 25 minutes for pushback, taxi, climb, descent and taxi-in — the reason a 400 km hop is never half an hour: 52m gate to gate.
- Winds, aircraft type and airline schedule padding are not modelled. The cruise-speed table shows how much that assumption is worth.
362 km / 805 km/h = 27m airborne
+ 25 min ground = 52m 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 | 39m | 1h 05m |
| Narrowbody jet (A320, 737) | 780 km/h | 28m | 53m |
| Widebody jet (777, 787, A350) | 900 km/h | 24m | 49m |
| Private jet (Gulfstream) | 850 km/h | 26m | 51m |
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 Dallas-Fort Worth?
A non-stop flight from Houston (IAH) to Dallas-Fort Worth (DFW) takes about 52m. The great-circle distance is 362 km (225 miles, 195 nautical miles), flying north-west on an initial bearing of 334°.
How far is Houston from Dallas-Fort Worth?
362 kilometres in a straight line over the earth's surface — 225 miles or 195 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 DFW?
This page calculates the direct-line time and distance; it does not track airline schedules. At 362 km the route is comfortably within range of a non-stop service if an airline chooses to fly it. Check an airline or booking site for what is actually scheduled.
Airport coordinates from OurAirports (public domain). Distance is a great-circle calculation; flight time uses the model described on the method page. Flight times are great-circle estimates for planning only — always check the airline's published schedule.
