The total flight duration from Ashburn, VA to Houston, TX is 2 hours, 50 minutes.
This is the average in-air flight time (wheels up to wheels down on the runway) based on actual flights taken over the past year, including routes like IAD to IAH. It covers the entire time on a typical commercial flight including take-off and landing.
If you're planning a trip, you should also factor in extra time for the plane to pull back from the gate and taxi to the runway, as well as reaching the destination gate after landing. If you include this extra time on the tarmac, the average total elapsed time from gate to gate flying from Ashburn, VA to Houston, TX is 3 hours, 15 minutes.
Finally, pilots might want to estimate the flight time using an average flight speed for a commercial airliner of 500 mph, which is equivalent to 805 km/h or 434 knots. If you don't add any extra time to increase or decrease speed for take-off and landing, then at constant speed your flight time would be 2 hours, 24 minutes.
