Charlotte to Dulles

1h 04mgate to gate

The flight from Charlotte Douglas International Airport (CLT) to Washington Dulles International Airport (IAD) covers 517 km (321 miles) and takes approximately 1h 04m gate to gate for a typical jet.

The route heads north-east on an initial great-circle bearing of 36°, passing near 37.1° N, 79.2° W at its midpoint.

How this is worked out

  1. Take both airports' published coordinates from OurAirports — nothing here is scraped from another flight site.
  2. Great-circle distance by haversine on a mean earth radius of 6,371.0088 km: 517 km.
  3. Airborne time = that distance ÷ 805 km/h, a representative jet cruise speed: 39m.
  4. Add a flat 25 minutes for pushback, taxi, climb, descent and taxi-in — the reason a 400 km hop is never half an hour: 1h 04m gate to gate.
  5. Winds, aircraft type and airline schedule padding are not modelled. The cruise-speed table shows how much that assumption is worth.
517 km / 805 km/h = 39m airborne
            + 25 min ground = 1h 04m 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.

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 Charlotte to Dulles?

A non-stop flight from Charlotte (CLT) to Dulles (IAD) takes about 1h 04m. The great-circle distance is 517 km (321 miles, 279 nautical miles), flying north-east on an initial bearing of 36°.

How far is Charlotte from Dulles?

517 kilometres in a straight line over the earth's surface — 321 miles or 279 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 CLT and IAD?

This page calculates the direct-line time and distance; it does not track airline schedules. At 517 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.
