Houston to Tocumen

3h 58mgate to gate

The flight from George Bush Intercontinental Airport (IAH) to Tocumen International Airport (PTY) covers 2,856 km (1,775 miles) and takes approximately 3h 58m gate to gate for a typical jet.

The route heads south-east on an initial great-circle bearing of 141°, passing near 19.7° N, 86.8° 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: 2,856 km.
  3. Airborne time = that distance ÷ 805 km/h, a representative jet cruise speed: 3h 33m.
  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: 3h 58m 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.
2,856 km / 805 km/h = 3h 33m airborne
            + 25 min ground = 3h 58m 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 Houston to Tocumen?

A non-stop flight from Houston (IAH) to Tocumen (PTY) takes about 3h 58m. The great-circle distance is 2,856 km (1,775 miles, 1,542 nautical miles), flying south-east on an initial bearing of 141°.

How far is Houston from Tocumen?

2,856 kilometres in a straight line over the earth's surface — 1,775 miles or 1,542 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 PTY?

This page calculates the direct-line time and distance; it does not track airline schedules. At 2,856 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.
