New York to Porto

7h 03mgate to gate

The flight from John F. Kennedy International Airport (JFK) to Francisco de Sá Carneiro Airport (OPO) covers 5,333 km (3,314 miles) and takes approximately 7h 03m gate to gate for a typical jet.

The route heads north-east on an initial great-circle bearing of 67°, passing near 45.8° N, 41.4° 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: 5,333 km.
  3. Airborne time = that distance ÷ 805 km/h, a representative jet cruise speed: 6h 37m.
  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: 7h 03m 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.
5,333 km / 805 km/h = 6h 37m airborne
            + 25 min ground = 7h 03m 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 New York to Porto?

A non-stop flight from New York (JFK) to Porto (OPO) takes about 7h 03m. The great-circle distance is 5,333 km (3,314 miles, 2,880 nautical miles), flying north-east on an initial bearing of 67°.

How far is New York from Porto?

5,333 kilometres in a straight line over the earth's surface — 3,314 miles or 2,880 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 JFK and OPO?

This page calculates the direct-line time and distance; it does not track airline schedules. At 5,333 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.

What should I expect on a 7h 03m 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.

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.
