Porto to Narita
13h 57mgate to gate
The flight from Francisco de Sá Carneiro Airport (OPO) to Narita International Airport (NRT) covers 10,889 km (6,766 miles) and takes approximately 13h 57m gate to gate for a typical jet.
The route heads north-east on an initial great-circle bearing of 25°, passing near 71.3° N, 73.7° E 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: 10,889 km.
- Airborne time = that distance ÷ 805 km/h, a representative jet cruise speed: 13h 32m.
- Add a flat 25 minutes for pushback, taxi, climb, descent and taxi-in — the reason a 400 km hop is never half an hour: 13h 57m gate to gate.
- Winds, aircraft type and airline schedule padding are not modelled. The cruise-speed table shows how much that assumption is worth.
10,889 km / 805 km/h = 13h 32m airborne
+ 25 min ground = 13h 57m 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 | 19h 48m | 20h 13m |
| Narrowbody jet (A320, 737) | 780 km/h | 13h 58m | 14h 23m |
| Widebody jet (777, 787, A350) | 900 km/h | 12h 06m | 12h 31m |
| Private jet (Gulfstream) | 850 km/h | 12h 49m | 13h 14m |
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 Porto to Narita?
A non-stop flight from Porto (OPO) to Narita (NRT) takes about 13h 57m. The great-circle distance is 10,889 km (6,766 miles, 5,880 nautical miles), flying north-east on an initial bearing of 25°.
How far is Porto from Narita?
10,889 kilometres in a straight line over the earth's surface — 6,766 miles or 5,880 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 OPO and NRT?
This page calculates the direct-line time and distance; it does not track airline schedules. At 10,889 km the route is within reach of long-range widebodies, though not every city pair is served non-stop. Check an airline or booking site for what is actually scheduled.
What should I expect on a 13h 57m 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.
