Cancún to São Paulo
8h 37mgate to gate
The flight from Cancún International Airport (CUN) to São Paulo/Guarulhos–Governor André Franco Montoro International Airport (GRU) covers 6,603 km (4,103 miles) and takes approximately 8h 37m gate to gate for a typical jet.
The route heads south-east on an initial great-circle bearing of 136°, passing near 1.3° S, 66.9° W 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: 6,603 km.
- Airborne time = that distance ÷ 805 km/h, a representative jet cruise speed: 8h 12m.
- Add a flat 25 minutes for pushback, taxi, climb, descent and taxi-in — the reason a 400 km hop is never half an hour: 8h 37m gate to gate.
- Winds, aircraft type and airline schedule padding are not modelled. The cruise-speed table shows how much that assumption is worth.
6,603 km / 805 km/h = 8h 12m airborne
+ 25 min ground = 8h 37m 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 | 12h 00m | 12h 25m |
| Narrowbody jet (A320, 737) | 780 km/h | 8h 28m | 8h 53m |
| Widebody jet (777, 787, A350) | 900 km/h | 7h 20m | 7h 45m |
| Private jet (Gulfstream) | 850 km/h | 7h 46m | 8h 11m |
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 Cancún to São Paulo?
A non-stop flight from Cancún (CUN) to São Paulo (GRU) takes about 8h 37m. The great-circle distance is 6,603 km (4,103 miles, 3,565 nautical miles), flying south-east on an initial bearing of 136°.
How far is Cancún from São Paulo?
6,603 kilometres in a straight line over the earth's surface — 4,103 miles or 3,565 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 CUN and GRU?
This page calculates the direct-line time and distance; it does not track airline schedules. At 6,603 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 8h 37m 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.
