Range and fuel stops
Not every jet can fly every route nonstop. With reserves, light jets reach about 2,800 km, super midsize jets around 5,500 km and ultra long range jets more than 11,000 km. If the destination is further away, the operator plans a fuel stop of roughly 45 minutes.
For transatlantic flights or routes to Asia the larger class often pays off: it costs more per hour but saves stops and therefore time.
- Turboprop / PC-12: up to approx. 2,200–2,800 km
- Light jet: up to approx. 2,800 km
- Midsize jet: up to approx. 3,700 km
- Super midsize jet: up to approx. 5,500 km
- Heavy jet: up to approx. 7,000 km
- Ultra long range: 11,000 km and more
Calculating the distance between airports
We calculate distance as the great-circle distance — the shortest path over the globe — and also show it in nautical miles, the standard unit in aviation. Because aircraft follow airways and approach procedures, the distance actually flown is slightly longer; the flight time already includes this.
How we calculate
- Distance: great-circle calculation from both airports’ coordinates, plus 5% for airways and approach procedures.
- Flight time: distance flown divided by the class’s typical cruise speed, plus 15 minutes for climb and descent and 10 minutes of taxi per take-off and landing.
- Fuel stops: added once the route exceeds practical range with reserves, 45 minutes on the ground per stop.
- Wind is not included. Strong headwinds (typically westbound across the Atlantic) can add 10–15% to flight time; tailwinds shorten it.
