How to use this tool

  1. Enter the flight distance in kilometres (available on your booking page).
  2. Enter the aircraft's cruising speed — 900 km/h is a good default for most commercial jets.
  3. The calculator returns the estimated flight duration in hours and minutes.
  4. Add 20–40 minutes for taxiing, take-off, and landing not included in cruise time.

Estimate how long your flight will take based on the route distance and typical cruising speed.

Formula

Total flight time (h) = distance (km) ÷ speed (km/h)

Hours (whole) = floor(total)  |  Minutes = round((total − floor(total)) × 60)

How it works

This estimator divides the route distance by the aircraft's cruising speed to get total flight time in decimal hours, then breaks that into whole hours and rounded minutes. It models only the cruise phase and does not account for taxi time, take-off, landing, air traffic control holds, or wind. Use it as a rough planning guide rather than an exact schedule.

Worked example

Worked example

  1. Distance = 1000 km, cruising speed = 900 km/h
  2. Total time = 1000 ÷ 900 ≈ 1.1111 hours
  3. Whole hours = floor(1.1111) = 1 h
  4. Minutes = round((1.1111 − 1) × 60) = round(6.667) = 7 min

Total flight time = 1.11 h (1 hour 7 minutes)

Key terms

Cruising speed
The steady airspeed maintained by an aircraft during the main portion of a flight, typically expressed in km/h or knots.
Block time
Total elapsed time from gate departure to gate arrival, including taxi, take-off, cruise, and landing — longer than estimated cruise time.
Great-circle route
The shortest path between two points on a sphere; the distance used for flight planning is usually the great-circle distance.
Headwind / tailwind
Winds blowing against or with the aircraft's direction of travel; they increase or decrease effective ground speed and actual flight time.

Frequently asked questions

How is flight time calculated?
Flight time = distance ÷ cruising speed. A 1000 km route at 900 km/h takes about 1 hour 7 minutes of cruise time. Add extra time for ground operations.
What is a typical commercial jet speed?
Most commercial jets cruise between 800 and 950 km/h (500–590 mph). Long-haul wide-bodies like the Boeing 787 or Airbus A350 typically cruise at around 900 km/h.
