FAQ
Frequently asked questions
What average speed should I use for commercial jets?

Does this include taxi, takeoff, and landing time?
No, this estimates only the cruising flight time based on distance and speed.
Does this account for wind?
No, headwinds and tailwinds can meaningfully change actual flight time — this is a simplified estimate.
How do I find the great-circle distance between two cities?
Use a flight distance lookup tool or mapping service for the most accurate distance figure.
