Good to know

How is the flight time estimated?

We calculate the great-circle distance between the two airports and divide it by a typical cruising speed, adding time for take-off and landing. Real flights vary with wind, routing and aircraft.

How is CO2 calculated?

We use an average of about 0.129 kg of CO2 per passenger per mile in economy. It is an estimate for comparison, not an official figure.
