The Flights are one way therefore a return flight should be entered as two. Double leg flights such as to Australasia should be entered as two long haul flights in each direction.

Our flight calculator is based on the UK’s aviation emissions divided by the number of flights in each category. Given that any individual flight is impossible to quantify without knowing the type of aircraft the prevailing weather and the number of empty seats in each direction it is probably of greater accuracy than calculators that purport to calculate the exact emissions between two airports.

Regular rail travel (miles per week)
Regular bus travel (miles per week)
Domestic flights per year
European flights per year
Long haul flights per year
