Learn more about how we calculate the volume of emissions from a flight.
In addition to calculating individual trips, you can also make a one-off contribution, using either cash or your Asia Miles.
Your cash donation, in the range of HK$10 to HK$999,999, should be rounded off to the nearest dollar.
For Asia Miles, the redemption range is 100 to 999,999 miles.
Learn more about the flights that can be offset for different contribution amounts.
I would like to make the following one-off contribution to the FLY greener project.
