We neutralize at least 100% of your flight CO2 emissions !

We only use trees and other 'natural climate solutions' !

We do this automatically and FREE of any extra cost or effort to you !

  fly-eco.com is unique and easy to use !

Step 1:  Use our flight search tool below to search and book with 700+ airlines and travel agents !

Step 2:  We plant or save at least 10 trees to offset 100% + the CO2 of your flight, free of extra costs to you!

Step 3:  We can reduce the eco- impact of your hotel and car hire if you search & book them via our site!


Our flight search tool finds similar flights and offers as other traditional flight comparison sites, but we uniquely re-invest at least 50% (rising to 80%) of any surplus revenue into additional 'natural climate solutions' schemes which can absorb your additional or historic CO2 emissions!


Because we are an environmental-purpose organisation, no for-profit flight search company has the vision nor the ability to prioritise and redirect their revenues and profits in such a massive way!

Existing 'kayak.com' user ?

 If you're already a kayak.com user and you prefer their interface, you can still search for flights using kayak.com using our dedicated link below.


Through kayak.com we receive less revenue and so we can't guarantee to neutralize 100% of the CO2 emissions of all flight bookings, however, we can still plant at least 3 trees free of cost to you... each time you search from this page using the kayak.com box below:


If you use kayak.com, please remember that we can only plant trees if you always start your search from this page https://www.fly-eco.com/flights-kayak, so please bookmark it !

  • Tens of thousands of trees already planted and saved!

  • Millions more trees planned!

  • Our goal is to lead in 'natural climate solutions' for aviation!
