Compare Cheap Flights

FlyGRN in a nutshell: FlyGRN compares the lowest price of flight tickets from airlines and merchants in one place. Best of all, for each flight sold, we offset the carbon (CO2) emissions of your flight. We pay that with the fee for bringing you in as a customer. We do this because we think it is important that carbon offsetting happens. So you don’t have to pay anything extra for carbon offsetting. And because we compare more than six flight ticket sites at once, you usually also find the best price. So, start comparing the same flights including free CO2 compensation at FlyGRN.com.

Flights of FlyGRN more expensive? No, not at all!

Because offsetting your flight is done with our own income, your flight is often just as expensive as at other sites that compare flights. In some cases flights are even cheaper. That is possible because we search multiple airline ticket sites at once and choose the best flight prices for you.

Compare flight tickets with free carbon offsetting

Less than 1% of travelers offsets their flight’s carbon emissions. We therefore compensate part of your flight's carbon emissions with our own income from selling your flight tickets. We offset by supporting solar panel projects in India that displace fossil fuels. Could you imagine how many solar panels we can built if everyone would book their flight via FlyGRN? Oh, and yes, we also show train alternatives if there are any, since traveling by train is way more sustainable!

Why is carbon offsetting included in our flights?

We think it is important that more people compensate for their flight’s emissions, because although it is better not to fly, sometimes you have to. In those cases, carbon offsetting makes sense and the supported projects have a huge carbon reducing impact. The solar panel project in India that we support offers hundreds of thousands of people with clean energy. That is why we have chosen to pay for your carbon offsetting from our own pocket, from the margins that we earn from selling your flight. Compare flights now!
