Fly by impact

Lite Flights is not your normal flight search engine. We rank flights based on carbon emission not price or convenience. The lesser the better. This means modern aircrafts are ranked higher than older aircrafts. We have crafted a detailed emission model for each aircraft type and per route, we match these and show you the best options.

Not all fights are created equal

Air travel is a contributor to the atmosphere's dangerous CO2 levels, and emissions could triple by 2050. As the climate crisis deepens, the conflict between our need to fly and our responsibility to the planet escalates. We recognise that people will still fly, so we give you a choice that will make a difference.

Every saving helps

Our CO2 impact model is based on extensive research and our database covers the whole world and the vast majority of the world's airlines. This includes emission models on all aircraft types from the latest Airbus A350-1000 through to much older models such as the Boeing 747-400 and everything in-between. Our route data is updated daily along with regular improvements to our modelling of all aircraft and their respective CO2 emission.
