How it works
AzulAir works like any flight search — with a few important differences
AzulAir works as a full-featured flight aggregator, searching across hundreds of airlines and travel partners in real time. We compare prices, routes, layovers, and travel times just like the platforms you already trust. There are no exclusive fares or hidden markups — you see the same offers available elsewhere. This means you don’t need to change your booking habits or compromise on convenience. The difference is not how we search, but how we help you choose.
Not all flights are equal when it comes to environmental impact. We analyze factors such as aircraft type, route efficiency, number of layovers, and distance to estimate CO₂ emissions for each option. Flights with lower emissions are clearly highlighted, making sustainable choices easier to spot. In many cases, greener flights cost the same or only slightly more than less efficient alternatives. You stay in control — we inform, not force — so you can decide what matters most for each trip.
AzulAir earns a commission when you book a flight, just like other aggregators. A portion of that commission is allocated to trusted environmental organizations focused on reforestation and ecosystem restoration. This means your trip contributes to real-world climate action without increasing the ticket price. You don’t need to make separate donations or extra payments — the impact is built into the platform. Over time, small actions from many travelers add up to meaningful change.
Booking through AzulAir does not cost you more. Ticket prices are identical to those on other major flight search platforms. We don’t add “eco fees” or hidden surcharges to fund sustainability initiatives. Our mission is to make responsible travel accessible, not premium or exclusive. Choosing a lower-impact flight should be a better decision, not a more expensive one.
Your impact doesn’t disappear after booking. At the end of the year, you receive a personalized Eco Impact Report summarizing your travel footprint. It shows estimated CO₂ emissions, how much you saved by choosing greener routes, and how many trees were planted thanks to your flights. The report turns abstract sustainability into something tangible and measurable. It’s a simple way to see how everyday travel choices can lead to long-term impact.
