# Flight

Passenger flights are integral to global connectivity, yet they contribute significantly to carbon emissions. Factors like aircraft model, flight duration, altitude, and even in-flight services can influence a plane's carbon footprint, rendering general estimations inadequate for precise calculations.

With SQUAKE's precision-based model, these intricacies are seamlessly integrated. This ensures that airlines and travelers have an accurate measure of the carbon footprint for each journey. Adopting SQUAKE allows for informed decisions towards sustainability, promoting eco-friendly skies for all.

For **multi-leg itineraries** described as a single hyphen-separated airport chain (for example `BER-FRA-JFK`) instead of origin and destination, see [**Flight: Routing (multi-leg)**](/api-calculations-request-response/travel/flight/flight-routing.md).
