Flight Tracking APIs
Tracking a flight can mean following the aircraft or following the schedule. ADS-B Exchange is the paid option for real-time and historical positions from crowdsourced receivers. Aviationstack and AirLabs report live flight status, routes and positions worldwide, both with free tiers. For a single airport, Schiphol and Swedavia publish real-time arrivals and departures, with Swedavia adding security queue times.

Choosing a Flight Tracking API
Is there a free Flight Tracking API?
Yes. Aviationstack, AirLabs and Swedavia Airports have a free tier alongside paid plans.
Which Flight Tracking APIs work without an API key?
All of them need a key or account. Aviationstack, AirLabs and Swedavia Airports give one out free when you sign up.
Can I use Flight Tracking APIs in a commercial project?
Swedavia Airports permits commercial use. ADS-B Exchange restricts it, for example to non-commercial or attributed use, so read the terms first.
