I need historical flight data api, is that possible with flighaware? I need to know if there was a delay for example.
Historical data (beyond 14 days) is not available through FlightXML.
If you require past data for a small number of flights, then you visit our website and click the “Purchase entire flight history” button present at the bottom of the flight page of any aircraft to download it in CSV format. However, for larger numbers of aircraft if will be more economical to contact our commercial data services department and order a “custom report” that is tailored to your needs: https://flightaware.com/commercial/reports/
