Example response

Field names match the live API. This flight only shows the shape. It is not a live result.

{ "success": true, "data": [ { "airline_iata": "AA", "flight_iata": "AA100", "flight_number": "100", "dep_iata": "FSD", "dep_time": "2024-03-15 08:00", "dep_actual": "2024-03-15 08:22", "dep_delayed": 22, "status": "active" } ] }

That URL still says YOUR_ACCESS_KEY. A 7-day trial replaces it with a real key and returns the FSD departures that are late right now, in the JSON above. After the trial, Starter is $24.99/mo.
