Steps
Obtain an Application ID and Application Key (appId/appKey) for the FlightStats/Cirium Schedules API — this is a distinct product and credential set from Cirium's Flight Status API.
To search by route, call the schedules-by-route endpoint with the departure and arrival airport codes and the arrival date.
To search by flight, call the schedules-by-flight endpoint with the carrier code, flight number, and arrival date.
Pass appId and appKey either as query parameters or as header parameters, depending on which authentication mode your subscription is configured for.
Treat the response as published/planned schedule data, not live operational status — use Cirium's separate Flight Status API for real-time delay or gate information.
Known gotchas
Schedules and Flight Status are separate Cirium products with separate data — schedules reflect the published/planned flight, not live operational status.
Authorization failures commonly come from mismatched appId/appKey pairs or sending them in the wrong place (query vs. header) for your account's configured auth mode.
