Subscribe to OAG Flight Info Alerts to receive real-time gate, delay, and cancellation push events

Steps

1. Authenticate with the OAG Developer Portal to obtain your API key; review the Flight Info Alerts product tier for your required coverage (global vs regional) and update frequency.
2. Configure an alert subscription via the OAG API specifying the filter criteria: carrier code, departure airport, or specific flight number range; set the delivery method to HTTP push (webhook) or configure the event hub endpoint.
3. Implement the receiving webhook: OAG pushes JSON events containing flight_id, event_type (e.g., DELAY, CANCELLATION, GATE_CHANGE), the affected departure/arrival times, and the new values.
4. On receipt of a CANCELLATION or significant DELAY event (threshold configurable), look up affected bookings in your system by matching the carrier + flight_number + departure_date composite key.
5. Trigger downstream passenger notifications and, where applicable, initiate the IROPS or refund workflow based on the event type and delay magnitude.
6. Reconcile the OAG event timestamps against the booking departure times using UTC — OAG reports all times in UTC with a utc_offset field for local time reconstruction.
