Flight Delay Reason and Flight Cancellation Reason API

Advancing Aviation: The Flight Delay Reasons API

The Flight Delay API sets our application apart by providing crucial, real-time data on flight delays. This API’s insights, including common delay causes like air traffic control issues, weather conditions, bird strikes, and mechanical problems, can be effectively used in various ways. They can enhance airport information displays, improve passenger notification systems, and bolster analytical efforts for better operational planning. Such detailed information extends beyond just informing passengers, it also offers valuable statistical data, streamlining overall flight and travel management processes

Access to the Complete Aviation Edge Database With the Flight Cancellation API Key

Aviation Edge does not only focuses flight delays and cancellations but complete aviation data with many features that will amaze you! 

We aggregate our data from our multiple data partners around the world and present it to you via various APIs that each focus on a specific subject.

The APIs mainly include:

  • Static Data: Stable data which does not frequently change, such as information regarding a certain airport and/or airline.
  • Dynamic Data: Ever-changing data which is frequently in need of confirmation such as the flight-tracking itself and the airport schedules.

Both the static data and the dynamic data are updated at all times in accordance with the information constantly gathered in our database. 

Prefer the data as a file rather than via the API? The complete static data is available as separate standalone databases in Excel, SQL and CSV formats, too. All three are included in any purchase.

Aviation Edge currently provides its clients with Satellite Tracker API, Real-Time Flight Tracker API, Nearby Service API, Routes API, Schedules API, Autocompletion Service API as dynamic data; and Historical Schedules API, Airlines API, Airplanes API, Airport API, City API, Country API and Taxes API as static data.
