What's new

The Airline Coding Directory is now available as a Windows desktop application.This new efficient web download version allows IATA to update the information such as new airlines, designators and location identifiers on a more frequent basis, i.e. from two times a year to 12 times a year.

This improved application has all the information available in the printed version. In addition, it now features an update function which allows monthly updates that includes, not only the bulletins, but also a complete refresh of the coding tables & directory making your searches more accurate. The industry therefore benefits from 12 updates per year, compared to two previously. The Monthly Bulletins in PDF are now pushed directly into the application. ACD is available as a single user license only; searching codes has never been easier!
