Flight Plan - Delay Code IATA

The IATA Delay Code is a system used in flight planning to provide standardized reasons for flight delays. These codes are assigned by airlines to indicate the cause of a delay, allowing for easier tracking and analysis of delay trends.

There are numerous IATA Delay Codes, with each code representing a specific reason for the delay. Some examples include:

  • AC : Aircraft Change
  • ATC : Air Traffic Control
  • WX : Weather
  • MX : Maintenance
  • PD : Passenger Delay
  • SS : Security Delay

By using these codes, airlines can more easily identify patterns of delays and work to address the root causes of these issues.
