Airport IATA Delay Code

Delay Codes

Aircraft that are grounded at airports due to unforeseen circumstances can be costly to the operator.

IATA delay codes are codes that are used in movement messages sent via SITA Telex or emails from the Departure airport to the Destination airport, they were created by the International Air Transport Association to help airlines standardize why a commercial flight left late from its departure airport in order to determine who is responsible for the delay and who will be penalized

Delay codes starting from 01 to 05 are used for internal airline purpose they can be used freely by airline companies to determine particular application fields
