ATA e-Business Specifications

For over forty years, the commercial aviation industry has worked together through a joint international effort to establish specifications for improving business processes and information exchange. Administered and published by the Air Transport Association (ATA) e-Business Program, these international specifications have evolved to meet the changing needs of the industry and to embrace the latest technological advances in information exchange (see Change Request Process). As a result, airlines and suppliers have seen dramatic improvements in data efficiency, security and consistency, and have experienced a significant reduction in the time required for delivery and retrieval of operationally critical information. The following is a list of specifications developed and maintained by the ATA e-Business Program. 

Members of the ATA e-Business Program may gain immediate access to all these specifications at no additional cost.
