A system and method are disclosed for communicating transactional and informational messages among air travel service providers and other participants. The technique implements a public protocol in a network having a service oriented architecture. A message in a source format is converted to a public format message with a payload, wherein the payload is the message. The open source message is parsed and communicated over a network, such as the Internet Protocol network, to a switch. The switch authenticates the message, extracts the payload, and communicates the message to the destination, where the message may be converted into a destination format and communicated to a user interface. The message may be processed by the switch and/or the destination to obtain statistical and/or other useful data.
