Methods, systems, and computer program products for automatically issuing travel documents. Tasks relating to issuance of travel documents are generated by an originating application in response to booking a travel service. The tasks are received and stored in a first queue until a triggering event, such as the arrival of a time for issuance of a document. In response to the triggering event, a task in the first queue may be placed in a second queue for transmission to an issuing application. The documents to be issued may be determined based on records in a passenger name record (PNR) stored in a database. The PNR may be determined based on the task. The PNR may be updated with information indicating whether task processing was successful. In the event of an error, information indicating the cause of the error may be added to the PNR. |
