Coordination Principles


The coordination process between airlines and airport coordinators is described in the IATA Worldwide Slot Guidelines (WSG) which contains a set of procedures and time frames to provide guidance for the management of the allocation of scarce resources at busy airports. The communication between airlines and coordinators is outlined in the IATA Standard Schedules Information Manual (SSIM) which is constituted under IATA Passenger Services Conference Recommended Practice 1761b that was declared effective 1 July 1972.  Standard message formats have been agreed to allow airlines, airport coordinators and schedule facilitators to exchange airport coordination and schedule movement information electronically. The message formats are integrated into an iterative (sequential) set of request and reply messages and have been designed to provide as much clarity as possible for the message users. The received message details can be processed either by computer or by manual methods. The rules for the use and composition of the messages, together with detailed specifications and examples, are explained in chapter 6 of the SSIM.
