The Scheduling Services are responsible for the development and maintenance of standards and procedures for the exchange of schedule data between airlines and airports and airport Coordinators and the bi-annual IATA Schedules Conferences.
The purpose of this voluntary assembly of both IATA and non-IATA airlines worldwide, is to provide a forum for the allocation of slots at fully coordinated airports (Level 3), and for the reaching of consensus on the schedule adjustments necessary to conform to airport capacity limitations (Level 2).
On behalf of the Conference IATA manages and publishes the Worldwide Scheduling Guidelines. These guidelines are developed in consultation with the airline and airport coordinator communities. They are intended to provide guidance on managing the allocation of scarce resources at airports on a fair, transparent and non-discriminatory basis.
