Worldwide Slot Guidelines

The Worldwide Slot Guidelines (WSG) are the foundation upon which the global slot allocation process works for the benefit of airlines, airports and the passengers. IATA ensures it evolves with the industry to continue to optimize the use of scarce airport capacity for all. The WSG is built on the pillars of transparency, flexibility, certainty, consistency and sustainability. 

Thanks to continual update  and revision,  the WSG  represent the globally accepted  best practice for governments and airport regulators. The guidelines ensure  that slots at  capacity-constrained airports  around the world  are allocated  to airlines using consistent policies, principles and processes.

A living document, WSG is reviewed on a regular basis to keep up with industry and regulatory changes.
