Worldwide Airport Slots

Each year, over 1.5 billion passengers - 43% of global traffic - depart from over 200 slot coordinated airports. The number of slot coordinated airports is expected to grow significantly due to a lack of expansion in airport infrastructure to cope with increasing demand.

IATA is at the forefront of ensuring a fair, neutral and transparent allocation of airport slots at the worlds’ most congested airports through the application of the Worldwide Slot Guidelines (WSG).

By having the same set of rules at both the departure and arrival airport, the WSG allow airlines to plan their whole network and schedule, and provide choice and connectivity to the passengers.       

Our Role Workgroups Strategic Review Training FAQs Position Papers

IATA provides the global air transport industry with the Worldwide Slot Guidelines (WSG), a single set of guidelines for airport slot management and allocation. The slot planning process is the essential back bone to allow the industry to plan operations to the world’s most congested airports, avoiding what would otherwise be chaos. 

IATA is actively involved in a range of activities including:

  • Working with governments and regulators to promote and align policy with the WSG.
  • Supporting the implementation of one single global standard.  
  • Running the twice-yearly Slot Conference to allow airlines and coordinators to meet face-to-face to review their slot portfolio and finalize their future schedules.
