Worldwide Airport Slots

Each year, over 1.5 billion passengers - 43% of global traffic - depart from over 175 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

The Strategic Review of the WSG is a joint initiative of Airports Council International, IATA and Worldwide Airport Coordinators Group to ensure the improvement and optimization of the WSG, so that all stakeholders continue to benefit from one sustainable global slot process. Airlines, airport operators, and slot coordinators are fundamental partners in developing robust airport slot management policies. The review is based on the WSG principles of transparency, flexibility, sustainability, certainty, and consistency.

Objectives of the Strategic Review

  • Strengthen the principles of the WSG
  • Ensure policy and procedures remain relevant
  • Reinforce the benefits of the single global process
  • Better take advantage of new technologies
