An airline operating a flight will need to have a slot at both the origin airport and the destination airport.

What do you know about 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.
