Due to congestion of airport facilities including runways and terminal facilities around the world a system was developed to aid in the efficient usage of the available resources. The International Air Transport Association (IATA) developed a system to allocate airport slots in a worldwide agreed format according the Standard Schedules Information Manual (SSIM). Slots are allocated in accordance with guidelines set out in IATA's Worldwide Slot Guidelines (WSG). Airports throughout the world are categorised as either Level 1 (Non-Coordinated Airport), Level 2 (Schedules Facilitated Airport) and Level 3 (Coordinated Airport). Additionally, in some states or areas, such as in the European Union, legally binding regulations must be observed. They take precedence. WWACG members and associate members execute their activities on the basis of the WSG, as well as national and local rules. About 300 airports worldwide are coordinated to (Level 3) or schedule facilitated (Level 2) standards.
The WWACG members play a vital role in the air transport activities by assuring that airline schedules meet the capacity requirements at the busiest airports worldwide. Coordinators and schedule facilitators allocate slots to airlines by approving or making offers to their planned schedules (Level 3) or by making recommendations to their schedules at (Level 2) Airports. This process by the WWACG members ensures the best utilisation of the scarce resources at the airports whilst providing the best scheduling opportunities to the air carriers. This planning process reduces the excess demand situations at the airports during peak hours and helps to prevent lengthy delays.
All of our members and associate members have been officially approved by their governments or appointed by an appropriate authority as coordinators or schedule facilitators. They have detailed knowledge of slot allocation or schedules facilitation and act in a neutral, non-discriminatory, and transparent manner.
Most air carriers continue to grow steadily in most areas of the world, and there is no sign that the growth rate will slow down on a longer term view. This demand has challenged the airports to expand their facilities to keep up with the strong growth rates, but in many areas growth potential is limited. Consequently, the work of coordinators and schedule facilitators has become more complex, and there are no signs that this trend will be reversed in the future.
I hope that you will find this site interesting and informative. Details about our organisation, its role and its responsibilities can be found by exploring our webpages.
