For the purposes of adjusting and confirming flight schedules, the air transport industry recognizes three different categories of airports, depending on the relationship between operational demand and airport capacity.
• Level 1 airport (or Non-coordinated airports): Airports whose capacity is enough to meet airlines’ air transport demand.
• Level 2 airports (or Schedules Facilitated airports): Airports where airlines’ air transport demand is close to the airport’s capacity and where there is a potential risk of congestion at certain times. In these airports voluntary cooperation between airlines may be necessary, and there will be a Schedules Facilitator to organize and adjust the schedules as needed to avoid congestion.
• Level 3 airports (or Co-ordinated airports): Airports where airlines’ air transport demand exceeds the airport capacity during significant periods and the situation cannot be resolved in the short term. In these airports there will be a Slot Coordinator, and all airlines must have a slot authorized by the Slot Coordinator in order to land or take off at the airport (except State flights, emergency landings and humanitarian flights).
