- 1. There is a natural ebb and flow of economic activity that, at times, can lead to surges in air traffic during certain periods or in certain locations. These surges place an increased demand on the air traffic Capacity is the number of flights that can be handled safely and efficiently in a sector or location during a given time period. Demand is the number of flights that intend to fly in a sector or location during a given time period. If Demand exceeds Capacity, either the capacity or the demand will need to be adjusted and additionally, provide alternatives to customers However, sometimes capacity cannot be increased, so adjusting demand is needed

This could result in slots being issued and/or rerouting of flights Canso offers practical advice on how ANSPs and airport operators can progress their integration initiatives and boost operational performance Air traffic flow management (ATFM) and airport collaborative decision making (A- CDM) are collaborative processes aimed at improving efficiency and optimising resources in airspace and at airports

- 9. : Higher fares for late bookings When booking well in advance, it can still be possible to secure cheap air fares at congested airports. However at congested airports there are less of these opportunities available, and air fares can spike more steeply, as the date of travel approaches. More premium tickets Airlines also respond by dedicating more of their aircraft capacity to premium seats at congested airports i.e. more expensive first- class and business-class seats. More passengers have to purchase premium seats if they wish to fly from these airports, and a reduced number of economy-class seats are made available IMPACTS AIR FARES
- 10. : Higher Average Frequency to Fewer Destinations At congested airports, airlines focus on high-frequency services on high-demand routes. A subset of passengers will pay extra for regular and convenient departure/arrival times. In effect the airline is enacting the equivalent of airport charges peak pricing
