Expanding Airport Capacity in Large Urban Areas

image of Expanding Airport Capacity in Large Urban Areas

Expanding airport capacity in large metropolitan areas is difficult. Community agreements on noise constrain growth at existing airports. Land prices can be prohibitive for relocating airports. Most new sites require extensive investment in surface transport links to city centres. In multi-airport regions, options for expansion at the airports are to an extent interdependent, complicating assessment of whether to build new runways.

Many major airports are hubs for network carriers at the same time as serving a large local market. The complementarity between these functions may be a prerequisite for viable network operations, suggesting that distributing services over multiple airports instead of expanding the main hub would be costly. Hub airports and their network carriers often compete with hubs in neighbouring regions. The strategies of network carriers and potential new entrants to this part of the market need to be taken into account in assessing future demand for airport capacity. The requirements of low cost and other point-to-point carriers are equally important, but different.

This report reviews international experience in reconciling planning and environmental constraints with demand for airport capacity and the potential benefits in terms of productivity and growth from developing international airline services. Experience is compared in London, New York, Tokyo, Osaka, Sydney and in Germany’s main airports with particular attention to the dynamics of airline markets and implications for airport planning in multi-airport cities.

Airport capacity expansion strategies in the era of airline multi-hub networks

International Transport Forum

Many major airports are hubs for network carriers at the same time as serving a large local market. The complementarity between these functions is often seen as a prerequisite for viable hub operations, suggesting that spreading the hub network over multiple airports can be very costly and damages the corner stone of the hub operation: the creation of scope and density economies. The objective of this paper is to add to the understanding of the network strategies followed by (multi)hub network carriers; and to draw conclusions from this understanding for the capacity expansion strategies of airports, in particular for the London Metropolitan Area
