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.

Executive Summary

International Transport Forum

Expanding airport capacity is difficult in large urban areas. Expansion of existing airports is usually constrained by community agreements on noise and local air pollution and by a shortage of land. Finding sufficient land, at feasible prices, to develop or relocate major airports on green-field sites within a reasonable distance of city centres is often very difficult. Creating land for airports in locations less sensitive to noise and land-use conflicts, for example through offshore or estuarine land reclamation, is expensive and most new sites will require extensive investments in surface transport links to city centres. Furthermore, moving an airport imposes costs on airlines and their users as well as on activities located close to and dependent on proximity to the existing one. In multi-airport regions, options for expansion at one airport will impact the others and airlines, operating in increasingly competitive markets, may respond differently to alternative ways in which the region’s airport capacity might be increased.
