Performance measurement: a review of airports

This paper considers the past, present and future of airport performance measurement. The authors examine the changing nature of the performance measurement of airports. Airport performance measures are important for day to day business and operational management, regulatory bodies, Government and other stakeholders such as passengers and airlines. Measurement systems have been forced to develop in response to changing organisational contexts. With pressures for change coming from changing ownership patterns, an increased commercial focus, regulation, rapid passenger growth, increased concern for the natural environment and technical innovation, the experiences shared and lessons to be learnt highlighted in this paper will be of interest to both academics and practitioners.     

Modelling the effects of capacity constraints on air travellers’ airport choice

This paper analyses the effects of limited capacity on air travellers’ airport choice. The analysis is based on a market-segment specific airport choice model that accounts for limited capacities. The region of Stuttgart in Germany serves as a case study to examine the impact of limited airport capacity on air travellers’ airport choice. Air travellers’ choice depends on the supply of flights and accessibility of the airports in their choice set as well as on their preferences and willingness-to-pay. To elaborate the effects of limited airport capacity, scenarios relating to the capacity situation at airports serving the air travel demand of the Stuttgart region are analysed. This paper reveals the mutual dependence among airports. Capacity constraints at one airport cause spill-over effects and thus influence air travel demand served at other airports. In some cases this may even lead to new capacity constraints elsewhere.     

Managing New Zealand's airports in the face of commercial challenges

This paper explores commercial issues surrounding managing airports in New Zealand. Airport managers face pressures from changing airport–airline relationships, low cost airlines, proposed new airports and the growing importance of non-aeronautical revenues in achieving commercial goals. New Zealand's airports have moved from an operating environment within which all the principal airports were owned and managed by central government to one where airports are run as commercial entities under a variety of ownership structures. New Zealand has a high dependence on air transport and for its size, a very developed regional airport network.     

An empirical analysis of airport capacity expansion

Theoretical analyses of the impact of airport capacity expansion must model or make assumptions about the effect of capacity on demand, airline competition, aircraft types, fares and other characteristics of a given airport. In this paper, we use empirical data on historical schedules, fares, delays and demand for the busiest 150 airports in 2015 to examine the typical impact of historical capacity expansions. We find significant diversity in outcomes, with over half the expanded airports either using less than their pre-expansion capacity or remaining constrained even at post-expansion capacity by 2016. Many of the expected impacts, such as reductions in typical aircraft size, either do not materialise or are dominated by other effects (for example, recessions; airlines beginning or ending operations at an airport; changes in regulation). Behaviour on expansion is affected by slot control regulations and whether the airport is initially capacity-constrained. In particular, slot-controlled airports typically add new destinations and carriers on expansion rather than making significant changes to existing schedules.     

Airline strategies for aircraft size and airline frequency with changing demand and competition: A simultaneous-equations approach for traffic on the north Atlantic

Airport planners need to know the forecast demand on the facilities provided airside at airports. For this they need to know how airlines will deal with traffic in terms of the size of aircraft and frequency of service. In response to increasing demand, airlines may increase capacity by increasing the frequency of flights or they may choose to increase aircraft size. This may yield operating cost economies. If the airports they operate from are capacity constrained they will be limited in the extent that they can change frequency that will limit their ability to compete with the number of frequencies offered. Consequently, these airports are excluded as are major hubs as frequencies will be influenced by connecting passengers. Routes are identified on the north Atlantic that can be analysed and conclusions are suggested on the basis of three stage least-squares estimates for pooled time series-cross section data. An increase in passengers on the whole will result in a larger increase in frequency than in aircraft size but the impact of competition does not yield significant results due to the strategy of excluding certain categories of airport.     

Is increasing aircraft size common practice of airlines at congested airports?

If the overall demand for air transport grows, but additional airport capacity is not available at congested airports, we could assume that airlines will offer flights with more seats in order to cope with the demand. An analysis of frequency and average seat capacity developments at congested, and not yet congested airports, has shown that the hypothesis of bigger aircraft being used in congested situations is valid in most instances, although not at all airports. The objective of this paper is to report on an analysis of the development of average seat capacity at congested airports, in contrast to the situation at not yet congested airports, and to find out the reasons for airlines increasing the number of seats at congested airports, by means of a statistical model using variables including the degree of airport congestion and average flight distance.     

The costs of peak-load demand: An application to Gran Canaria airport

Many airports suffer from peak-load demand problems. To meet unconstrained demand at peak periods, they often invest in extra capacity that may be under used at other times. We use data from the airport in Gran Canaria to illustrate that costs associated with the peak-load problem are not only those related to the new investment. This paper provides a methodology for analyzing the costs arisen due to the peak-load demand, to explore alternative airport policies and to illustrate the problem of congestion at airport terminals. The results suggest that a situation in which airports differentiate charges by peak and off-peak days would be much desirable.     

Airport slot allocation: a time for change?

The increasing imbalance between airport capacity and traffic resulted in exceptional congestion and delays drawing the attention of aviation policy makers towards airport demand management for the allocation of scarce airport slots. Attempts to bring forward airport demand management measures in the form of airport slot allocation were not widely adopted and have not flourished in practice. This paper aims: (i) to apply a methodological framework for the selection of the most suitable slot allocation strategy for various types of airports, (ii) to explore potential impacts such that measures or strategies can bring about, and (iii) to assess the suitability of the existing airport pricing scheme and the potential implementation of a new policy regime aiming to bridge the gap between growing traffic and scarce airport capacity.     

Covid −19, the collapse in passenger demand and airport charges

This paper analyses the price responses of airports to a demand collapse, such as that prompted by Covid-19. In the crisis, airports need to achieve viability, in the short run through sufficient liquidity, and in the long run, by covering costs. From a public policy viewpoint, price increases in a crisis are argued to be undesirable, as they would further jeopardise the viability of airlines and tourism as well as the wider economic transport benefits such as connectivity. The institutional environment of airports differs from airport to airport; some are publicly owned, others are private but regulated, and others face competition. The price response of each (of 6) types of airport is considered, and how policy could respond to keep prices low in the crisis while ensuring longer term viability. Regulated airports could defer price increases until demand had recovered, if regulators insisted they do so. Publicly-owned airports could be directed by governments to keep charges low. Governments might also state that unregulated airports that raised charges could be made subject to price regulation in the future. Competitive airports would be unable to raise charges but this could jeopardise their viability. In this case and others where airports might need financial assistance, assistance could be made conditional on keeping charges low in the crisis.     

Intermodal integration in air transportation: status quo, motives and future developments

Soaring air traffic, increasing urban expansion and airports operating at full capacity are reasons that have caused a discussion about improvements in airport landside access systems. One approach to better match customer demands and address airport congestion is to facilitate the intermodal integration of airports. Building on a survey on intermodal passenger air transportation, we elaborate on the current and future situation at major airports. Our findings indicate a high modal concentration and dependence on individual access modes. However, while airport managers intend to reduce the share of these modes, they plan to increase that of high-occupancy airport access modes. We analyze the underlying motives that cause airports to extend their connections to surface infrastructure. In a case study, we assess an intermodal best practice solution for the integration of air and rail.     

Privatization,corporatization, ownership forms and their effects on the performance of the world's major airports

This paper focuses on measuring and comparing productive efficiency and profitability among airports owned and operated by government departments, 100% government-owned corporations, independent airport authorities, mixed enterprises with government majority ownership and mixed enterprises with private majority ownership. The analysis is based on a cross-sectional, time-series dataset (2001–2003) for the major Asia-Pacific, European and North American airports. There is strong evidence that airports with government majority ownership and those owned by multi-level of government are significantly less efficient than airports with a private majority ownership; there is no statistically significant evidence to suggest that airports owned and operated by US government branches, independent airport authorities in North America, or airports elsewhere operated by 100% government corporations have lower operating efficiency than airports with a private majority ownership; airports with a private majority ownership achieve significantly higher operating profit margins than other airports; whereas airports with government majority ownership or multi-level government ownership have the lowest operating profit margin; and generally, airports with a private majority ownership derive a much higher proportion of their total revenue from non-aviation services than any other category of airports while offering significantly lower aeronautical charges than airports in other ownership categories excluding US airports. The results suggest that private–public–partnership with minority private sector participation and multi-level governments’ ownership should be avoided, supporting the majority private sector ownership and operation of airports.     

Access mode choice for relocated airports: the new Athens International Airport

To estimate the capacity requirements for all access related facilities of a new airport and to set pricing or operational policies it is necessary to forecast the share of each transport mode that airport passengers use. The development of these forecasts cannot be based on mere transfer of experience from other airports, particularly in the modern era of wide regulatory reforms, liberalization of the aviation market and increasing airport competition. First access modal split at the existing airport is determined via passenger classification and discrete choice modeling. Both are conducted via a passenger survey study specifically designed for this purpose. The resulting models are then employed to forecast access modal splits for the relocated airport by proper adjustment of the attribute values. The method is applied to the new Athens International Airport.     

Airports’ role as logistics centers in humanitarian supply chains: A surge capacity management perspective

The purpose of this study is to investigate the key factors of airport logistics surge capacity and the relationships between these elements. The findings show that successful airport surge capacity management is closely related to prioritizing the flights and operational activities; considering the influx of local people to airports and local infrastructure capacity in the planning phase; developing suitable methods to encourage people to take part in surge operations; providing uninterrupted communication in and out of airport. In view of the above-stated findings this study suggests that airports can meet the surge demand through systematic capacity planning of the existing and additional human, supply, system and space elements by considering experienced or anticipated capacity shortages in disaster conditions.     

Policy issues and planning of UK regional airports

The principal motivation for this paper is to examine the policy issues for UK regional airports within the air transport system with particular reference to airport airline relationships. The geography of airline route networks is considered a key factor that determines location of the pressure for infrastructure development. Regional airports policy is considered in this context. The problems of the resultant concentration of air traffic has largely been ignored up until now and so this paper seeks highlight the issues this presents to policy makers. The paper reviews the changing regional airport ownership patterns and examines a range of implications. It then explores the policy implications for the future regulation and development of the air transport system. The authors contend that regulation and the planning system are the only two remaining policy levers for government to guide privately owned airlines, privately owned airports and commercialised airports towards national policy goals.     

The impact of airport capacity constraints on future growth in the US air transportation system

This paper simulates airline strategic decision making and its impact on passenger demand, flight delays and aircraft emissions. Passenger flows, aircraft operations, flight delays and aircraft emissions are simulated for 22 airports in the US, under three airport capacity scenarios. The simulation results indicate that most system-wide implications for operations and environmental impact seem to be manageable, but local impacts at congested hub airports may be significant. The response of the air transportation system to avoid airports with high delays could significantly impact passenger demand and air traffic for these and directly dependent airports. The simulations also suggest that frequency competition effects could maintain flight frequencies at high levels, preventing a significant shift toward larger aircraft, which would otherwise reduce the impact of the capacity constraints.     

Operational performance evaluation of international major airports: An application of data envelopment analysis

This paper uses data envelopment analysis to assess the operational performance of 20 major airports around the world. It is found that the form of ownership and the size of an airport are not apparently correlated with operational performance of airports. In contrast, the existence of a hub airport, the location of the airport, and the economic growth rate of the country in which the airport is located are all related to the operational performance of airports. The 20 airports are put into four groups according to their efficiency values.     

Designing the airport airside for the new large aircraft

Aircraft manufacturers are developing double decked aircraft known as new large aircraft (NLA) to cope with the growth in demand for air transportation. Because of the greater dimensions, the introduction will require changes in the airside configuration of practically all airports where they are to operate. Even for new airports, revised standards may be necessary to take into consideration the innovative technological features that will be present on those aircraft. This paper reviews the main issues related to the compatibility of the NLA with the airport airside and the related solutions that have been proposed.     

Future airport terminals: New technologies promise capacity gains

The changing dynamics of passenger processes in future airport terminals resulting from pressures from both the demand and supply side are analyzed in this paper. Short and long term (beyond 2020) developments are studied following technology advances and business plans of airlines and airports. Key technologies affecting the central passenger processing functions include identity management and biometrics, Near Field Communications, Big Data analytics and smartphone applications. A simulation model is developed and used to assess the impact of forthcoming changes on the airport's departure hall. Lisbon Portela airport is used as case study. It is shown that passenger process times at the check-in and security checkpoints are significantly reduced, due to the introduction of passenger facilitation processes, under a range of behavioral, technological and policy uncertainties. The most salient implication of these reductions is the quantified capacity gains in the building which question the need for terminal expansion.     

Privatisation and commercialisation: Changes in UK airport ownership patterns

This paper examines changes in airport ownership patterns with reference to UK municipal airports. The implications of commercialisation and privatisation are explored at a national level. General issues and impacts that may serve as a guide to policy makers worldwide are identified. The need for countries to have a strategic airports policy to guide development towards national economic and environmental goals is highlighted. The paper concludes that a uniform pattern of privatised airport ownership offers benefits from economic, policy and planning perspectives. © 1999 Elsevier Science Ltd. All rights reserved     

An assessment of the capacity and congestion levels at European airports

This paper examines the current capacity of the EU's airport infrastructure and the main factors determining that capacity. The nature and role of airport services are detailed. The determination of capacity is examined with discussion of the influence which air traffic control factors, demand characteristics, environmental conditions and engineering design will have on capacity. The methods used to assess delay are detailed along with extensive data sketching the current state of Europe's system of large airports and the extent of infrastructure congestion. The options available to policy makers to improve the management and organisation of capacity are set out and critically discussed.
