Old conflicts, new rivals? Airline competition in the European market

Christoph Franz of Lufthansa recently identified Ryanair, easyJet, Air Berlin and Emirates as the company’s main competitors – gone are the days when it could benchmark itself against BA or Air France-KLM! This paper probes behind the headlines to assess the extent to which different airlines are in competition, using evidence from the UK and mainland European markets. The issue of route versus network competition is addressed. Many regulators have put an emphasis on the former whereas the latter, although less obvious, can be more relevant. For example, BA and American will cease to compete between London and Dallas Fort Worth if their alliance obtains anti-trust immunity but 80% of the passengers on this route are connecting at one or both ends and hence arguably belong to different markets (e.g. London-San Francisco, Zurich-Dallas, Edinburgh-New Orleans) which may be highly contested. The remaining 20% of local traffic is actually insufficient to support a single point to point service in its own right. Estimates are made of the seat capacity major airlines are offering to the local market as distinct from feeding other routes. On a sector such as Manchester–Amsterdam, 60% of KLM’s passengers are transferring at Schiphol as against only 1% of bmibaby’s. Thus although KLM operates 5 flights and 630 seats per day against bmibaby’s 2 flights and 298 seats, in the point to point market bmibaby offers more seats than KLM. The growth of the Low Cost Carriers (LCCs) means that competition increasingly needs to be viewed on city pair markets (e.g. London-Rome) rather than airport pair markets (e.g. Heathrow-Fiumicino). As the stronger LCCs drive out weaker rivals and mainline carriers retrench to their major hubs, some markets now have fewer direct options than existed prior to the low cost boom. Timings and frequencies are considered, in particular the extent to which services are a true alternative especially for business travellers. LCCs typically offer lower frequencies and more unsociable timings (e.g. late evening arrivals at remote airports) as they are more focused on providing the cheapest service rather than the most convenient schedule. Interesting findings on ‘monopoly’ services are presented (including alliances) - certain airlines have many more of these than others. Lufthansa has a significant number of sectors to itself whereas at the other extreme British Airways has direct competition on almost every route in its network. Ryanair and flybe have a higher proportion of monopoly routes than easyJet or Air Berlin. In the domestic US market it has become apparent since deregulation that better financial returns can come from dominating a large number of smaller markets rather than being heavily exposed in the major markets - which are hotly fought over. Regional niches that appear too thin for Ryanair to serve (with its all 189 seat 737-800 fleet) are identified. Fare comparisons in contrasting markets provide some insights to marketing and pricing strategies. Data sources used include OAG (schedules and capacity), AEA (traditional European airlines traffic by region), the UK CAA (airport, airline and route traffic plus survey information of passenger types) and ICAO (international route traffic and capacity by carrier). It is concluded that airlines often have different competitors depending on the context but in surprisingly many cases there are actually few or no direct substitutes. The competitive process set in train by deregulation of European air services in the 1990s is leading back to one of natural monopolies and oblique alternatives. It is the names of the main participants that have changed however!

Considering the relationship between freight transport and urban form

There has been much discussion since the mid-1980s about the relationship between transport and urban form. However, all of this body of research has concerned itself with passenger transport (i.e. the movement of people). This report is intended as an initial investigation into the relationship between road freight transport and urban form. Important trends in road freight transport and logistics and the land use associated with these activities are discussed. Data about road freight transport activity by heavy goods vehicles (HGVs) in Britain that has been disaggregated from a UK government survey is analysed to investigate the nature of urban freight operations in sixteen selected urban areas. This includes analysis of the efficiency and transport intensity of these operations on journeys to, from and within each urban area. Scenarios concerning urban freight operations based on reductions in length of haul, and improvements in vehicle lading factors, vehicle carrying capacities and empty running are constructed in order to investigate the potential effect of such changes on the vehicle kilometres performed on journeys to, from and within the sixteen urban areas.

The challenge of managing airline delay costs

Estimates of airline delay costs as a function of delay magnitude are combined with fuel and (future) emissions charges to make cost-benefit trade-offs in the pre-departure and airborne phases. Hypothetical scenarios for the distribution of flow management slots are explored in terms of their cost and target-setting implications. The general superiority of passenger-centric metrics is of significance for delay measurement, although flight delays are still the only commonly-reported type of metric in both the US and Europe. There is a particular need for further research into reactionary (network) effects, especially with regard to passenger metrics and flow management delay.

Modelling the airline costs of delay propagation

Reactionary delays constitute nearly half of all delay minutes in Europe. A capped, multi-component model is presented for estimating reactionary delay costs, as a non-linear function of primary delay duration. Maximum Take-Off Weights, historically established as a charging mechanism, may be used to model delay costs. Current industry reporting on delay is flight-centric. Passenger-centric metrics are needed to better understand delay propagation. In ATM, it is important to take account of contrasting flight- and passenger-centric effects, caused by cancellations, for example. Costs to airlines and passenger disutility will both continue to be driven by delay relative to the original schedule.

ADR in aviation: European and national perspectives

The air transport sector generates the largest share of cross-border consumer complaints, as a proportion of complaints received by the ECC-Net. Since the foundation of the ECC-Net in 2005, air passenger claims have made up around one fifth of the total caseload most years. A pan-European framework of bodies that handle consumer to business disputes will be implemented through the consumer ADR directive.4 Taking these developments into consideration, the aviation industry is an interesting sector to study. This paper looks at dispute resolution for air passengers in the United Kingdom (UK) and Germany, as well as at European level.

Transverse Vibrations in Beams Supported by a Piece-Wise Homogeneous Visco- Elastic Foundation

Transversal vibrations induced by a load moving uniformly along an infinite beam resting on a piece-wise homogeneous visco-elastic foundation are studied. Special attention is paid to the additional vibrations, conventionally referred to as transition radiations, which arise as the point load traverses the place of foundation discontinuity. The governing equations of the problem are solved by the normalmode analysis. The solution is expressed in a form of infinite sum of orthogonal natural modes multiplied by the generalized coordinate of displacement. The natural frequencies are obtained numerically exploiting the concept of the global dynamic stiffness matrix. This ensures that the frequencies obtained are exact. The methodology has restrictions neither on velocity nor on damping. The approach looks simple, though, the numerical expression of the results is not straightforward. A general procedure for numerical implementation is presented and verified. To illustrate the utility of the methodology parametric optimization is presented and influence of the load mass is studied. The results obtained have direct application in analysis of railway track vibrations induced by high-speed trains when passing regions with significantly different foundation stiffness.

Avaliação do desempenho de ligações tubulares em estruturas de veículos pesados de passageiros por simulação numérica

Nesta Dissertação ir-se-á avaliar o desempenho de algumas ligações existentes nos veículos pesados de passageiros, através do Regulamento Eurocódigo 3. Nos últimos anos ocorreram diversos acidentes envolvendo este tipos de veículos, em que os mesmos causaram vítimas mortais e feridos graves. Serão testadas por simulação numérica algumas ligações pertencentes a elementos constituintes da superestrutura, em que esta é normalmente afectada com a ocorrência de acidentes. Assim sendo, o estudo de nós de ligação tem uma importância fulcral para que uma superestrutura suporte situações extremas e que resista a solicitações externas aplicadas. Iniciou-se esta Dissertação com o estudo da sinistralidade e de acidentes que envolvem veículos pesados de passageiros. No capítulo 2 abordou-se um programa que promove simulações numéricas de acidentes e estudo do comportamento dos passageiros em caso de acidente, sendo referido o Regulamento que homologa os veículos pesados de passageiros e os seus principais métodos. Abordaram-se os principais constituintes da estrutura de um veículo pesado de passageiros. No capítulo 3, é referido o Eurocódigo 3 em termos do estudo das ligações tubulares usadas neste tipo de veículos. No capítulo 4, fez-se o estudo e selecção de elementos a utilizar para a simulação numérica de casos preconizados pelo Eurocódigo 3 e estudaram-se três tipos de ligações que são usadas na construção da superestrutura deste tipo de veículos, tendo-se retirado conclusões deste estudo.

Avaliação do comportamento de uma ponte metálica centenária sujeita à ação de tráfego ferroviário ligeiro

A presente dissertação tem como objetivo principal a análise numérica do comportamento dinâmico de uma ponte ferroviária, sob ação de tráfego ligeiro ferroviário. Neste contexto são apresentados alguns fundamentos teóricos a ter em conta nestes domínios, visando uma melhor compreensão dos fenómenos existentes no comportamento dinâmico de pontes ferroviárias quando sujeitas ao tráfego. O caso de estudo teve como foco a ponte Luiz I, uma ponte metálica situada sobre o rio Douro, que liga as cidades do Porto e Vila Nova de Gaia, sob ação de tráfego ligeiro ferroviário no seu tabuleiro superior para a condição anterior aos trabalhos de reabilitação e reforço realizados entre 2004 e 2005. Para o efeito foi desenvolvido um modelo numérico de elementos finitos da ponte realizado com recurso ao programa ANSYS, assim como um modelo numérico do veículo do Metro de Lisboa. Com base nestes modelos foram obtidos os parâmetros modais, nomeadamente as frequências naturais e os modos de vibração de toda a estrutura e do veículo. O estudo do comportamento dinâmico da ponte foi realizado por intermédio de uma metodologia de cargas móveis e de interação veículo-estrutura, através da ferramenta computacional Train-Bridge Interaction (TBI). As análises dinâmicas foram efetuadas para a passagem dos veículos de passageiros das redes de Metros do Porto e Lisboa. Nestas análises é estudada a resposta da estrutura em função da variabilidade ao nível da secção transversal, dependência do tramo, influência do veículo, da sua velocidade de circulação e impacto das frequências de vibração estimadas pelo modelo numérico.
