The Role of Secondary Airports for Today's Low-Cost Carrier Business Models: The European Case

One of the core characteristics of Low-Cost Carriers (LCCs) is their use of secondary and regional airports. However, nothing is fixed as the market constantly evolves and carriers modify their strategies in order to achieve growth. This paper uses the examples of Ryanair, easyJet and Norwegian to show how changes to LCC business models are affecting secondary airports across Europe. Using a content analysis, this paper first describes how airport choice factors for LCCs have evolved over the last 10 years. This is followed by a data analysis of historical and current airline network capacity to identify how LCC traffic at secondary airports is developing. The paper finds that cost, demand and efficiency are still the most important criteria for LCCs when choosing an airport to operate from. However, it also identifies that LCCs have become more interested in serving business passengers, which is why they are increasingly using primary airports (accounting for 58% of their recent capacity growth). Through the use of a selection of case airports it is finally concluded that the evolution of LCCs increases competition between primary and secondary gateways. In most cases, secondary airports are losing a significant amount of LCC traffic and only sustain flights to less important destinations. This research puts into question the future importance of secondary airports for LCCs. As not all airports have been impacted by the hybridisation of LCCs to the same extent, the results are not equally applicable to the whole European airport industry

Signatures of Quark-Gluon-Plasma formation in high energy heavy-ion collisions: A critical review

A critical review on signatures of Quark-Gluon-Plasma formation is given and the current (1998) experimental status is discussed. After giving an introduction to the properties of QCD matter in both, equilibrium- and non-equilibrium theories, we focus on observables which may yield experimental evidence for QGP formation. For each individual observable the discussion is divided into three sections: first the connection between the respective observable and QGP formation in terms of the underlying theoretical concepts is given, then the relevant experimental results are reviewed and finally the current status concerning the interpretation of both, theory and experiment, is discussed. A comprehensive summary including an outlook towards RHIC is given in the final section.Comment: Topical review, submitted to Journal of Physics G: 68 pages, including 39 figures (revised version: only minor modifications, some references added
