Competition in the Spanish domestic airline sector Market deregulation, switching costs and route cost behaviour

Purpose The purpose of this paper is to analyse the role of switching costs (SwCs) on established firm cost behaviour towards a competitive entry in the Spanish domestic airline market, taking into account the entrant profile and airport capacity restrictions. Design/methodology/approach The dynamic model is based on information of 193 Spanish domestic routes in which incumbents react to entrants (quarterly data during 10 years, 620 reactions are analysed). The balanced panel used is constructed by setting up a multiple-source database based on accounting and industrial engineering procedures. Findings Results show that both entrant profile and regulatory constraints conditions incumbent cost reaction (CR) to entry at the route-level. Regression models show that the relationship between SwCs and incumbent reaction is moderated by the entrant profile and the regulatory conditions of the market. Originality/value This study complements current literature related to incumbent CR to entry in the airline industry since it analyses the specific reaction performed by a carrier at the route-level. Moreover, it analyses the whole set of routes in the Spanish domestic market rather than a selection of it. It also explicitly includes three alternative measures of SwCs that can influence such incumbent reaction.
