The notion of public interest is not always clear; hence and despite the illusionary objectivity offered by purely technical approaches, the treatment of corporate rivalry and competition issues is context dependent. To address any clashes of interests between origin and destination competition authorities, an effort should be made to move beyond a zero-sum game logic and closer to a win-win way of thinking. Origin authorities should understand that the sustainable operation of destination providers in the longer term is a prerequisite for tourist satisfaction and the achievement of consumer welfare. Similarly, destination competition authorities should understand that a “national champion” mentality and the acceptance of restrictive practices by local oligopolists in the context of a level play with “foreigners” may subsequently harm and impede the development of domestic tourism. Corporate rivalry should be encouraged; however, co-ordination success is also needed: co-opetition, therefore, may be the way forward.
