Corvera Murcia Airport has made steady progress since officially opening on 15 January and taking over from San Javier as the main civilian airport in the Murcia region.
As the first year draws to a close, routes continue to be added to the airport’s seasonal schedules, and officials report that their objectives are being met, albeit gradually.
Regional Operating Fee
Spanish national airport authority Aena will have to start paying the Murcia regional government an operating fee, after reaching a total of one million passengers passing through the Corvera terminal. This is the threshold at which the initial fee takes effect: €0.84 per passenger, for a total of €840,000.
Corvera Murcia is the only airport in Spain that Aena operates as a franchisee. According to franchise general manager, Mariano Menor, in an interview with La Verdad, Corvera Murcia Airport’s passenger traffic is around 10 per cent below that registered at San Javier in 2018, but 10 per cent above initiual forecasts when the Corvera contract was drawn up.
