The airport has been granted the permission by environmental regulators, the airport’s Spanish owner Abertis Infraestructuras announced on Thursday.
Skavsta’s expansion would take it past Gothenburg Landvetter and Malmö Sturup to become Sweden’s second biggest airport, based on current passenger numbers. Only Stockholm Arlanda Airport currently carries more passengers, with over 16 million people travelling through the airport annually.
“This fits very well into our master-plan for the airport,” said Dot Gade Kulovuori, managing director of the airport, to The Local.
Under the terms of the permit, the airport has undertaken to investigate flight paths from the perspective of emissions, noise and safety considerations.
The airport, 100 kilometres south of the Swedish capital, is popular with low cost airlines and serves as Ryanair’s main Stockholm base. The Irish airline is currently in negotiations to base a further two planes there.
Winter charter routes to Bulgaria, Greece, Turkey and Majorca were added last year, with services to Thailand and Tunis due to start this year.
Plans for a new rail link are awaiting government approval. The link, part of a new rail service for eastern Sweden, could be finished as early as 2013. A rail line would reduce travelling times from the capital to less than 40 minutes, compared to the current 80 minutes by bus.
