Starting in late October, travelers will be able to fly from the Swedish capital to the eastern European capitals of Prague in the Czech Republic and Warsaw, Poland.
New routes will also serve the Polish cities of Krakow and Lodz.
The low-price carrier sees the expansion, which also includes increased capacity on existing routes from Stockholm to Berlin, Milan, Riga, and Eindhoven, as a direct challenge to national carrier Scandinavian Airlines (SAS).
“Swedish passengers have grown tired of SAS’s unreasonably high prices and unnecessary fuel surcharges,” said Ryanair’s marketing director Dara Brady in a statement.
“With these new routes, Ryanair will carry 2.5 million passengers annually to and from Stockholm Skavsta for a fraction of SAS’s higher prices.”
SAS has struggled to manage the duel challenges of increasing operation costs and tighter competition in the European airline market, with its shares having lost around 80 percent of their value in the last year.
In May, the company introduced a €10 ($15.54) fuel surcharge to domestic ticket prices and a €15 charge for flights in the rest of Europe in an effort to offset the costs of rising fuel prices.
