Icelandair has announced plans to introduce a new route to Saint-Louis, Missouri, and to resume flights to Madrid during the summer of 2027. The airline also aims to strengthen its partnership with Southwest Airlines to provide more travel options across the United States. These developments are part of a broader strategy to expand Icelandair’s network and improve connectivity for passengers traveling between North America, Iceland, and Europe. Flights to Saint-Louis are expected to begin on May 14, 2027, and continue until October 24, with three to four weekly departures. The schedule will include Mondays, Wednesdays, Fridays, and Sundays, with some weeks offering more frequent service. Saint-Louis will not only be a new destination but also a transfer point, allowing travelers to connect to other U.S. destinations through Icelandair’s partnership with Southwest Airlines. This move is expected to improve access to Texas and surrounding states for passengers departing from Iceland. In Europe, Icelandair will restart flights to Madrid from April 9 to October 25, 2027. The service will include two to three weekly flights, with departures on Mondays, Wednesdays, and Fridays. Unlike the Saint-Louis route, the Madrid service will operate for a longer season, starting in early April and ending in late October. However, the exact number of flights per week may vary depending on the time of year, and passengers will need to check the detailed schedule for specifics. These new routes reflect different goals for Icelandair: reintroducing Madrid to its European network and adding Saint-Louis as a new American entry point with transfer options. The expansion is part of an interline agreement with Southwest Airlines, which allows passengers to book combined flights on a single ticket. This agreement will make Saint-Louis a key hub for connecting Southwest Airlines’ U.S. network with Icelandair’s European destinations. Details about luggage handling and transfer procedures will be available closer to the launch dates. Icelandair’s commercial director, Tómas Ingason, noted that these additions will enhance travel options as the airline prepares to celebrate its 90th anniversary in June 2027. With the introduction of Saint-Louis, Madrid, and expanded transfer opportunities through Southwest Airlines, the airline aims to offer more destinations and greater flexibility for travelers looking to extend their journeys beyond Icelandair’s direct routes.
