St. Louis has long served as a key hub for travelers across the American Midwest. Icelandair’s decision to add direct service from Keflavik International Airport near Reykjavík marks a notable expansion for the airline and opens a fresh path for passengers in the heartland. The new route begins May 14, 2027, and runs through October 24 of that year. ([1])
A Strategic Addition for the Carrier
Icelandair has steadily grown its presence across the United States in recent years. The St. Louis route becomes the airline’s 16th gateway on this side of the Atlantic and its first new U.S. destination announced for 2027. Schedule data indicate the carrier plans to offer 15 percent more seats to American cities this year than it did before the pandemic.
The flights will operate three to four times each week on Mondays, Wednesdays, Fridays, and Sundays. This measured frequency aligns with seasonal demand while giving travelers reliable options for planning ahead. The service positions St. Louis as a convenient entry point for journeys that continue onward to Iceland and then across Europe.
Strengthened Ties With Southwest Airlines
Southwest Airlines maintains a strong presence at St. Louis Lambert International Airport, where it ranks as the busiest carrier. The new Icelandair route builds on an existing partnership between the two airlines and creates additional opportunities for seamless connections. Passengers can link domestic Southwest flights with Icelandair service to reach destinations in Iceland and beyond.
Tómas Ingason, Icelandair’s chief commercial officer, noted that the addition is further strengthened by the growing partnership with Southwest. The collaboration is expected to support convenient transfers between points across North America, Iceland, and Europe. For travelers based in the Midwest, this development reduces the need for longer connections through coastal gateways.
Context Among European Carriers at STL
St. Louis already welcomes service from two other European airlines. British Airways and Lufthansa both launched flights to the city in the years after the pandemic. Icelandair becomes the third carrier offering transatlantic options from the airport.
An earlier attempt at the Keflavik route came from the now-defunct WOW Air, which operated briefly in 2018 and 2019. The new Icelandair service arrives with a more established network and a clear emphasis on connections through its home base. Travelers can also take advantage of the airline’s free stopover program, allowing up to a seven-day stay in Iceland without additional airfare.
What This Means for Midwest Travelers
The route offers a practical new option for those who prefer to depart from a central U.S. city rather than traveling first to larger coastal airports. It supports both leisure trips focused on Iceland’s landscapes and onward journeys to European destinations. The seasonal window from mid-May through late October captures the warmer months when demand for northern travel tends to rise.
With the announcement now in place, travelers and travel planners have time to consider how the service fits into future itineraries. Icelandair’s expansion reflects steady growth in demand for routes that link smaller U.S. cities with European gateways. For St. Louis, the addition reinforces its role as a growing international access point in the Midwest.
