Icelandair adds St. Louis, its 16th U.S. city

Icelandair will launch nonstop flights between Keflavik International Airport (KEF) near Reykjavík and St. Louis Lambert International Airport (STL) starting May 14, 2027, The Points Guy reported Wednesday. Service will run through Oct. 24, 2027, with flights on Mondays, Wednesdays, Fridays and Sundays.

The airline will operate a Boeing 737 MAX 8 on the route, configured with 16 business-class recliner seats and 144 economy seats.

St. Louis becomes Icelandair's 16th U.S. gateway and its first new American destination added in 2027. According to Cirium schedule data cited by The Points Guy, Icelandair is flying 15% more seats to the U.S. this year than it did in 2019.

The new route strengthens Icelandair's partnership with Southwest Airlines, which is the busiest carrier at STL. Passengers on both airlines can use St. Louis as a transfer point for trips between the U.S. and Europe.

"St. Louis is an exciting addition, further strengthened by our growing partnership with Southwest Airlines, which will create convenient connections between destinations across North America, Iceland, and Europe," Tómas Ingason, Icelandair's chief commercial officer, said in a statement.

St. Louis already has two European carriers: British Airways and Lufthansa, both of which began flying to the Midwestern city after the pandemic. A previous attempt at the Reykjavík-St. Louis route was made by low-cost carrier WOW Air in 2018 and 2019 before that airline ceased operations.

Travelers booking Icelandair's new route can take advantage of the airline's free stopover program, which allows up to seven days in Iceland.
