Icelandair will start nonstop flights between St. Louis Lambert International Airport (STL) and Reykjavik on May 14, 2027. The seasonal route runs up to four times a week through October 24, and it makes St. Louis Icelandair's 16th U.S. destination.
The schedule is set, so this is a date you can plan a trip around now. It's also a comeback: St. Louis had a nonstop to Iceland before, on WOW Air, which went out of business in 2019.
What Icelandair Announced
- Route: St. Louis (STL) to Reykjavik, nonstop
- Season: May 14 to October 24, 2027
- Frequency: up to four flights a week, on Mondays, Wednesdays, Fridays and Sundays
- Aircraft: Boeing 737 MAX 8
Icelandair is also widening its partnership with Southwest Airlines, the largest carrier at Lambert. The airlines say customers will be able to connect from cities across North America through St. Louis to Iceland and on to Icelandair's destinations in Europe.
Where It Fits in St. Louis's Europe Options
Lambert already has nonstop flights to Europe on British Airways to London and Lufthansa to Frankfurt. Icelandair adds Reykjavik to that list.
That matters most for travelers who want Iceland itself. The route brings back nonstop service between St. Louis and Iceland, so from May 14, 2027, you can fly there without a connection.
If you've been weighing Iceland against a trip to London or Germany, the comparison changes once all three are nonstop from home. The deciding questions become which days each flight runs, what each costs on your dates, and how you plan to pay.
What You Should Do
If Iceland is on your list for summer 2027, start with the calendar. The flights run on Mondays, Wednesdays, Fridays and Sundays, so pick travel dates that line up with them in both directions, and keep the trip between May 14 and October 24.
Next, price the trip both ways: in cash and, if you hold points that can cover it, in points. Compare the two on the same dates before you commit.

The Bottom Line
From May 14, 2027, you can fly from St. Louis to Reykjavik without a connection, up to four days a week through October 24. If you're planning Iceland for next summer, check those days first and build the rest of the trip around them.
