LATEST MATERIAL CHANGE
What changed?
Icelandair has announced a new nonstop summer route from its Keflavik hub to St. Louis Lambert International Airport, slated to launch in May 2027. The service will be the airline’s 16th U. S. destination and marks a notable expansion of its partnership with Southwest Airlines, which will now cover the St. Louis market. The move is positioned to strengthen Icelandair’s business case by tapping a new U. S. gateway while also reflecting Southwest’s growing interest in connecting to Iceland. For travelers, the route offers a direct link between the Midwest and Iceland’s capital, potentially easing transatlantic travel and opening new code‑share opportunities.
Why it matters
The new St. Louis‑Reykjavik flight broadens Icelandair’s U.S. network and deepens ties with Southwest, offering travelers a new direct route and signaling strategic growth for both carriers.
