Icelandair will start flying from Reykjavik to St Louis in 2027, adding a new US Midwest point to its transatlantic network.

The announcement, reported by Business Travel News Europe, extends a route map that has long relied on linking mid-sized North American cities to Europe through the carrier's Keflavik hub. For Icelandair, the St Louis service fits a distribution model in which secondary US markets feed European traffic via short connections in Iceland.

What does the new route change?

The 2027 start date gives sellers of travel a long lead time. Corporate travel buyers and leisure distributors in the St Louis catchment area gain a direct transatlantic option without routing through Chicago, Minneapolis or the East Coast hubs that currently serve Midwest-originating Europe traffic.

Icelandair has not yet published schedule details for the service. Frequency, aircraft type and an exact launch date within 2027 remain unconfirmed, so distributors should treat the route as announced rather than bookable.

Why does a Midwest gateway matter for sellers?

Icelandair's network strategy concentrates on city pairs that larger alliance carriers serve only with connections. Each new US gateway widens the pool of travellers who can reach Icelandair's European destinations — including London, Paris, Amsterdam and the Nordic capitals — on a single connection through Reykjavik.

For St Louis, the arrival of a transatlantic carrier typically shifts share from connecting itineraries on US majors and their joint-venture partners to a new nonstop product. The size of that shift will depend on the frequency Icelandair commits and the fares it files when the route opens for sale.

What should trade buyers watch next?

Three markers will define the route's commercial weight once details land:

• Launch date and frequency, which determine whether the service works for both leisure and corporate itineraries
• Aircraft and capacity, which signal how much connecting traffic Icelandair expects to flow over Keflavik
• Distribution terms, including GDS participation and agency commission levels at the point of sale

Until Icelandair files the schedule and opens bookings, the St Louis route is a network plan, not revenue. Sellers with Midwest clients should track the carrier's sales announcements through 2026 for the terms that will decide how the new capacity reaches the market.
