Icelandair announced a new route from Keflavík to St. Louis on 7 October 2026. It starts on 14 May 2027 and is flown by Boeing 737 MAX 8s, according to the schedule listing on AeroRoutes and a report in Iceland Review. Iceland Review describes St. Louis as Icelandair's 16th US destination.

The schedule

AeroRoutes lists three flights a week from 14 May 2027, rising to four a week between 31 May and 12 September 2027. Iceland Review says the service is planned to run until 24 October 2027.

The timings in the AeroRoutes listing are local times:

  • FI835 leaves Keflavík at 17:15 and arrives in St. Louis at 19:30.
  • FI834 leaves St. Louis at 20:45 and arrives in Keflavík at 08:20 the next morning.

Iceland keeps UTC all year, and in May St. Louis will be on Central Daylight Time, five hours behind. By my arithmetic from those times, that makes the westbound flight about seven hours and fifteen minutes, and the return about six hours and thirty-five minutes. Those two figures are my sums, not the airline's.

Why the type matters

The 737 MAX 8 is a single-aisle jet, and on those published times the route is a little over seven hours long: across the North Atlantic and into the middle of the United States. It is a long sector for the type. Icelandair's MAX 8s already fly out of Keflavík to European cities, which is where I have seen them.

On my screen

The BBBRadar desk unit shows type, registration, route where one is filed, callsign and altitude. On 27 September 2026 it showed an Icelandair Boeing 737 MAX 8, TF-ICG, as ICE546, Keflavík to Paris Charles de Gaulle, at 35,000 feet. On 6 October it showed a second, TF-ICN, on the same ICE546 flight, at 37,000 feet.

That is the same type and the same airline that will fly the new route, caught on a different one. The screen does not show a St. Louis flight, because there isn't one yet.

What I have not confirmed

I could not find an Icelandair release, so the route details come from secondary reports. St. Louis Public Radio, which also covered the announcement on 7 October, gives the same start date but says "four weekly" and does not name the aircraft. That fits the AeroRoutes listing, where four a week is the summer peak and three a week is the pattern either side of it.
