Icelandair adds Madrid and St Louis routes for summer 2027

Original announcement · 8 October 2026 at 10:18 UTC

What Icelandair announced

Icelandair Group announced on Thursday 8 October that Madrid will return to the airline network and St Louis will become a new destination for summer 2027. Both services connect through Keflavík Airport.

The Madrid service is due to operate from 9 April through 25 October 2027. The airline says there will be two or three flights each week, scheduled on Mondays, Wednesdays and Fridays.

The St Louis service is due to operate from 14 May through 24 October 2027. Icelandair lists three or four flights each week, scheduled on Mondays, Wednesdays, Fridays and Sundays.

Who may find the routes useful

The Madrid return gives travellers in Spain another direct seasonal link with Iceland. The St Louis route creates a new direct option from the central United States. These dates may help visitors planning an Iceland trip well ahead of summer 2027, while Iceland residents gain two more seasonal departure choices.

Icelandair also says its expanded partnership with Southwest Airlines will offer onward connections through St Louis, particularly for travellers from Texas and nearby states. Check the actual itinerary before relying on a connection because the announcement does not set out every available city pair or connection time.

What travellers should do next

Updated 20 October 2026. In a separate announcement on 15 October, Icelandair said its Southwest partnership will include loyalty benefits from spring 2027. Saga Club members will be able to earn Saga Points and Tier Credits on Southwest flights. Rapid Rewards members will be able to earn and redeem points for Icelandair travel. This is a future benefit, not a service confirmed for today.

For visitors planning a connecting trip through St Louis, our practical advice is to check the programme rules and eligible itinerary when these benefits launch. Do not assume a booking made now already qualifies or that the announcement guarantees reward seats.

Use the official Icelandair flight schedule to check the exact date you want to travel. The announced weekly frequencies vary within each season, so a listed operating day should not be treated as a guarantee for every week.

Confirm the full itinerary, fare terms, baggage rules and connection details before paying. If Iceland is your destination rather than a connection, remember that international services use Keflavík Airport. Our Reykjavík guide can help with city planning after arrival, while the airline schedule remains the source for flight dates.

Why this is a planning announcement

The new routes are for summer 2027, not the current season. Schedules can change before travel, and this article does not confirm seat availability or a particular fare. Recheck the airline timetable and your own booking closer to departure.
