WOW Air announced on Tuesday the addition of four new routes from cities across the Midwest — and their famous $99 one-way flights to Iceland to celebrate.

The fast-growing budget carrier is now servicing Cleveland, Cincinnati, Detroit, and St. Louis, increasing its U.S. presence from eight cities to twelve.

“We like the region,” WOW Air founder and CEO Skúli Mogensen told USA Today. “We think there’s opportunity there. We think [the Midwest] is under-served.”

Even if travelers based in these cities hadn’t originally been planning on taking a trip to Europe, they might be inspired to do so by the price. Travelers can continue on from Reykjavik to Berlin, Dublin, Frankfurt, London, Paris, with round-trip flights costing as little as $248. Additional connections include Copenhagen and Amsterdam.

Service from Detroit begins on April 26, with the remaining routes launching in early and mid-May.

According to Thrifty Traveler, the best fares can be found between April and June, and between August and October of 2018, with availability varying with each city.
