Detroit Metro Airport will welcome a new airline in 2018: Low-cost transatlantic carrier WOW Air.

WOW Air, based in Iceland, will begin service out of Detroit on April 26, 2018, with one-way trips to Iceland for $99, airport officials announced this morning.

The airline announced service from Detroit, St. Louis, Cleveland and Cincinnati, an expansion that will give it a total of 12 U.S. destinations.

The three other routes will launch in May.

Tickets officially went on sale today.

As of this morning, Wow Air's website was offering one-way flights from Detroit to Reykjavik, the capital city of Iceland, for $99.

“We’re very excited about these cities,” WOW Air founder and CEO Skúli Mogensen said to USA TODAY’s Today in the Sky blog.

Mogensen predicted the carrier’s budget fares will help boost demand, catering to pent-up demand for cheap trans-Atlantic flights.

“With those kind of prices, we have seen in other markets that we enter that we have stimulated the market significantly,” he said.

In other words, if fares drop below a certain threshold, people who otherwise would not consider traveling to Europe will do so because of the inexpensive fares.

On all four routes, WOW will fly four flights a week to its hub at the Keflavik airport near Reykjavik on Airbus A321 aircraft. Connecting itineraries will be available to more than two dozen destinations in Europe.
