Icelandic budget carrier, WOW Air, is expanding their service out of the Baltimore/Washington International Thurgood Marshall Airport (BWI), and they’re celebrating with $99 flights.

The airline is offering a limited number of $99 one-way tickets from BWI to Iceland’s Keflavik International Airport as it prepares to nearly double down on its current flight offerings between the two locations.

Currently, WOW Air offers daily roundtrip flights between the two airports, and will be increasing that to two daily flights offered every Tuesday, Thursday, Saturday, and Sunday between May 18 and September 16 of 2018.

This will allow the airline to take its total flight capacity between the two destinations up by 45 percent in comparison to this year, according to WOW Air representatives, with a total of eleven flights available each week.

Besides the ultra cheap flights to Iceland, the airline is also offering flights to London, Amsterdam, Paris, Dublin, Berlin, and Frankfurt starting at $149 one-way.

Since WOW AIR also has a free stopover program in Iceland on return flights between North American and Europe, you can get a chance to explore the country’s offerings free of charge on your way home.

Since launching in November of 2011, the low-cost carrier has been offering ultra cheap flights throughout Europe, with fares from the U.S. dipping as low as just $69 one-way.

In total, Wow Air now connects 38 destinations across the U.S. and Europe, and is even discussing branching out to soon offer low fares to Asia.

Passengers will want to note with the low fares, however, that the airline is a budget carrier so it charges for amenities ranging from in-flight entertainment to meals and beverages.
