WOW Air, the Icelandic discounter known for its $99 one-way fares to Europe, announced Pittsburgh as its latest U.S. destination.

WOW said Monday morning that it will begin flying from Pittsburgh on June 16, operating four weekly flights to its hub near Reykjavik. WOW offers connections via Reykjavik to nearly two dozen European destinations, including Amsterdam, Berlin, London, Milan and Paris.

"Pittsburgh is certainly a destination on the rise and one that will appeal to a wide range of European travelers looking to discover somewhere different, so we’re thrilled to add the destination to our route list," WOW founder and CEO Skúli Mogensen said in a statement.

As it typically does when announcing new cities, WOW rolled out sale fares of $99 one-way to Iceland ($129 one-way on the return) and $149 to connecting destinations elsewhere in Europe. A quick search of the carrier's website on Monday morning showed the $99 fares were available, though the availability of those fares was somewhat limited.

And while WOW's base fares are often sold at rock-bottom prices, customers should know they'll pay a fee for nearly everything beyond a guaranteed seat somewhere on the plane. Part of a new breed of "ultra low cost carriers" that are expanding both in the USA and around the world, WOW charges a fee for everything from seat assignments to carry-on bags.

WOW will use 220-seat Airbus A321 narrowbody jets on the route. WOW flies those aircraft on several of its other nonstop routes from Iceland to the U.S. East Coast, including Baltimore/Washington and Boston

The announcement highlights WOW’s continued rapid expansion in North America; the airline has now announced service to seven U.S. airports and two in Canada.
