WOW Air via ShermansTravel offers WOW Air 1-Way Flights to Scandinavia and Europe from select cities in the U.S. on sale with prices starting from $99. (On the ShermansTravel landing page, click on "WOWAir.com" in the main paragraph to see this sale.) That's tied with last week's mention as the lowest price we could find for departure in September 2017 by up to $100. This price is valid on flights departing from Miami, FL, (MIA) with arrival in Reykjavik, Iceland, (KEF) on September 19, 2017. Note that this airline is a "non-bundle" airline, so seat reservation and luggage costs are additional. Other routes include flights to London, England (LGW); Amsterdam, Netherlands (AMS); and Paris, France, (CDG). This travel deal applies to flights on select dates from October 1, 2016 through October 31, 2017.
