Connecting flights to WOW’s other European locations will begin at $149.99.When asked if there was enough demand in the Midwest for the new non-stop flights to Iceland, WOW Air founder and CEO Skuli Mogensen said yes. “With those kind of prices, we have seen in other markets that we enter that we have stimulated the market significantly.”“Our unique opportunity is to use Iceland as a hub. We can then distribute to our main destinations in Europe, be it London, Paris, Amsterdam, Frankfurt, Berlin, Copenhagen, etc.,” Mogensen said. “That’s really the key. Instead of having a single point-to-point flight, we actually give you a very affordable flight to multiple destinations.”In reaction to this news, major airline stocks fell.
