WOW is an Icelandic ultra-low-cost airline with their main hub in Reykjavik (KEF). WOW is in the process of being acquired by Indigo Partners (Frontier Airlines and Volaris). WOW was on the edge of insolvency when the deal occurred, so it will be interesting to see WOW after the deal closes.
Summary: I have never flown WOW, but my impression from reading about them is to stay away unless there is a really amazing deal. The fees are very high and the service is subpar. Also, if you follow our Flight Deals, you can likely find a better deal with a major airline when you factor in all of the fees.
