| We had booked the Wowair stopover Detroit to Barcelona via Keflavik and just shy of 2 weeks prior to our vacation (family of 5), we received a text and email from Wowair saying they had cancelled our BCN stopover. Because we had already scheduled time off work and school and hotels, cars, meeting others in Barcelona, we were forced to buy connections on Air France. WOW said they could get us as Paris so we had to purchase 5 round air tickets from CDG to BCN, lost 2 days of our vacation, lost a night in a hotel in BCN, had to pay for a hotel at CDG, spent almost 2 full days dealing with connections, layovers (extra costs for food, car etc) Then several days before our DTW to KEF flight, WOW air changed our airplane and scattered us all over the airplane (kids in middle seats in back etc). We were one of the first to book on the flight (Was empty at time) and had paid to purchase upgraded seats together/seats together. Wow did not honor seat assignments. spent close to 2 days on phone / email / twitter support with Wowair and AirFrance and hotels/car rental scheduling, rescheduling, getting seat assignments, seeking compensation. Wow cites an EU regulation that if cancel 2 weeks before, will offer no compensation; they slipped in just before 2 week window with cancelled flights. The staff was very nice but the company is just horrible. We were out approximately $2000 all in and no compensation or accommodation from company. Very sad because this was a long planned family trip that we had saved for and planned for a long time. The day we were flying, the company was offering "free flights to people with the last name Valentine". Very gimmicky and not taking care of their paying customers. Lastly, truly the most uncomfortable flight we have ever been on. It is a discount airline but so this is to be expected (though not at all discount when they screw you and cancel your flight). The economy / no upgrade seats are the most uncomfortable you could imagine, people were very miserable. Many families, could not move around at all. The first three rows were very large, like the people could do a pike/legs straight out. Makes no sense to give the upgraded seats too much room while the other 30 rows really suffered. The flights were packed and a lot of unhappy people. They charge for even water so the by the time you pay for water, food, definitely consider an upgrade, charges for luggage and if you are really unlucky - cancellation fees - you could fly first class with a reputable airline. Iceland is lovely but fly Delta or United or partners or anyone but Wowair. I read many many complaints on the internet etc. that they did this same behavior to many many other people. Company really does not deserve your hard earned vacation dollars. I would urge you to fly a more reliable airline.
