Ticket price.

Everything else. They book these flights too choose together. I almost think it's on purpose to trap people in Iceland for a day. We missed our connecting flight to Frankfurt by ten minutes, weren't told until we landed and were forced to stay in an awful hotel with mall vouchers that were barely edible. They would not entertain trying to get anyone on anther flight that day. Horrible and unapologetic customer service at the main wow airline desk.

NOTHING.

Cheap flight sounds great...except it’s not actually cheap. Once you add on charges for baggage, seats, water on board, etc., it’s about the price of a standard ticket on a quality airline. (Plus they didn’t actually reserve the seats I paid $20 for, even though I have the receipt). Amenities on board are atrocious. No Wifi, no in flight entertainment (except an iPad you can pay $25 for that features 10 movies from 1992), no USB ports...you even have to pay for water!!! My flight was delayed twice in one week causing me to miss my connecting flights both to my destination and back home by 5 minutes. Because they are not a member of an airline alliance, my only options were to wait until the next day and stay in a shared hotel room or rebook on another airline for $600 which they couldn’t guarantee I would be reimbursed for. The general apathy shown by the staff and lack of communication is abhorrent. The least they could do is apologize and help direct me to somewhere I could find more information. They were positively clueless! Spend a little extra and book on a respectable airline that values their customers...and maybe you won’t be out $1200 (in addition to the cost of the “cheap” tickets) like I am!!

Oh my god, I felt like a sardine. They developed their passenger seating scheme by carefully studying Iraqi prison torture manuals, I think. I didn't die but that outcome was surprising to me.

Flight way delayed 3 hours. Staff gave no information and wouldn't help rebook us onto other flights. They gave us food vouchers 2 minutes before we finally boarded, so we couldn't use them. The food on the plane had spoiled so we were all starving on the flight, and we all missed our connections. Horrible experience and wouldn't fly with KLM again.

Flight was very late. Reason given was a mechanical issue but last minute boarding was people whose flight out of Gatwick was cancelled and they were bussed to Heathrow so I suspect that was the real cause for the delay or at least a part of it

The ground crew was very curt and non helpful. Apparently there was a rule that laptops had to be in the checked baggage. The ground crew could have been more courteous with passengers for whom this was a great inconvenience. In my specific case, the person checking me in labelled my bad "Long Stay" instead of "Priority" because they misread the instructions on the computer. The person would not listen to me and would not re-check his potential error....I fly British Airways all the time and that did not seem to make a difference in his demeanor

Boarding was elated for two hours due to a problem with the air conditioning. We sat on the tarmac another hour before take off. The seats are uncomfortable, especially when sitting for nine hours.

Excellent 9.3

I loved the timeliness of the food service, and the options available for beverage service. The selection of movies and music available on the TV screen in the seat back was great, and allowed the time on the long plane ride to pass a little faster. The captain was extremely informative, about our flight path, the wind conditions, weather at our destination, etc. I particularly enjoyed the information he provided, because on some flights, you rarely hear from the person flying the plane.

The boarding process was interesting: those that needed assistance and business class 1st (understood), but then front of the plane, back of the plane, and finally the middle. I don't feel this made things go any faster - we still waited in line for quite some time in the jetway. I don't understand having front, back, and middle. Just let all economy get in line, or do something efficient like load the window seats first, the aisle, and for the seats in the middle of the plane, have the middle seats load 1st, and then the aisle seats. Seats got uncomfortable during the flight. Also, the person in front of me reclined ALL the way, so the top of her seat was only a few inches in my face. Most flights I have been on don't allow the seats to recline that far. I could barely get out of my seat to get up and go to the bathroom.

First time traveling with WOW and it was okay. Price was decent, a little better than Spirit, but the same with paying additional for everything so it's not really saving. Overall, great flight the pilots did a great job getting me to my destination (there and back) safely and with time to spare.

For a 9 hour flight they should accommodate their passengers with free beverages at least. The seats were very uncomfortable. Flight attendance were polite but very hard to get a hold of, they talk too much among each other, like HELLO you're working get it together! My flight was delay returning back to my original destination and no communication was received until a staff member showed up almost 2 hours late.

We arrived minutes earlier.

The cabin lights after dinner were supposed to go off so people could sleep. The lights were going on and off uncontrollably the last few hours of the flight. Flight attendant said the plane had issues with the "control panel because it was an old plane". The worst part was when a female flight attendant wouldn't move her feet over a few inches while sitting in her chair, so that I (a pregnant woman) could use the closest bathroom to my seat in the back cabin. I had to ask her twice and both times she confirmed "She was on her break and would not move her feet" so that I could use the bathroom. Also note, the seatbelt sign was off but that wasn't even her excuse. The bathrooms were dirty and the toilet seats need to be replaced to be asked to sit on those is degrading!

Crew was friendly. Not over the top friendly, but sufficiently doing their job to make the flight safe and pleasant.

The reclining function on several seats were broken. There were no ports to charge electronics while onboard. Very skimpy on giving out water. Had to ask several time for water as they would only give one itty bitty glass of water at a time. For an international flight this is unacceptable.

It was awesome how the windows are tinted and you can sometimes control it, and the new TV things on the back of every seat are truly amazing!

WHY is there no dairy free food?! I'm vegan but even for lactose intolerant people with more normal diets - there were absolutely no options! "meatballs and rice or pasta with a cheese sauce" - come ON! It's not that hard to make a vegetarian option that also happens to be dairy free!
