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.

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.

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!!

We of course liked the cost and convenience of the Pittsburgh location.

When we missed our flight out of Paris due to a long wait at passport control, WOW customer service would not work with us. We did not ask for refunds or even hotel reimbursement we simply asked to be booked on the next days flight to Pittsburgh and WOW refused making us purchase new tickets for over $1000.

between lunch and supper snack one isle had only one water serving and my isle had none. So for 6 hours we had no water serving. This is why I gave crew rating OK only. Also the supper pizza snack was horrible. By comparison, United gives full drink cans so they last longer. I suggest Lufthansa also should serve full drink cans in long flights.

Prices are per person and are for e–tickets and include all taxes & fees in USD.

We attempt to get accurate prices, however, prices are not guaranteed.

Here's why:

We’re not the seller.
At KAYAK we don’t set the prices, so it’s not possible for us to guarantee what other companies are selling.

We compile tonnes of data for you
Our service lets you quickly and easily compare results from hundreds of travel sites at once. In this sense, KAYAK is a search engine and we can't guarantee prices we find.

Why aren’t prices accurate 100% of the time?
Prices on airline seats, hotel rooms and car rentals can change frequently. Several people may also be trying to buy the same travel option simultaneously. As a result, you may find, on occasion, that certain prices are no longer available.

If you have more questions or if you have a bad price to report to us,
please send us an and someone from our team will get back to you promptly.
