I would definitively avoid using this airline again. Multiple fctors. One kf them is the poor attending by the crew. Really bad service, water..3$?? Blanket 5$?? If you dont pay for food before your flight, crew totally ignores you when the deliver. They should offer a cup of water as minimum

Crew was always friendly

They don't offer complimentary water on a 7 hour international flight. This should be illegal. The man who checked me in at Berlin airport was offensive and uncooperative. Baggage fees are so exorbitant that they essentially cancel out the fare savings, and then you still have to pay for everything. Every leg of every flight was delayed due to poor scheduling from the airline. Both times transferring through Iceland I had to sprint with my roller bag through the airport to make my connection to my next WOW flight. I fly 20-30 times a year and my travel day back to Chicago from Berlin was literally the worst flight experience I've ever had. I will never, EVER fly WOW again.

Iceland air have a good product. They fly 757 and 767s that are clean and well maintained. Staff is very helpful, I changed over a flight during the layover in KEF and it was flawless, I got my checked bag as promised in CPH which was quite well done. So, they went out of their way to accommodate me. KEF does great with passport control and the lounge there is very nice.

KEF is a busy airport, always at capacity for travelers. Depending on the season it is hard to find a seat at the airport let alone the gate. During summer it is hard to even walk thru the airport. Depending on your abilities, give yourself time to get to the gate.

My flight was scheduled to leave at 6:20 pm 06/08/16. Took off at scheduled departure time but an hour into the flight had to turn around due to navigation system not working (2hrs flying time). Navigation was fixed, took off for 2nd time at 10 pm, fell asleep, awoke at 3 am to a messge over the intercom stating navigation had went out again and we had once again turned around and we were just outside of Chicago (6 hours flying time). I spent 8 hrs on a plane to fly to my origin airport. This was my first overseas flight and my first time flying with United. I got a frozen turkey sandwich and sorbert for dinner. I have been placed on an American Airline flight leaving at 8:50 am but I needed to be in London at my scheduled arrival time. I've lost approximeny 14 hrs of my trip including irreplaceable reservations that I've missed as well as very important time with my significant other that I get to see once every 2 months. I took off unpaid vacation time for this trip as well. Please contact me via email or cell phone to discuss what sort of compensation can be done for this very unfortunate chain of events.

Our flight wasn't on a Brussels jet, but United Airlines. It wasn't only a different carrier, but a different flight number. We only learned of this when we weee rising to OHare and asked a United Airlines pilot about it. He directed us to the right place. In London our itinerary indicated a flight on Lufthansa, but it was United and a different flight number, too. This is confusing and the practice needs to change!

The seats are not very comfortable, very hard and textured seats that just don’t feel nice at all especially on a long flight. I weight about 11 stone (154 pounds) and even I felt like I was taking up a lot of room in my seat.

Nothing remarkable

I got up to use the bathroom and I was seated in the 10th row. When I was trying to make my way back to my seat, the beverage service had started. They were at the 12th row and after bumping into me, the flight attendant asked me to back up and wait until the beverage service was over to go back to my seat. This was a flight from Frankfurt to Zurich, only about an hour long, and I would have easily spent half of it standing up had I complied with their request. I had to be pushy and ask them to just back up the cart 2 feet so I could get to my seat, which only took them 5 seconds. This was a very rude, illogical, and unreasonable request from the Swiss Air crew.

Throughout the long flight, the cabin crew was excellent. They were attentive and friendly. They avoided interrupting quiet time and rest time by keeping off the PA system (well done). The food was fantastic. We were lucky enough to get some business class tickets with points, and the food was amazing. Wine was excellent. This team was quite solicitous of my parent with reduced-mobility. And the bathrooms stayed clean throughout the flight. find this is often an areas where many airlines fall down. And it's too bad, because while I'm 100% sure it is no fun to clean a toilet while in flight, it is a really a big negative for the customers. Overall excellent attention to detail, with a cheerful and "can-do" crew that kept the plane "proper" throughout the flight and provided seamless service. Good stuff. Will fly again.
