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.

I liked that even though it’s a budget airline I was thourpughly comfortable from start to finish. Staff was very nice.

The seats are what you would expect of a budget airline but i didn’t mind it so much. The only thing that I wasn’t amazingly pleased about was that even for water I could only get a water bottle which I had to pay for.

The movie selections and comfortable headsets made it possible to watch three movies uninterrupted. The food selections were well prepared. Flight attendants were helpful and efficient.

Boarding is always a bit of chaos when our seats are right in the back. People further up insist on boarding early and block the aisles in the process. Multiple levels of passport control and baggage checkout are chaotic, but that's for most all flights coming into USA? VIrgin/Delta handled it well enough. By the time we got through passport control in Boston ur bags were waiting and we had no problems at all.

Nothing because I did not take this flight

That we were there 50 minutes before departure and it was not clear that we had to be there an hour before departure. It’s not that we didn’t plan to be earlier (we did) but our Uber driver took an awful route and turned a 50 minute drive into 2 hours. Given there was nothing else we could do, we would have appreciated a little more leniency or at least more clarity on the hour rule.

Entertainment

The cabin crew didn't have any personality, and didn't look happy most of the time, a smile goes along way. When you look for a cost effective flight especially when flying with family including 2 young children you think it is good that the flight costs were quite good, however when you add in the additional baggage fees each way and the reserving you seats so you can all sit together the overall flight costs including the extortionate food prices on board makes them out to be much the same if not higher than that of one of the premium airlines that already include all those things in your flight cost. Not to mention when arriving home in Boston around 40 passengers bags had been left in London and there was NO Norweign staff available to help with this, it tool numerous requests from passengers as well as the flight services people to get a Norweign member of staff to come and help. SO there were a lot of unhappy passengers. I will be seriously considering whether i use Norweign any more in the future because of this.

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.

The flight itself was very enjoyable. The only negative aspect was that the first leg of the flight was delayed long enough that I almost missed my connecting flight and my baggage was lost.

The real reason for the negative review is a combination of the cost of this flight, loss of my baggage and poor service after the flight. I paid nearly $4,500 for an economy ticket from New York to New Delhi. The first leg of the flight, from New York to Zurich was delayed long enough that I made my connecting flight to Delhi within seconds of them closing the gate and as a result my baggage was lost. Once I got to Delhi I had to take a connecting flight to Goa and then drive an hour to my destination, where I was attending a good friend's wedding. All of my baggage was lost during transit by the airline, and unfortunately they never delivered by baggage to my hotel...so I was without formal clothes and normal clothes for the wedding for 4 days. The customer service line was no help, and the airline refused to deliver the baggage to me...the closest they would bring it was the Goa airport which was an hour and a half away.

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.

The seats were roomy and comfy and I was glad I didn’t have to pay extra for a seat like other airlines.

Boarding was very confusing and the customers reacted by plowing Willynilly down the ramp nano seconds after the physically challenged were wheeled on to the plane ignoring the airline staff at the gate. I went with the flow praying I would not get arrested. We boarded a total of 40min late . Second if I am paying for my baggage I should not have to wait 30-40 min for them to come out at baggage claim.

Legroom is above average, but at expense of seat comfort. Food is good but expensive. Crews were attentious and courteous, but not a strong differential from other airlines. Entertainment was good and easy to access.

Boarding in all of our 4 flights was chaotic and a combination of lack of organization from Icelandair and discipline from passengers. Space for boarding is scarce and confined. And when they call half of all passengers of a full 757 or 767 to board at the same time... the law of the jungle is stablished. Even with just a little more effort and organization from the airline it would be possible to make this a better experience for all passengers. Be aware of what you are told when you buy your tickets. They sold economy tickets to us and then charged a lot for bags telling us our tickets were economy light, even with their own receipts or tickets not mentioning anything about light on them.

The whole flight was great quick boarding, lots of leg room, good entertainment, a USB charge port, good lighting, and the crew was very nice and helpful. I enjoyed the flight and would like to fly Virgin Atlantic more. Finally, you are the 3rd best flight, I have ever take, and the 2nd best airline I've been on. Flew Business Class on Swiss Air once to Geneva (#1) and all the flights I have had with Porter Air are comparable to your airline, but the free cookies and beverages at Porter's terminal in Toronto wonderful.

A couple things went wrong on this trip, my checked luggage got misplaced for a day, and a nice women in baggage claim told me what was happening and a nice man handled my claim and my bag has now been returned to me. The bigger thing is my flight bas delayed taking off by 3 hours. Let me start that I would rather have a part replaced on the runway then not, safety is paramount. The fact is my flight took off 3 hours late from London (VS11), and got to my destination (BOS) 2.5 hours late. Kudos to the flight crew for getting me to my destination faster by gaining a little time. Plus, since BOSTON was my final destination it was all fine this time. But if I had had to get home to the elder person I take care of or my teenager it would been a problem. Again, I'm annoyed, but I do understand the reasons and they are valid and preferred. I have heard that airlines to keep their flight rating high, wait for planes to leave the gate on time and then do repairs on the tarmac. If this is still a SOP for airlines you should change the way the statistics are collected and figure out a way of not perpetuating this type of disincentive. This is just hypothesis on my part, and my whole trip had little negatives.
