Okay 4.3

Pros: The crew were very nice and helpful.

Cons: Providing a small snack would be great. Also the sears are extremely small so when the person in front of you reclines their seat all the way it induces a claustrophobic feeling and really limits your space. I suggest limiting the degree of reclining to not be as deep.

Pros: I liked that our flight arrived safely and was only delayed by half an hour. That’s really all.

Cons: - $100 baggage fee. For ONE bag. Other airlines don’t charge nearly that much. Apparently, it’s cheaper if I prepay online. What? - Paid $160 to have seats assigned to us but apparently if I show up early, I can totally skip this fee and just pick two seats next to each other. Had no clue because the website isn’t informative. - In flight, meals and drinks were served to a handful of passengers. Nothing was served to me or most people. There was no explanation why nor was there any offer to sell us food. Why? Is the food an extra option? Even if it was, how difficult is it to offer it to the passengers for an upcharge? I know they like upcharging. And it doesn’t explain why the drink cart just strolled by without even asking if I wanted anything. Drinks are extra too? - No personal fan on the ceiling. Come on. Only tiny, old aircrafts dont have fans. - Norwegian advertises free in flight WiFi! But this is very deceptive. You have to download a (terrible) app that doesn’t even so much as give you your flight information. The ONLY thing it does is stream movies. That’s it. It’s essentially their cheap response to having planes without personal LCD screens except it only has one feature. Overall, much more expensive and crappier than what you pay for. If another flight costs $100 more, just take it. This airline doesn’t have its act together.

Pros: My wife and I travelled from Punta Cana to Madrid to begin our honeymoon. We chose Wamos Air because their price was ridiculously low. However, we knew that at some point there will be hidden fees of some sort (e.g. seat selection, baggage, food, etc.). Little did we know that there will be be only few things we actually paid. We chose our seats for a reasonable price and, since we travel light, we were able to bring our carry-on and personal bags with us. We didn't expect dinner or breakfast and yet there were given to us! The seats were really comfortable and we liked the friendliness of the crew members.

Cons: People at the counter need to organize in a better way. Too many people for one simple process - check-in. Also boarding turned out to be madness. No structure, no organization, just get on the plane as soon as possible.

Mediocre 2.0

Pros: Nothing

Cons: I booked a Norwegian air flight and last minute was switched to Wamos Air. I had no other choice but to take this flight. 2 hour delay. I booked extra legroom and paid extra. There were not enough leg room seats on Wamos. I did not receive a refund. The planes are filthy and old. The service non existent. I will never book another flight or hotel with Kayak ever again. Horrible experience! I travel at least 50 Times a year and never have I dealt with such a nightmare.

Pros: I liked how simple the process was. What put you guys over the top was serving dinner and breakfast! Thank you! It was an awesome detail. And it was really good too. The coffee was so good. I thought the design of the airport was gorgeous! It would make a perfect start to a persons vacation. I gave a 3 in entertainment because wear I was sitting next there wasn't any entertainment, but I didn't mind at all because I wanted to sleep all night. I was upstairs and I loved it.it was my first time on a double decker plane. The crew was great!

Cons: I didn't like that it wasn't organized in Punta Cana, not even a little bit. I didn't like the process of buying the ticket online the website doesn't work well, it took forever and I even tried to look for a different company because it was too frustrating. I'm not sure why your price changes right before you buy the ticket but I think you should explain why with details because my friend was going to a ticket and went with another site because it wasn't clear. Also in Punta Cana they tried to make us pay a 20 dollar fee, trying to tell us it was obligatory. When we asked more questions then they said did you pay it online? We said we don't know, because nothing was clear on your site. They insisted we pay it and we asked more questions, in the end they didn't make us pay which leads me to believe it was a way to pocket money when they can, for example your company is not clear why the price changed and you are charging more. But maybe it is this dumb fee, but you have to tell the person. Ok say I pay it, then when I get to the airport they say I have to pay 20 dollars, after they make the person pay then they can look online to see if they already did and keep that 20 dollars.

Mediocre 2.3

Cons: My flight was delayed 2 hours, causing us to miss our connecting flight. We are now stuck in Botoga over night with no luggage. No change of clothes no toiletries. I just wanted to get to Aruba and relax, instead i had a very stressful time with your airline trying to resolve this issue. I would never fly this airline again.

Pros: It was all a smooth operation. In particular I appreciated that since my flight from Chicago was delayed and I missed the original connection, as soon as I disembarked in Reykiavick I found an SMS saying that I had been moved to the next available flight, and they even gave me a food voucher.

Cons: They don't give you food on the flight unless you pay which in principle is not a bad thing, and makes for a quieter flight, because it's not the case that everybody is eating, and eating at same time. On the other hand on a long transatlantic flight even a small snack would be appreciated.

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

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 prices, so it’s not possible for us to guarantee what other companies are selling.

We aggregate tons 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 don't guarantee prices we find.

Why aren’t prices accurate 100% of the time?
Prices on airline seats, hotel rooms and car hires 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.
