The check-in staff were very friendly and helpful.

I already knew I was going to pay $200 to ship my boards back home (I wonder if golf clubs which are roughly the same size cost as much,) but when pre-purchasing through the app for an "oversized" bag you have to put a "one" in the checked bag and a "one" in the oversized bag even though they're the same bag, but then they charge you for two, and when you tell the check-in person that you only have one bag of course they can't issue a refund. No, they tell you that you get to call customer service when you return home.

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.

Okay 4.0

Boarding chaotic- no clear lines people pushing ahead which I am not used to- my handluggage was ok’ed at origin in US- was pulled aside in Zurich based on my “ ticket”- it was perfectly well suited and not oversized. In plane half of overhead compartments were filled with coats when told that these should go under seats. No consistency between announcements and behavior of 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.

Even though the flight was very short, the team moved quickly through the cabin ensuring everybody had a drink and a snack. They looked quite concerned when I turned down the pretzel sandwich, so I accepted and found it quite good! Also, team made sure my parent with reduced-mobility had a good boarding and transfer experience.

As always, seats are narrow. And the "neighbors" were normal-sized. The usual struggle for elbow "air-space" occurred.

The seats on these flights are poor. As well as being narrow, there are bars on either side that dig in to your sides. My ongoing one hour domestic flight had more comfortable seats. Fod choice poor. Chicken Curry or Cheese/Tomato Lasagna. If I want a vegetarian meal I'll order one beforehand. Give me two meat options. This isn't the first time I've noticed this. Is it cost cutting? Seems like it to me. Not impressed.

Fligth attendants of British, Iberia provided excellent and friendly service. Some of London British Airways desk and gates officcers, gave me really poor service.

My flight to London was pretty good,. Service was excellent.. But not my transfer to Madrid , I lost my conecttion. On London airport, I was sent back for the gate because I showed up early and they ask me to take care of the screen and wait for the gate #, when they showed the # , I went to the gate and was told my flight had left an hour ago and sent me back walking . I was wearing an orthopedic shoe, due to a toe fracture and i had to walk again all this long distance back to the terminal.!! British airway gave another flight and had to pay $279 dlls for a ticket to Madrid.2 hrs later. My flight was by Iberia and the service. was excelent. I wonder if the insurance , I bought initially will cover something of the $ 279 dlls ticket ? Fligth back to EUA was by AA and service was excellent

The stewardess’ didn’t even respond to the call light and after myself and sister walked back there, nothing was done. Stewardess’ sat and talked in the back and never walked around. When the finally brought drinks, never even asked why the light was on. They also were extremely unfriendly because our incoming flight from Malaga was late . All 4 pieces of luggage missed the flight and in NYC we had to ask for robes to sleep in and tooth brushes. we felt horrible flying the next day. Three pieces of luggage came 2 days later that we had to go back to airport to get. The fourth was delivered one week later with only 3 wheels!

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.

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.

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.
