We had a newer plane. I LOVED that the seatbelts had a little more room, and also that each seat had it down screen. I really enjoyed the new pre-flight video; it was entertaining and I appreciated that it allowed the crew to get ready, rather than demonstrate a seatbelt for us.

I am not sure how boarding groups work, but I will never understand why we don't board from the back of the plane to the front. People waiting and trying to load luggage or climb over others makes the pre-flight more stressful than it needs to be. (This is obviously not specific to you airline.)

American continues to surprise through their lack of consideration and cheapness Prefer to have seat empty on the front rather than move passengers that are loyal frequent flyers. The most important point for American is you have to pay for everything including for flight status. No longer miles flew but how much you pay them

Flight was cancelled on our way back home from Gudalajara, was speaking to a representative for almost 2 hours to get me on the next flight the flight representative forgot to put me on hold and told everyone how rude i was, i was not rude i was just trying to get home. The representative couldn’t help me so i asked to be transferred to a manager, after 2 hours i was transferred and the manager hung the phone up. Long story short i called back spoke to another manager Yana and she was the rudest lady ever! She basically told me for waiting to long i will have to be placed on a flight 2 days after my cancellation flight. I started to cry because i needed to be home and she basically did not care so i took the date. Never again and i will warn everyone about this airline and their customer service!

This flight was less full so we could spread out more, but it still was not overly comfortable. My boyfriend forgot his phone on our last flight, but the crew was very helpful and got it back for him, which we appreciated very much.

Icelandair has an original lifestyle intro video and safety video. Made me want to experience Iceland. Airport in Iceland was amazing.

Didn’t communicate well with us when airplane was late or make any announcements about boarding. No luggage allowance. Cost was INSANE to check a bag...$95 USD one way and $86 EURO return. The most outrageous prices we have ever come across! Food was not provided for free on our oversees flight. You had to pay again, an outrageous price for a small meal. Overheard crew members talking about others on board and drop the f bomb. Not very professional.

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,
