Pros: The plane and it’s crew were fantastic! The crew was totally customer oriented and provided great service for the entire flight.

Cons: It does no good to upgrade to Saga Class when you consider loading at Keflavik. A mob is herded on to a crowded bus and you wait at plane side with little room to move around. There is no priority boarding and the entire procedure might be acceptable in the Third World but certainly not in a country that has so much going for it.

Cons: Our flight was delayed 3 hours and we were instructed to rebook. After waiting over an hour to talk to an agent, we were supposedly rebooked to an Air France flight. After rushing to another terminal, the Air France check in agent told us she could not find our tickets, although the Icelandair agent gave us written confirmation. After being sent to the Air France ticketing agent (another office), we were told we were on a British Airways flight. COMPLETELY DIFFERENT AIRLINE. How were we supposed to know this? This was extremely frustrating. But BA treated us great and we can now see why they have such a great reputation.

Good 6.0

Pros: Very helpful and courteous flight attendants.

Cons: Chaotic boarding process, like cattle all in one mass. Frustration of short transfer time exacerbated by failure of the scanners to accept the boarding pass, slow handling of passengers by gate personnel, lack of overhead storage required me to check a small carryon bag.

Mediocre 2.0

Cons: I used Kayak to find my ticket and fill out my information (all kayak logos on top of the page and so on). However, when my confirmation email and e-ticket came in, they were issued by Budgetair.com. I had no experience with them and took it to be a reliable website since they were working with Kayak. However, I had to change/cancel my flight because of delayed passport delivery, and this is when everything turned very Ugly! I had to spend an hour over the phone to get connected to an agent with BudgetAir, who disconnected the line within 2 minutes saying: “please hold so I can pull up your information”. This game went on for 6 hours. I tried to connect with the airline directly to make the change, which was not possible since Budgetair had placed a restriction on this ticket. After 6-7 hours, which meant no work for me or lunch because I was sitting behind my desk with a phone on my hand, I got through an agent who was rude and impolite. He took 15 minutes to find flights for the new dates (I did it in 2 minutes on their website), and then told me to pay $315 in extra fess. When I inquired that the prices on your website for the exact same ticket is way cheaper than my original ticket price, he got angry and aggressive. Basically implying that I have no choice to take their offer as is, or let go of my original ticket price of over $2000. Long story short, DO NOT buy from BudgetAir if you like having a peace of mind!

Mediocre 2.0

Pros: N/A

Cons: Our flight was delayed 3 hours and we were instructed to rebook. After waiting over an hour to talk to an agent, we were supposedly rebooked to an Air France flight. After rushing to another terminal, the Air France check in agent told us she could not find our tickets, although the Icelandair agent gave us written confirmation. After being sent to the Air France ticketing agent (another office), we were told we were on a British Airways flight. COMPLETELY DIFFERENT AIRLINE. How were we supposed to know this? This was extremely frustrating. But BA treated us great and we can now see why they have such a great reputation.

Good 6.0

Pros: Very helpful and courteous flight attendants.

Cons: Chaotic boarding process, like cattle all in one mass. Frustration of short transfer time exacerbated by failure of the scanners to accept the boarding pass, slow handling of passengers by gate personnel, lack of overhead storage required me to check a small carryon bag.

Good 6.8

Pros: Very helpful and courteous flight attendants; low fare; ability to reserve a seat when ticket was purchased. Leg room was good.

Cons: No procedure for boarding except to have everyone pile up in one mass. The staff at the gate seemed irritated that we had not had our boarding passes clearer at the counter, even though we had no bags to check and the boarding pass directed us to go directly to the gate if no checked bags. We had to stand aside while the inpatient staff cleared us. Naturally as more passengers went ahead, we had to search hard for a place to stow our carryons.

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,
please send us an and someone from our team will get back to you promptly.
