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.

Pros: Finnair cabin/seats, clean, quiet and comfortable airport in Helsinki

Cons: Not only the first flight got delayed for over 2 hours. I had to re-book the second - connecting - flight because of that. Now it made my layover instead of 1 h 45 m - 5 hours! Then the second flight got delayed!! So instead of 5 hours layover it was over 7 hours!!! Very inconvenient and upsetting experience. The only reason I booked these particular flights is because they were advertized as "the shortest trip" time on your website...

Pros: I sat with nice people and was happy each seat had a screen but of coarse it didn't work

Cons: Seat and foot room was extremely cramped , and I'm 5"4 115 lbs, seat was horribly stiff and uncomfortable , the entertainment system broke throughout the plane an hour into flight, you never saw crew in less they were serving food, it was very very load , it was a pretty awful experience and I'm not looking forward to the flight home at all

Excellent 9.6

Pros: Having read horror stories online about booking with Kayak's partner Justfly, I was prepared for the worst (last-minute cancellations, partial refunds, all-around crummy service). Actually, my Finnair flight was great - it was operated by BA, so it was a nice new double-decker Airbus plane. It was maybe 3/4ths full, so I nearly had a row to myself - shoutout to the jerk who decided he was entitled to the aisle seat. The flight was smooth and easy and best of all, it cost a fraction of what the BA price for a one-way from SFO to LHR cost.

Cons: The food on BA continues to be meh, but what most people don't realize is that ALL airline food is meh, because your tastebuds don't work properly 30k feet in the air (it's a scientific fact).

Cons: When we checked in, we were told we didn't have seats because the plane was overbooked. We waited at the gate for information. The attendants were curt and not helpful, they told us they had no information. After the plane was boarded, we were finally given tickets with seats and rushed onto the plane. When we arrived at the Sarajevo airport, our luggage and the luggage of many passengers did not arrive! We waited in a line for 1.5 hours to put in a claim for our suitcases. It was not a good experience.

Good 7.6

Pros: The meal and drink service was quite good. The stewards/stewardesses were very attentive and kind.

Cons: There is not enough leg room. There is even less room if the person in front of one's seat has the seat reclined. The seats barely recline at all, so sleep is impossible. Sleep would be possible if there were enough room to rest one's head on the tray in front of the seat. This is impossible if the person in front of one's seat has reclined his or her seat. Thus, sleep is totally impossible on this aircraft. The sinks in the bathrooms also need to be deeper and need to drain more quickly.

Pros: Boarding staff & crew were fine

I have been in long-range (16 hours) flights that were more comfortable than this. If anything fell on the floor, I couldn't retrieve, I couldn't sleep at all & had contorted joints & a body ache when we landed. To design such tiny seats is truly inhumane.

Cons: Cramped, cramped, cramped!!!!! The seat pitch was just so uncomfortably short so much so that when the person in front of me reclined his seat, the TV screen was a mere 1-2 feet away from my face making it impossible to watch anything without getting crossed eyed or a headache. This unfortunate situation has influenced this review greatly particularly because this wasn’t a 2 hour flight but a long haul one.

Pros: I last traveled on British Airways in May of last year (2015) and the food was beyond dreadful. Therefore I was very pleasantly surprised that there has been a huge improvement. They were very generous with the drinks and the food was plentiful and quite a reasonable standard for airline food (they gave two full meals from San Francisco to London, whereas most airlines give one meal and one snack on that route). They actually checked us in on the earlier side, we took off very promptly and got to London early. It was nice to be on time for a change - so often I find airlines run a bit late. Staff were all pleasant and helpful. Pilot's messages were pleasant, friendly and even a bit informative.

Cons: Web check-in ahead of time was a total disaster. I got an email telling me I could check in 36 hours early and "secure a good seat" but neither of the 2 sets of codes they provided in the email would work because it was all about Finnair but actually the flight was being run by British Airways. I spent about 30 minutes on the 'phone trying to get the appropriate sequence of numbers and letters to enter so as to check in and get a good seat - still nothing worked. This was at 5:45am - I regretted the time spent when I could have gone back to sleep. My daughter later spent a further 90 minutes trying to figure it out, only to be told finally that our only option was to get to the airport early and check n there which was what we did. It was beyond irksome. Please note, if the airline actually flying is different fro the booking airline, the locator number for check n will be DIFFERENT and needs to be provided to the customer to avoid a great deal of hassle and confusion. We gt particularly unlucky because BA computers had a glitch that day but the general point still stands.

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.

Okay 5.3

Pros: The plane was clean but the seats are not very comfortable

Cons: Icelandair makes you think that the ticket is a real bargain but the luggage charges to check one bag per person cost as much as the ticket, then you have to pay for food and many seat choices.

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.

Excellent 8.0

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.

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.

Excellent 9.6

Pros: Having read horror stories online about booking with Kayak's partner Justfly, I was prepared for the worst (last-minute cancellations, partial refunds, all-around crummy service). Actually, my Finnair flight was great - it was operated by BA, so it was a nice new double-decker Airbus plane. It was maybe 3/4ths full, so I nearly had a row to myself - shoutout to the jerk who decided he was entitled to the aisle seat. The flight was smooth and easy and best of all, it cost a fraction of what the BA price for a one-way from SFO to LHR cost.

Cons: The food on BA continues to be meh, but what most people don't realize is that ALL airline food is meh, because your tastebuds don't work properly 30k feet in the air (it's a scientific fact).

Mediocre 3.0

Pros: I sat with nice people and was happy each seat had a screen but of coarse it didn't work

Cons: Seat and foot room was extremely cramped , and I'm 5"4 115 lbs, seat was horribly stiff and uncomfortable , the entertainment system broke throughout the plane an hour into flight, you never saw crew in less they were serving food, it was very very load , it was a pretty awful experience and I'm not looking forward to the flight home at all

Okay 5.3

Pros: The configuration of the seats are really awkward. Seems very interesting at a glance, but not so nice when you have to sit in it for 10 hours. The business class seats are very narrow. I'm pretty petite so it was okay for me, but I think an average or bigger than average person would have a hard time turning at all while the seat is in lie flat position. I had a window seat which gives you more privacy as long as you have the divider up between you and the passenger next to you. You are really arm length away from each other though. And! You can't have the divider down the entire time because they serve your meals by passing it over to you across your neighbor through the divider. The divider is also required to be down during taxi, take off and landing. So, I'd imagine it to be very awkward if you're sitting next to a total stranger. You also have to straddle over someone's legs if you want to get out of your seat to the bathroom if you have window seats.

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.
