Pros: Called BA (the carrier for our FinnAir flight) when I couldn't check in (didn't have a booking number that worked). Staff member did tell me that all was in order with our booking. He wasn't able to check us in anyway, as something was amiss with 'the system'. In the end all worked out fine, we just made sure to get to the airport early to make sure we got decent seats.

Cons: A bit nerve wracking to see online that our flight information 'could not be found' when trying to check in with the booking numbers I had!

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: Nice staff, very accommodating to the fact that we were late and missing connections. The ground staff in baltimore were communicative and really nice about the delay. The ground staff in london were super on top of it, handing us a new boarding pass as soon as we landed given that we missed our connection.

Cons: The back of the plane is just SO cramped. Seems humane to take out a seat in that back section. The food was pretty dry. Would have appreciated a bit more explanation of options. I didn't watch any movies - just tried to sleep. We took off three hours late. It's surprising to me that none of the BA staff spoke italian. Would have been helpful for the missed connections as I ended up stumbling through some spanish to help an older italian couple who didn't speak any english. it was surprising how little translation there was!

Pros: Plane was full. Finding overhead storage was tough. And, we checked luggage. The seat was small, but I had leg room and no one reclined their seat. There are a lot of extras one must pay for. But, the plane was on time and the crew was pleasant..People are accustomed to this treatment. There is no joy left in the flying experience.

Cons: I did not understand the entertainment system. I read a book.

Cons: Dear Sir or Madam: My two colleagues and I bought our tickets from BWI to Geneva, via London Heathrow, through Kayak as I have many times in the past. However, the Kiwi.com travel agency did not flag that the ticket from BWI to London Heathrow allowed for one piece of checked luggage, but the ticket from London Heathrow onwards to Geneva did not allow for any checked luggage. Also astonishingly, we had to pass through Customs, reclaim our checked suitcases from the baggage carousel, and check in again through Customs to board the onward flight, both coming and going through London Heathrow. In addition to the extraordinary inconvenience that we could neither transit at London Heathrow to our connecting flight without going through Customs twice and that we could not check our luggage through to our final destination, we also had to foot a higher baggage charge to allow for checking in our suitcases, now that we had arrived in London Heathrow only to discover this that our onward ticket did not cover one piece of checked luggage. Had we known that the seemingly better price posted by Kiwi.com on Kayak’s comparative offerings came at such a high price of inconvenience and additional expense for the luggage, we would have taken our business elsewhere. It was deceptive of Kiwi.com to engage in such practices, even if it disclosed these conditions in fine print (for no one would expect, nor have I ever seen previously in the hundreds of flights I have taken as a Million Miler on United), without flagging this. And similarly, it was irresponsible of Kayak.com to allow this “apples with oranges” comparison on its website. I’m making three more international trips in December, but I’m inclined not to use either Kayak.com and most certainly not Kiwi.com for future airline ticket purchases.

In addition to the extraordinary inconvenience that we could neither transit at London Heathrow to our connecting flight without going through Customs twice and that we could not check our luggage through to our final destination, we also had to foot a higher baggage charge to allow for checking in our suitcases, now that we had arrived in London Heathrow only to discover this that our onward ticket did not cover one piece of checked luggage. Had we known that the seemingly better price posted by Kiwi.com on Kayak’s comparative offerings came at such a high price of inconvenience and additional expense for the luggage, we would have taken our business elsewhere. It was deceptive of Kiwi.com to engage in such practices, even if it disclosed these conditions in fine print (for no one would expect, nor have I ever seen previously in the hundreds of flights I have taken as a Million Miler on United), without flagging this. And similarly, it was irresponsible of Kayak.com to allow this “apples with oranges” comparison on its website. I’m making three more international trips in December, but I’m inclined not to use either Kayak.com and most certainly not Kiwi.com for future airline ticket purchases.

Pros: The crew was great and made the flight comfortable and easy! They brought drinks as needed, free of charge, movies and headphones were provided, and the flight arrived ahead of schedule in London! A wonderful experience! Would absolutely fly again and was so pleased to find the deal on kayak!!!!

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 had to cancel my trip and was not able to or even reschedule even with flight insurance. I'll never utilize this airline/company ever again & am getting the word out. This airline/company like most are greedy & inconsiderate with their customers.

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.
