British Airways overbooked this flight and made it unclear if I can board my flight. Overbooking is such a greedy behavior and airlines should refrain from engaging in this dubious policy. It is the second time this happens to me with BA.

Flight way delayed 3 hours. Staff gave no information and wouldn't help rebook us onto other flights. They gave us food vouchers 2 minutes before we finally boarded, so we couldn't use them. The food on the plane had spoiled so we were all starving on the flight, and we all missed our connections. Horrible experience and wouldn't fly with KLM again.

Most Improved Player - Finnair has done the best experience in overall long haul flights out of the 40plus airlines I have flown in the last 3 years; brand new planes, nice and diverse cabin crew, beautiful lightings videos details chocolates etc, best entertainment system in the industry, and things always go smooth in Helsinki airport. Awesome imrpovement over recent years.

Big struggle for airlines still remains varying quality customer service. Finnair still seems to struggle with this occasionally. Finnair can work harder to keep customer service quality high. Hate to say it, but perhaps letting the bitter, last generation flight attendants who seem to have a grudge about the decline of the glamour and benefits of the job as flying has become commonplace with more competition (seen this on Finnair & N America’s older airlines line United)

Brand New plane. Great German entertainment. Crew were very efficient but didn't show up with drinks as often as in the past but still more often than other airlines. Overall a wonderful experience.

Took two hours to start dinner service without a reason. Turbulences and a passenger with long legs were impeading my sleep but not Lufthansa's fault.

I like Finnair, the crew, the service.

I was not able to check in online within the 24 hrs prior to the flight as the Iberia system kept flashing and "error"message. Therefore, I was not able to pick a seat, which I would have paid to upgrade if necessary, but instead I was assigned a middle seat as a last option, at the counter, and paid for an exit row which, except for the leg room, was just as uncomfortable!

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,
