It's OK to ask to pay for everything as long as the flight is on time. But no matter what was the flight - Boston to Iceland, Iceland to Paris, Paris to Iceland and Iceland back to Boston - flights were late - almost missing the connection in Iceland back to Boston. And the fact that you have to take a bus at the airport in Iceland for your connection and wait 20 minutes in the bus is just not acceptable...

It was a pleasant enough trip. Friendly crew, surprisingly decent food for a flight, and some decent entertainment available, though admittedly my headphones broke within a couple of hours for some reason, but by then I was nearly asleep anyway.

It wasn't very comfortable and I had basically no leg room, but then, I sat in economy, so I can't be too surprised by that. Otherwise it was a good flight.

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)

My flight from Chicago to Frankfurt was on a very large plane so I have no complaints, but, the plane chosen from Frankfurt to Tel Aviv was much smaller, and packed to the gills, with passengers, and luggage, and crew.

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,
