I liked that the plane landed and I survived.

The online check-in didn't work, the phone customer service only answered after a 20 min hold and was unhelpful, the seats were so close that the seat in front of me hit me in the head when the woman sitting in it reclined, and the gate attendant was rude. People taking this flight and expecting to do work or watch the in-flight entertainment shouldn't. There is not enough space to use your laptop and when the person in front of you reclines while you are trying to read, not only won't you be able to read but you won't be able to watch a movie either (unless you are very short) since the screen is tilted accordingly.

The computer system really needs a lot of improvement. We were checking in with our infant daughter and it took 50 minutes to check in with a senior person helping the check in person and phone calls to their technical assistance. We were told an infant is difficult in their system, and our dual national daughter was another layer of complication.

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)

Online checkin wasn't working and the flight was oversold... After running through Heathrow after a delayed connection, we were told 5 min before the flight was scheduled to take off that it would be delayed. The coach seats were some of the smallest I've ever experienced (I fly 2x a month on average). The crew broke wheels off both of our roller bags.

The flight overall was fine. Equipment was good, although one passenger was stuck in a toilet for a little while - they had to take the door off to let him out - that was an interesting distraction. In-flight entertainment was good. Boarding and disembarkation was quick and easy.

The crew. Maybe it's because I'm neither young nor pretty. When they were giving out drinks I was missed - invisible I guess. And at a later point in the flight they managed to see me and I got a brusk "do you want something?"

The flight crew from the mel to lax route were excellent. One was especially attentive to my 2 toddlers and gave me a bit of a break, something that has NEVER happened in over 40 flights traveling with children.

I think something was broken in our section (mel to lax) as it was uncomfortably hot and the flight crew tried to get it cooler but could not. I’ve never experienced a flight that was too hot, usually the opposite. It was stifling.

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,
