I think this airline has an attention to detail and level of service which surpasses most other airlines. Whilst remaining competitive these factors make traveling with Finnair a far more comfortable and attractive proposition for me. In addition, Helsinki airport must be one of the best around.

The cabin crew were pretty good. That's about all that was good.

I paid almost $400 for upgraded seats. When I got to the airport-- no seats-- both ways!! i didn't even have regular seat assignments. I had to choose from the last few seats available. The ticket agent, the gate agent and the cabin crew all did nothing to make up for the fact that their system screwed up and stuck me in a cramped coach seat in the back of the plane for 11 hours-- TWICE! Beyond that, KLM must have one of the oldest fleets in the sky. Both ways LAX->AMS->LAX, I was on a 30-35 year old 747 with no wifi, no power and a ten-year-old entertainment system. Never again.

Both flights, outgoing and returning, had the same problem. My family was spread all over the plane. My wife was in the back, I was in the front, and my two kids (ages 2 and 4) were split apart in the middle! Aer Lingus won't allow kids to be checked in online or over the phone so we couldn't address this until we arrived at the airport. At the check in desk, Aer Lingus personnel who are usually very accommodating told us "I'm sorry. It's a full flight. You'll have to talk to the flight crew." As if boarding a an international flight with two toddlers isn't difficult enough, now we had to do it without knowing where are seats were. All I can say is thank God for the accommodating passengers on our flight. The flight attendant was not helpful so I had to ask people myself.

We received an upgrade to Business class that we submitted a bid for -- it was the difference between heaven and the usual too small, too squashed intercontinental experience. The whole experience post-upgrade was top notch, from the service to the food. Thanks, Are Lingus!

I am used to flying Frontier because of cost but recently traveled Delta and boy did I feel completely spoiled! Not only did my other half get our bags for free due to his status with Delta but the amenities they offer and the comfort of the economy seats compared to other airlines is a major difference. As a chronic pain patient, if I can find a Delta flight for a little more, I will be booking with them for sure! Highly recommend them!

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,
