Plenty of leg room, and I got an empty seat next to me! Food was served on time (an hour into the flight, and about two hours from the destination). The options were decent particularly the caserole in terms of portions. Plenty of overheard compartment space, even with a nearly full flight.

The arm rest between seats doesn't raise to the full upright position, only one-half way. The TV needed to be reset by the purser due to it being stuck on kiddie mode. If you're a snacker, bring food.

Airplane was nice.

I paid $90 for economy comfort for my flight and did not get an economy comfort seat. I am very disappointed with Finnair in this. They will not refund my money at the airport and now I need to go through their home office for a refund. It was bad enough not having any extra leg room on a red eye when you are over 6 feet tall but now I have to jump through hoops to get my money back.

Decent flight from SFO to HEL, friendly staff ...

Ran out of food options from SFO to HEL. I was sitting towards the end of the plane ... and no more chicken so got stuck with the pork and mashed potatoes options. Need more coffee aboard the flight. ANA cleans the bathroom periodically, and wouldn't be bad to do the same on long flights. The arm rest between seats don't go all the way up, only half way. If the person in front of you is asleep during meal service, the FA (flight attendant) won't lift the seat and it may be a very uncomfortable meal experience. Other airlines will have the FA do it themselves. ...and you need to be careful about staying awake to get food (otherwise you can get forgotten).

That the flight only came in 15 minutes late.

An old beat up plane in desperate need of renovation especially for a long haul flight. Only one nice flight attendant who tried to help. Others not interested. Terrible seat that I tried to move with no success. Did not eat anything or watch any entertainment. Very unpleasant experience. I have flown this route many times and next time I would fly Swiss through Zurich or Geneva as I have done before.

Flying BA is like flying any other American provider. The service was good, the food was meager and mediocre. We flew the same route with SWISS Air a few months ago and the seats are a bit more comfy and the food, snacks and drink were more frequent and delicious.

Pre clearance in Dublin flights to US is nice. It's helpful for traveling to/from Ireland as they tend of have the only direct routes from a few US cities.

Food is terrible. The planes are old. No USB on many of their planes (some have been updated but not all) Can't properly use your own headphones with the entertainment, and the headphones they provide are absolutely horrible. But worst of all is how crammed it all is.

The shortest flight time between NYC and St. Petersburg Russia. Good connecting time, smooth transition in Helsinki.

I have never used this airline before and as it was highly rated, I was glad to give it a try. The seats were crammed together very tightly, even for me, a short person! So, the flight was uncomfortable. Then the food was poor. The selection of films was uninspired. The service was indifferent, disinterested, ungenerous. There was something meager, miserly in the whole experience. They are obviously maximizing profits at the expense of the customer, who seems totally disregarded. I would not choose this airline again!

Prices are per person, are for e–tickets and include all taxes & fees in GBP.

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 prices, so it’s not possible for us to guarantee what other companies are selling.

We aggregate tons 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 don't guarantee prices we find.

Why aren’t prices accurate 100% of the time?
Prices on airline seats, hotel rooms and car hires 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.

More questions or if you have a bad price to report to us
