Mediocre 2.6

Pros: I got there

Cons: Endless waiting and lost luggage. Excuse was unpredicted weather conditions. It was snowing in Finland so they had to clear the Ice from the planes.. Snowing in Finland? How uncommon is that during December? I actually think most of this is poor ground handling In Helsinki.

OK 4.3

Pros: I have flown to hk with Cathay and American exclusively. I wanted to try Finnair because the price was very good for business. I now know why. The food is mediocre. The staff aren’t friendly or attentive. At $2700 it’s cheap compared to CX and AA but I know why now.

Cons: Service, staff and food.

YYZ
OK 4.6

Pros: One crew member servicing first class was in a mood “not to be here” - it is sad because of first class experience is higher than usual! It was just bad!

Cons: I honestly don’t have an answer for this, I guess these kind of crew should not on board especially in first class!

Excellent 9.6

Pros: While biased since I was in First class, everything was enjoyable and as expected of a first class experience. The free Wi-Fi on this flight made it extra special- can’t wait until its standard on all flights!!

Cons: Only real complaint is that Delta doesn’t seem to restrict size of bags taken as carry on and the time wasted but some trying to squeeze their obviously oversized bags into overhead compartments is painful.

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
Please send us an and someone from our team will get back to you promptly.
