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!

Pros: Check in was simple and efficient, boarding was easy, leg space was sufficient, air hostess where polite and plane was clean prior to take off. Landing and take off both on time.

Cons: Two toilets for 100+ people meant long queues for the bathroom throughout the flights. The toilets were not even once cleaned in a flight of 4 Hours, meaning that by the final hour, they were a complete utter disaster in terms of hygiene. Pilot made a complete mess of descending and landing.

Pros: I was amazed how comfortable we were in economy. Pillows, Blankets that felt like cotton. I would fly Lufthansa over an american carrier any day. We passed through the business class cabin on the way out and I can only imagine how much they were pampered!

Cons: Since flying in the US has become expensive and painful I was not expecting much from this flight. They exceed my expectations by so much that I cannot think of anything I would change. (Ok, my chicken was a bit over cooked but that was such a minor thing.)

Good 7.0

Pros: Great crew, especially on a long-haul flight. Decent food, considering how many people they were serving. Best bathrooms I have ever experienced on a large plane.

Cons: Legroom, legroom, legroom!! If we are to be treated as sardines, at least pack us in oil. It gets worse every time we fly. Crew agreed; the airlines need to be put on notice. It makes their job impossible.

Pros: Crew was great.

Cons: The layover time was too close for FRA. By the time everyone deplaned and was shuttled to the terminal by a bus it was already my boarding time. I had to rush through the passport control feeling nervous The seat pitch of the flight was narrow. I could not use my laptop once the person in front of me reclined.

Excellent 10.0

Pros: Loved Finnair. Hated Justfly.com. If you own this company, you need to end up like Blockbuster or Circuit City.

Cons: If I would have purchased my tickets from Finnair.com, I would have had a much better experience. Kayak found me a good price but purchasing the tickets through Justfly.com was the biggest mistake of my life. The trip ended up costing me $285 more than what I budgeted and there was zero customer ser

Pros: Fell asleep and didn’t even realise. Finnair is very friendly and the staff are super nice. I was very thirsty and asked for two cups of water instead of one and the lady was not hesitant to give me two cups in quick succession. Very good air company

Cons: Nothing really too bad, you get what you expected. May of been nice to have a free sandwich as it’s a non stop flight - this is because Lufthansa has one stopover and offers a free sandwich and drink.

Pros: Boarding was quick and efficient. Flight crew was polite, helpful and friendly. Had adequate leg room in coach, added plus was the flight was not crowded so did not have anyone sitting next to me. Did not feel squashed and claustrophobic as a result. Food was satisfactory.

Cons: Was inadequately fed on the Houston to London leg. Got nothing but a nightcap. The following morning I received a cold, stale croissant as part of a lunch box for a preschooler, nothing warm, no protein after 8 hrs in flight. I could not check in online.

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.
