Pros: Finnair is always perfect. Always on time, professional, clean and comfortable. They give free coffee, water and blueberry juice.

Pros: The lie-flat seats were just great .

Cons: Storage space should be made available beside the seats , especially during take-off and landing. There is none right now , and that's in Business class.

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: Having read horror stories online about booking with Kayak's partner Justfly, I was prepared for the worst (last-minute cancellations, partial refunds, all-around crummy service). Actually, my Finnair flight was great - it was operated by BA, so it was a nice new double-decker Airbus plane. It was maybe 3/4ths full, so I nearly had a row to myself - shoutout to the jerk who decided he was entitled to the aisle seat. The flight was smooth and easy and best of all, it cost a fraction of what the BA price for a one-way from SFO to LHR cost.

Cons: The food on BA continues to be meh, but what most people don't realize is that ALL airline food is meh, because your tastebuds don't work properly 30k feet in the air (it's a scientific fact).

Cons: I was bumped off my flight and re-routed return to NYC. Flight was supposed to depart at 10:25am and flight they put me on left 1:05 Pm and the connection was not even Finnair, but Icelandic air. The Kayak site did not alert about extra charge for confirmed seat before I had paid in full ticket.

Pros: Everything was nice.

Cons: Nothing to complain about.

Pros: The crew and service were welcoming, caring and attentive

Cons: Many people bring the own headphones these days, but I didn't and provided phones were so-so, volume on touch screen was jumpy too,

Pros: Not a lot.

Cons: Our flight got delayed so American Airlines Auto switched us to a flight leaving a day later with a 17 hour layover. When I called to get it fixed I waited on hold for 30 minutes before I got through. Once we got on original flight they gave away seats we paid extra for and gave us no refund.

Cons: Finnair are hellbent on trying to sell goods and continuously interrupt the movies with their confounded announcements every 15 minutes very annoying. If i wanted to buy something its in their mag and as a regional flight it should include some form of nourishment other than juice or coffee one off, tight fisted and not a descent selection of food either

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: Plane was clean, plenty of leg room, cabin crew was friendly, flight was on time.

Cons: Checking in was a nightmare of inefficiency. I couldn't use self-check-in for my bad because I was flying to America and for some reason, this meant I had to hand my suitcase to someone rather than just putting it on the conveyor belt. There were about 8 people ahead of me, and yet it took a solid hour of standing in line waiting to get to the counter. How it could possibly have been so insanely slow is beyond me. When it was finally my turn to submit my bag it literally took 30 seconds. And yet I had to wait an hour. Grade: F-

Pros: It was relatively inexpensive. I didn't mind the food/

Cons: This flight was operated by BA. Seats were incredibly uncomfortable. When the guy in front of me reclined his head was practically in my lap. TV's were crappy and the in-flight selection was mediocre. In flights announcements were very loud through headphones.

Cons: The passenger sitting next to me smelled REALLY bad. Like he hadn't washed himself in weeks. Other passengers around me got a whiff too and also reacted the same. I asked the main crew member from my aisle for a seat change but he came back 10 mins later saying there was nothing else available. Later when I was walking around to stretch my legs, I saw there were AT LEAST 10 seats open in the next cabin. Why lie? The entertainment system touch-screen was not working properly and the headphones kept falling out of my ear.

Pros: Comfortable

Cons: Seat in front of me was mostly lowered in a position that caused an uncomfortable force against my knees. My neighbor had to place his knees in my sitting area for the very same reason. Otherwise everything was great.

Pros: Nothing

Cons: Kids running up and down isle stewards just walking past. Never made announcement for boarding. Worst flight ever.

Pros: Plane was clean, plenty of leg room, cabin crew was friendly, flight was on time.
