Very good seat, very comfortable, good food, and good service.

It was a good flight, very comfortable seats for sleeping in business class. Probably the most comfortable business class seat I've ever had (20+ times in business class on various airlines). Service was good, but the only downside is my screen didn't work and it had to be reset multiple times to get it to shut off. I had to block my eyes because the screen was white almost the entire flight and I wore an eye mask when I slept. But when eating and reading in my seat, my eyes hurt because the only way to turn the screen off was reset it and the screen would only be off for a few minutes at a time.

Everything was wonderful! AirBus seats are more comfortable to sleep in as compared to the Boeing planes.

All reviews good because...flight from BWI to London ,economy seats was miserable. I usually book 1,step up from economy but this would have added 1500 bucks 1 way. Bit the bullet and upgraded for retun flight, otherwise all ratings would have been rock bottom.

Great. It was awesome to have boarding from the front and back of the plane as it made the process go very quickly

It was okay. The airplane was a little smaller than a flight from Thailand to Helsinki.

Wish that everyone would board the back of the plane first. Also let kids on first. The gate wasn’t open at arrival and we waited 45 minutes to takeoff. They made up for time in the air.

This was an absolutely exceptional flight. The flight attendants were extremely attentive and very friendly. They seemed to go out of their way to make us comfortable and to make sure that we had everything we needed., We were in business and were very happy with the size and the details for our pods. We would definitely recommend Finnair and will definitely be flying with them again.

We had an excellent trip with Finnair. This was our first time and we’re very pleased. The only issue was with the boarding - it was a little bit confusing and needs a little bit of streamlining.

Crew very lovely. Arrived an hour late due to bad weather. We were given new tickets to an other flight but it could have been organised better, so we did not have to run through the whole airport to.

Lufthansa flight LH04414 from Munich to Washington DC, was fine. Efficient and safe!

Flight was great. Smooth flying, movies good. Open seats allowed for good stretching.

Missed flight. Requested assistance for my father and he did not receive it in Paris.

We were rebooked twice to the point that we didn’t even fly Lufthansa that day. We apparently though had to pay Lufthansa’s baggage fees for our sports luggage. The United Airlines Counter in Anchorage charged us for oversized bags, not sports luggage and told us it was Lufthansa’s fees. How is this possible?

I fly to Germany every year and prefer the most direct flight routes. Lufthansa offers this route, allowing me to fly from my home airport directly to Germany. The food and service were excellent. The staff was most accommodating, very professional, and friendly. The only issue I did not care for was the seating arrangement. I fly business and did not appreciate the configuration of the business class. Understandably, you will always have someone seated next to you, but then install a separation screen to allow for a little more privacy. United and British Airways are miles ahead in creating a more personal space. Lufthansa should do better.

The crew was very professional, no food was served. The flight was delayed which impacted my connection at Frankfurt to Chicago… It was very stressful because it was out of my control. Had I missed my connection, it would have been extremely disruptive and inconvenient as I would have had to make other arrangements to fly to the United States.

I meant this flight was not good, the one from Tirana to Frankfurt was better!

It was very good, good food good stuff, The toilets were a little stinky.

The flight was delayed by an hour. Made the connection uncomfortably tight.

The aircraft was old, there was no charging sockets, and the seats were narrow and uncomfortable even though I had exit row premium seats.
