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

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.

Flight delayed over an hour. They said they would hold our connection but then did not.

Major problems checking in at Alaska counter. They could not find our booking code because it came from Finnair.

Do not use KAYAK or Finair for future travel. Unless you purchase the tickets directly from the airline, you were going to have a difficult time checking in. Kayak canceled my flights twice and ended up causing great difficulty in me getting back from Europe because they double sold my tickets between American Airlines and Finair. The event caused significant delays and led to me having to rebook my flights.

The staff were all particularly great. The plane was clean and fresh. The bassinet worked great. It was all very nice.

Boarding uncomfortable. Stewardess said I would have to check my carry on as there was no room in the overhead bins. Another passenger helped me find a spot.

No vegetarian option was provided for the regular meal or the pre-landing snack.

The Scandinavian flight was excellent, however the second flight was partnered with TAP Portugal which was not so good. crowded gate area with no chairs, delayed flight, bad boarding process, no entertainment system onboard, and the baggage didn’t get to the carousel until well over an hour which caused our taxi that was waiting to leave. Love SAS, hate TAP.

Great logistics and timeliness as we arrived quite early. Flight smooth and fast. Excellent entertainment. Plane itself was a bit tired and the crew mostly indifferent. Baggage took forever but that’s on CPH. Would use SAS again for sure.

Will not recommend SAS for business travel. Food was so-so. Service was very good. First leg was very good. Second leg from Copenhagen to Barcelona was terrible. We paid a LOT for business class and to have seats worse than most coach seats with no entertainment and no charging available for 1/3rd of the whole trip was not acceptable. Very disappointing. I thought they were coming back in the U.S. with style, NOT YET.

I do not have a problem with the airline but both my two suitcases that were supposed to go from Hawaii to Copenhagen didn’t get on the plane in Seattle. I arrive on Monday the 21st at 10:30 in the morning. I did not get my two suitcases before Friday late afternoon that is unacceptable.

No choice of food. Needed to pay more even for a can of coke!!!

The seats were really close together and hard to get comfortable. The food was okay. The cheese was amazing! I loved the cold towels they gave us.

When my flight was changed from delays they were quick to rebook me.

I really enjoyed how clean and big the aircraft was, as well as how friendly the crew was.

Airline left me stranded in the U.S. gave me an unrequested refund of 40% of booking and canceled my trip back! When I asked why, the said “we don’t have to tell you why”. “But you can rebook”. Never again! Paid 2x and rebooked on Austrian. What a joke!

love the crews and my only problem was the delay at Frankfurt was very bad. I have travelled with Lufthansa for over 30 years now and this was cost me some planned business appointment

The flight delay made the connection a bit tight but that's outside the flight crew's control.

We just made it to our connecting flight. A long, long speed walk!

We didn't get the coffee with breakfast in the morning.. 30 mins lazer I asked flight attendant why don't we get coffee now at least.. after the breakfast..she said that captain announced possible turbulences fee minutes ago, which didn't ecplain why we didn't get it with the breakfast..breakfast was very poor btw..just little pastry which you can eat in 4 little bites. Turbulences fortunately didn't even happen.. but we didn't get that more than necessary coffee in the morning after the night flight with very poor sleep.. They just served breakfast 1 hour afzer we took off..at like 11 PM.. that doesn't make sense at all.. Also, flight attendants weren't very nice..they looked like they're not happy with their job.. :/

Lufthansa still has a good level of quality compared to US airlines, especially with respect to (1) food quality - actually tasty, (2) good French red wine - free, (3) good movie selection. Also my ticket price includes 1 free check-in luggage, while some other budget airlines sneak in an extra $150 for a checkin.

I think they overbooked Frankfurt to New York and bumped me off. This changed my return travel I arrived home about 4 hours late. Almost 24 total travel time Totally unacceptable Would not travel with United

We were moved twice on flights to the point we weren’t even on Lufthansa anymore. We had to fly united. Lost paid extra leg room twice. To top it all off we’re forced to pay $375 and $275, respectively for you luggage that was considered sports luggage. We were told it would be Lufthansa fares l, from the united desk, AND WE DIDN'T EVEN HAVE A LUFTHANSA FLIGHT! I’ll be calling once my trip is over on October 7th to all airlines and Kayak. This was ridiculous!

Everything went smoothly and the staff was very kind. I’m glad I purchased the extra leg room for my long flight; it was totally worth it. We were served 2 meals for a 9 hour flight which I was not expecting and they were very tasty. I appreciated them being vegetarian. Customs line in Munich was long; I had a choice to have a 1 hr 40 min layover or 2 hr 40 min layover; I took the longer layover which I was thankful for because my flight was delayed 30 minutes and there’s a good chance I would have missed my connecting flight. This was my very first international flight and I would fly Discover again without hesitation. Thank you for taking good care of me!

I liked everything BUT the temperature. It was freezing and now I am sick.

I liked Quiet people around me. Crew could have helped people with overhead luggage so they aren't moving other peoples bags around and causing problems for people that had there bags there first
