Austrian Airlines help and service was fine, but Kayak misled us into believing we had purchased a Business Class ticket. In fact, the tickets were only upgraded Coach Class tickets with luggage restrictions that belonged to the Coach Class. Very disappointed! Paid over $$$$ 9K for the two tickets. Very disappointing!

Austrian Airlines help and service was fine, but Kayak misled us into believing we had purchased a Business Class ticket. In fact, the tickets were only upgraded Coach Class tickets with luggage restrictions that belonged to the Coach Class. Very disappointed! Paid over $$$$ 9K for the two tickets. Very disappointing!

Quick and organized boarding process, friendly staff but not as many snacks and drinks as the previous flight overnight

Landing was a little hard. Food was not great My prior review was for the flight to nyc too

Five star experience all around except for my seat, which was broken. It would only go down 70%.Of the way. It defeats the purpose of buying a business class ticket if you don’t actually get to lay flat..

I love this airline.God bless CAO and the whole staff of this company

Great staff, efficient and knowledgeable. Very helpful with others and considerate towards those with children

WiFi would have been nice and some more powerful usb ports, available ports could not keep my phone’s charge much less charge the phone.

Not so good. I paid for a preference economic seat, and I couldn’t incline it back because it was blocked. They explained me that because is the last before emergency exit. The company new that but it was not explained in the seat selection

It was on time. Snacks could have been provided for free.

Tirana was crazy check in and getting bussed to another gate. Both Germany stops were intensive customs but organized, but that wasn't the airlines problem. The crews were fabulous on the planes. The announcements were not easy to understand in English, slurred speech. Customs inthe US were fast. We waited for luggage, three later arriving planes had their luggage and left before us

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.

Our experience on United Airlines was extremely poor. The plane was extremely cold throughout our entire flight- which multiple people complained about- and we had to wait 2 hours to get a blanket which was too thin and barely helped warm us up. As well as this, none of the entertainment features were working so we had to sit through a roughly 10 hour flight with nothing to keep our attention, including the actual flight path screen. It was an extremely disappointing experience and I would hope that this gets fixed if we ever choose United Airlines again.

United sent me a mileage plus number last year but that number is invalid so I can’t use it to check into flights or collect mileage. There is human to speak about the problem, only computers who keep asking me if I am using the correct email. It’s so frustrating and I cannot resolve it.

The woman gate agent in Phoenix was none too sympathetic about my check-in process as I am relatively new with using apps. I almost did not get on because she said I did not check-in. I thought I had via Kayak where I purchased a very expensive ticket. Lesson learned but to be told I may not get on as a matter of factly was difficult to hear.

Flight was on time. Boarding was smooth. Flight attendants were friendly and efficient. Entertainment system was broken for all passengers on the left side of the aisle. I would prefer if meals were not served on red eye flights. No one should need to dine at that time and it is disturbing for those passengers trying to sleep.

Gate agent did not hold flight for connection, provided no assistance to get new flight

I always appreciate when everything is on time! In this flight you have a short connection and it could be stressful , but is was easy and fast. They even ask people to wait so the ones that have a short connection could leave before. It was the fist time that something like this happened.

The plane pushed back from the gate on time. However, it stopped on the ramp, and we waited for over 20 minutes before the aircraft pulled back to the gate. Apparently, something of importance had to be removed from the aircraft by the gate agent. I found this to be odd. The delay was not significant, but I felt that whatever was on the aircraft that had to be taken off, should’ve been done before we pushed back from the gate.

Smooth boarding process. Early departure, smooth flight, early arrival. The entertainment package has very good recent movie options. The flight crew were friendly and professional.

My suitcase was destroyed. The top part where the handle is is completed broken. And unusable now.

Since when do I have to pay for my checked bag? I have a United Explorer mileage plus silver card and I was charged for my checked bags. This also is an international flight. So I would like an explanation to be clear before I choose an airline please?

Insulting. Lufthansa flight from Munich to EWR had us getting our luggage when we were told in Florence that it would follow us to Indianapolis. It did not. Then very slow security in EWR caused me and three other passengers from Lufthansa flight from Munich to miss the boarding closure. Behind me were two elderly grandparents and their ten year old grandson. We were all refused entry on a plane to Indy that was still at the gate. The doors had not even closed inside the terminal yet. No apologies or compensation offered. Not even a meal voucher let alone a free hotel stay for our inconvenience. I m not sure what the other three passengers behind me did ( they were elderly with a grandson, recall), but I stated 12 hours overnight in a chilly EWR airport until next flight to Indy at 850 next morning.

I was told in Florence my bag would go directly to Indianapolis. I had to wait to get it. Then security in EWR was slow so I missed my flight as United would not allow me on the plane even though it was still on the tarmac and the door to the tunnel was open. I blame both Lufthansa and United for refusing to allow me on board a plane that was clearly still on the tarmac. Behind me two grandparents and their ten year old grandson were on same flight from Munich to EWR. They were refused to board the United flight. So we had to sit for 12 hours in airport until next flight. No compensation has been offered either by Lufthansa or United.

Flight was delayed and luggage was delivered day after arrival. In Bilbao they told me day after would be delivered faster if I went to Bilbao to get my own bags so I did. Wasted my morning.

Seating was average for a first class seat. It very modern. I expected better.

very small seats screen did not work . I could not watch anything for 9 hours

The food that was served was superb!!! Awesome snacks!!! Frequent drink service!!! To me, this was shocking. I took a British Airways flight from Denver to London for the first leg of my trip and the food was horrendous. Thank you for keeping us fed and satiated on such a long flight!!!!

The seating arrangement by having privacy screens would have been more appealing. If you sit in the business class, you pay for extra comfort and privacy. Other than that, the service was excellent and the staff very professional.

The plane was late (as was my flight out from Birmingham the day before)

Best flight attendants ever! Very customer and service oriented, courteous, professional and helpful.

Flights were delayed but very last minute, also seats felt very squished on the second flight. Crew was very friendly and airplane was clean.

Excellent everywhere but Philly, the most rotten airport in the world.

Check in was not the greatest as had to talk to an agent to clarify things and then he transferred us to another agent who had difficulty processing my credit card as there was a system glitch and not a card error.

I was put into business class. Wow! My flight attendant was great! The food amazing’

Not so good with their baggage handling as they damaged one of my check in luggage

All went well on the flight, not happy of course with having to pay for a seat and in hold luggage of £50

We never made it onto this flight due to BA's lackluster organisation.

The air hostess were good, cheerful, but I didn't like the boarding. My son and I initially bought our flight tickets, making sure it included 1 luggage and a carry on. Tickets were purchased for British airlines, but we were merged with American Airlines. At checking in our languages, we were told, we don't have luggage prepaid so we had to pay extra $125 each and almost £60 on our way back. I think that's unfair.

Economy seats are so small and compacted so close together that comfort is negatively affected, especially on long flights. However that is due to aircraft design, not anything the airline can do about it.

3/4 bags delayed and 1/4 damaged at the other end. Flight was freezing

The crew were good. The flight was on time. The entertainment choice was ok. But the food was bad, tasted and texture were awful.
