Finnair was ok. But some things were pretty bad: 1. Crew was not friendly, especially a crew member named, Maria. She woke me up while I was deep asleep by force just to let me know that 2 people can’t be on the same seat (my toddler and me) for sleeping. 2. There was no vegetarian option in the menu so I had to eat bread for one meal 3. They didn’t have an option for child meal

The food was delicious. There has been a major improvement here in the last few years. Excellent, friendly service. An enjoyable experience.

Awful. Delayed for unknown reason. Boarded late, part of a Tight connection ands had to go through customs and immigration. And they lost my bags.

Late, dirty cabin, charging ports broken, uncomfortable, no tomato juice, barely edible food

Flight on time, landed well ahead of schedule. Attendants were excellent and responsive

The crew was friendly, and the flight landed on time

Rude Iberia security crew at the Madrid terminal. No Iberia officials to be found to redress complaints at the gate. No supervisors. Nothing for processing upgrades at the gate Iberia app did not work to let me upgrade my options to higher classes. No water was offered on a hot day in Madrid. Madrid airport air conditioning was so weak that people were sweating. Never book on any airlines that codeshare with Iberia.

Great if not for the boarding by bus at Heathrow terminal 3. Medieval disappointing time-consuming and very hard on handicapped flyers. It was awful

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.

It was listed on my ticket as Finnair but there was no indication that the flight was Finnair. In fact the number was even different. There were no employees there until exactly 2 hours before so we had to wait in line at Iberia and hope

Very disappointing that on an international business class flight they would not give me access to the lounge in Boston. They said it was because it was a codeshare flight. International business class should include lounge access regardless of codeshare.

The counter person at the gate was rude and demeaning, to the point that I wouldn't fly this airline again.

Crew was great. Seats are cramped and uncomfortable and I’m a small person.

Awful. Delay after delay. And then again on the tarmac.

Kept changing the takeoff time and the moved it up so arrived when boarding had already started. Then sat waiting to taxi in for a long time

Food was not Good Nuts came very wet & not tasting Good Main course I asked for Steak they got me Chicken because they don’t have more !!!!

It cancelled and we were unable to catch our connecting international flights.

Leaving at 7 when scheduled to leave at 4:20 - you tell me. Understood there was a ground stop. Then having to "reboot" the plane because of a lighting strike, also understood. But basically the flight was a "clusterf#$%".

On boarding crew at the airport called in the boarding numbers too early meaning before the previous line was completed resulting in later numbers getting to board ahead. Also she asked those who boarded from number 3 to have the tags in their carry-on bags and leave it in the jet bridge. Most of the overhead bins were empty though. This is more work for the ground staff in addition to more inconvenience for passengers waiting to get their carry-ons from the jet bridge.

ok, butt flght was delyed for 2,5h from Frankfurt, and next Flight to Columbuse same

The flight itself was excellent, but getting to the plane was literally an exercise in pain. My wife needs a wheelchair and can only stand/walk for short periods before having extreme pain. We had to take a bus to a loading platform and use a terrible elevator to get up to the plane. Meanwhile the rest of the bus were using the stairs. This meant the people who needed to sit down were stuck standing at the end of the line while everyone else boarded. My wife was in agony.

It was amazing. I sat in First Class as a Saga Premium member, and my service was top notch. It was wonderful. I only recently joined Saga Club since I do travel to Scandinavia often and enjoy flying through Reykjavik on Iceland Air versus other ways of travelling to Europe. This was my first trip sitting in first class, which I honestly wasn’t expecting!

There were no places to sit at the gate. Most people had to sit on the floor or stand waiting for the gate to open and board. We were told we needed passport and the person hardly looked at them. Maybe for 2 seconds. No announcement made asking to board by row or group. On a 5.5 hour flight the crew only came through the cabin 2 times offering water and buy everything else. For the price of the ticket at least offer free soda! The airliner was very comfortable

Crew was wonderful. I knew going in that the seats were not lie-flat in business class, but they reclined less than I expected. To save on waste, you have to ask for which pieces of the amenity kit you are interested in, which they will gladly give to you. Flight was fairly short, so no issues. I did have one piece of luggage not show up at terminal on landing. They were great about looking for it. Found it...it actually did make the flight and was listed as "not picked up" (?????--we stayed over an hour looking for it, including in the odd-sized baggage claim.) Since "not picked up" they will not ship to my house and I have to go back to airport, which is in another town. I probably could have pressed this issue, but headed back to airport for another flight anyway, so will pick up then.

It didn't happen. Icelandair cancelled the flight from Nuuk, Greenland to Reykjavik, Iceland so I couldn't fly to Portland. Additionally Icelandair rebooked me on a flight that got cancelled too.

How can the airline deploy the oldest 757-200 with a broken down entertainment system and no WiFi for a cross Atlantic 7:50 hr torture chamber experience?? My seat 3A couldn’t be reclined. The footrest was flimsy and useless. And there’s no leg support unlike their newer 737-Max which they lavish on intra-Europe routes. Shame!!

At least one soda free, felt like I was nickeled to death.

Comfort of seats is not good. Like sitting on a rock for 6 hours. Also no in flight food and limited beverages unless you pay is not nice. Need flight to be dark during the “night” but attendants don’t ask for shades to be lowered..

Good. Lacking overhead bin space. No food offered but you can order online or in flight and pay for snacks.

We had to be bussed to the plane. And it was raining. Not a pleasant experience.
