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

Business seating is soooo uncomfortable. You can sit straight up or lay down. You need pillows behind you because the back doesn’t lay down. Those are need to “prop” you up. The chair has no padding whatsoever. Food was gross. I’ve eaten on Finnair before and the food was exceptional. This time it gave 2 people in our party diarrhea. It was the chicken dish. I took 2 bites and didn’t eat anything more. The flight attendants were nice. You needed an additional lounge in Terminal D at DFW Airport. After waiting 40 minutes to enter, we finally gave up and went to a bar across from the club doors. I’m unsure if I’ll ever book a Finnair flight again.

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.

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.

The wheelchair service is useless. They live you in different spots, not tell you anything just wait. I waited 30 minutes in Frankfurt when decided to walk the 25 minutes distance. In Budapest nobody came.

It was perfect! I've never flown with United before, but I definitely will in the future

I had a cancelled flight because of technical issues going to my destination, and a delayed flight coming home. All told it wasn’t a total bust.

Just a bad day to fly. Flight was delayed from scheduled 6:50 pm departure to 8:50 pm. Combination of factors mostly related to weather at the destination airport (which is where the incoming flight originated) which delayed the inbound flight over an hour. Once on board, we taxied but had to hold again on the taxiway for 10 minutes or so. We did not get wheels up until after 9 pm. The flight was smooth but about 18 minutes from our destination, we had to hold for several minutes more due to weather at ORD. We finally landed at ORD about 11:08 pm (accounting for the time difference, that was about a 3 hour delay from our scheduled departure time). It felt like we were never going to get to our destination. But the flight crew and attendants were very good. The movie selection onboard was also very nice. Got to watch half of a movie just during our taxi from the gate at ATL due to the delay!

Fine. The issues I had were associated with luggage being delayed from Turkey to Tanzania

No meal service to the back of the plane as it started late or was too slow to get it out before it was time to land.

Terrible, if possible won't be flying again anytime soon!

Efficient boarding and early departure. Very smooth flight. Early arrival in ATL. Great flight.

We purchase first class seats for the first time for multiples of standard economy ticket. There was no access to the club lounge and no priority boarding. The meal and the service once on the plane were superior and the seat was nicer, but not worth the price difference. I will be happy to seat in economy and spend the difference on more travel.

The business class seat is exceptional. I wish the food is more palatable.

Plane was super cold. No entertainment unless you were with mileage program Getting off the plane was super slow

I appreciate that I finally got the seat I paid extra for this time. Thank you

Half of the TSA checkpoints at PHL are closed. Also, there is no standby for first class passengers. You can only standby for coach. Very dated policy and inconsistent with peers.

It would have been nice if American tried to care.

Delayed initially because they couldn’t print the flight details. Poor instruction on delay. When I got on the plane the flight attendant argued with me about whether my carry on would fit (it did, although she didn’t acknowledge that). No greeting (other than arguing with me) getting on or off the plane.

Beverage service was not good. Also just one service in 5 hr 30 min flight. No ask fir water ir anything beside one time beverage service.

They are always late and seats was also not having working charger

Broke my luggage and I can't get a resolution yet.

My flight to London from Philadelphia was cancelled due to weather.

This flight captain and crew were amazing, started ahead of time of departure and reached 30 mins before arrival time. Amazing!

Awful. They didn't even show concern that her connecting flight( Dallas to Mardrid) was gone/missing. I don't understand how that is even possible. Rudest answer from one of the crew was that American Airlines sold the tickets to somebody else. My daughter was not in the list.

The flight was canceled on a Thursday last minute. I lost thousands of dollars in hotels and car rental

Excellent lie flat seat for premium economy! Great staff. Bad food . Not so great entertainment. My bag didn’t make it either.

Really like the idea experience on this airline I will use again

The pilot was professional and very good. The flight crew, very young and often looked flustered and overwhelmed. The seats were among the most uncomfortable in the air. The boarding somewhat chaotic. The price reasonable. Overall it was an average budget airline experience...although Iberia is not a budget airline. I fear if Iberia doesn't up it's game customers like us will go elsewhere.

It wasn’t great because the third-party from Kayak there was just no information about how to check in with Vueling. And the purchase of the ticket from under pricer just made everything really difficult. I’m unlikely to use Kayak again for these reasons.

the seats were so cramped you could barely move. it was difficult to eat when passengers would recline their seats. the seats were so flimsy and unstable that whenever someone got in and out of their seat, it bounced like a spring back in your face. the movies were nice. the food was terrible. even though the conditions were terrible, they tried to pressure passengers to relocate their seats to accommodate adults who were related and wanted to sit next to each other, even after the passengers expressed that they did not want to move for that purpose. on the connecting flight, the “service” consisted of items for purchase. even though the flight was only 45 minutes, once again passengers (including me) were pressured to relocate for people to sit next to each other. they couldn’t be apart for 45 minutes? this was much less compelling than being apart for an 8 hour flight.

Everything went smoothly, and we even arrived 40min earlier than scheduled, on an Orland-Madrid route.

It was budget airline Veuling, even though we booked Iberia.

The staff was very nice and helpful. Some of the best crew I have met.

The gate agent made me check my carry-on in Denver, even though I've traveled all over taking this case on the plane. Beware folks. Food in Premium Economy was quite good - excellent blanket! Flight attendants on the Heathrow-to-Budapest flight on 3-27-2026 were quite snappy. I got a frown when asked to unscrew the water bottle cap for me (I had a cast on my right arm). Also woke up right when they were handing out biscuits. She had given my rowmates one and was in the process of giving water when I asked for a biscuit. She scolded me and said, "You snooze, you lose". She did give me one, but I thought that comment was uncalled for.

Wish the food and overall service was better. They treat Business class passengers same as economy

Food options limited and quality wasn’t very good. I was I was in premium economy and the people in front of me pushed their seats back to fully reclined position which made it difficult for me. My seat wouldn’t recline at all. I suggest that BA restrict the recliner more. Also, the audio in my headset didn’t work unless I held it in all the time. Entertainment choices were good. Customer services is excellent. Thank you to BA team.

WiFi wasn’t available to economy until the end of the flight.

Very good staff members with sincere passion and responsibility in their job.

We paid for Business Class seats, but system did not have us and they were not available.

Very please with the seating that the Kayak staff booked for us!

The luggage problem I previously mentioned was actually this flight

Late. And service was very slow - passengers sat for well over an hour with dirty trays etc surrounding them

Getting the boarding passes between the BA and AA apps was very clunky.
