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.

The seats are very uncomfortable. They never have tomato juice. Usually late

Finnair was not able to get our luggage on a connecting flight and there was a substantial delay of two days to obtain our lugguage. They did not communicate well, and we had to travel a significant distance to finally get our luggage. It has been a very negative experience.

Comfort. Not good very little space after the person in front of you lay back.

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.

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.

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.

The plane was warm and stuffy. The crew was friendly but got 2 orders wrong. I asked for sparkling water and wine with dinner and got neither. I asked for black coffee with breakfast and got coffee with cream. Service was so slow on my side of the plane they ran out of 2 of the 3 desserts at dinner and I was in row 12.

It was terribly delayed with zero support from united airlines. I reached at 1 am in the night. They did not provide any option to change the flights.

Flight cancelled instead of leaving Friday am now, maybe, leaving Sunday

one of the flight attendants on the Dallas to frankfurt leg was somewhat rude..

Friendliest Flight Attendant I’ve seen since I flew on Southwest Airlines. The whole trip was outstanding…and arrived Early!

A little bit more leg room in premium economy. I am 6’4”.

Sucks ! All three flights I was on this trip were delayed.

When I got our tickets, my husband and I were easily able to get seats together (including a window seat). When we checked in at the airport all the seats were reset and we had to pick new ones, so we couldn’t sit together because there were only middle seats! Ugh that’s the worst. We were back so far we had to check our carry ons which was annoying because I bring an expensive camera that I don’t/cant check so I had to reorganize my items. Once we were seated on the plane we had to wait an hour to take off and they said there was some weather/air traffic in Denver but it was unclear. The lady I sat next to complained that our seats didn’t go back and we both got free complimentary snack boxes which were quite good. I wasn’t going to say anything about the seats, they were the typical uncomfortable kind. It would have been fine if the 2 hr flight hadn’t turned into 3 hrs. Not the best flight but also not the worst.

Food wasn’t very good, old business seating configuration on an old A340

Crew is way too many times on the intercom re explaining the same thing

Nothing. I flew business class. I always try to avoid air Canada because it’s the worst airline and it’s proven on international level. Sad and embarrassing…

The flight was delayed and was not forthright on the time that it was likely to depart where Flight Radar 24 was reflecting a later time that ended up being accurate for the takeoff. The plane was filthy with food smashed into the carpet and crumbs were piled under the seat where I was to put my backpack. It looked like a full sized Lotus Biscoff cookie was pulverized under the seats in my section. The seats were so uncomfortable especially when the person in front reclined his seat completely to where it was smashed against my knees and I am only 5'2". The fruit and cheese box for $13 was lackluster with no flavor and not satiating at all. The plus side is that I did get one full can of ginger ale. The flight attendants looked miserable and tired, probably due to the last minute need for a new flight attendant to fill in since the original one assigned could not continue on to service this flight. Improve the flight experience for customers and maybe the irritability and stress of flying in today's environment will not negatively impact the joy and stress of the employees/flight crew. This is why I prefer to fly non-US carriers whenever given the chance.

The big challenge here was that the inbound flight was delayed, THEN, the aircraft was deemed in need of service, so we had to deplane after being a few minutes away from departure, THEN we had to switch terminals, where another plane in our gate had maintenance issues so we had to change gates again. I am a regular flyer (not on American) so I understand these things happen. The crew was great. The pilot in particular was gracious and understanding and stayed with the passengers the whole time to answer questions and give updates - that was impressive. But the flight was massively delayed as a result, and today I really wanted to be home in time. Sigh The flight was otherwise great.

My original flight kept getting postponed multiple times, I would have missed my international flight if I waited. It was postponed through the next day. I ended up having to drive 3 hours away to get my next flight.

DFW notification of changing the gate notice was an inconvenience.

Mechanical issues and delays. I get it but bad experience. Turned my 3 hour airport experience into a 9 hours

The flight was delayed multiple times due to the inbound flight arriving late, which is not a major issue. That being said, the boarding process was awful. The gate agent(s) didn't allow sufficient time for the pre-boarding passengers to get settled in and then called the four priority groups at the same time - i.e., called Group 1 and then called Groups 2-4 all at the same time. This approach had all four priority groups standing on the jet bridge from the airplane door to the gate end of the jetway for 10+ minutes in the heat (i.e., it was 96F outside and uncomfortably warm). This approach also made the actual boarding process a mess. There were multiple points of failure with the boarding process that turned a late departure into more of an issue.

Worst experience ever, extremely disorganized airline with super rude crew for first class passengers. I have submitted feedback to AA customer care online that this was my worst experience traveling in over 30 years

My flight attendant was miserable. Bathroom filthy and the water soapy in the tea. I’d choose delta everytime.

Nothing with the flight. It was good. Crew as very helpful especially fist class flight attendant.

I am generally an American Airlines loyalist but this flight was not good. I was seated in an aisle seat and the gentleman in front of my had his seat fully reclined which made it impossible to work on my laptop, eat or drink.. The gentleman in the middle seat was watching something on his phone without headphones.

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.

We departed late but made up most of the time in flight. Our ticket was pure economy, so it wasn’t anything fancy; however, I heard that we arrived in Madrid at the exact same time that First Class passengers arrived! Overall, our experience was similar to what we had on other American Airlines transatlantic flights - good value at a reasonable price. We were even able to get our carry-on baggage onto the plane without needing to gate check it.

The crew were not very personable. The crew did not serve tea or coffee. The bathroom was not kept clean. Two out of the 5 toilets in the cabin weren't working.

I described my experience in the previous window. I didn't realize that there would be another opportunity for this flight. Please look at my response in the previous window.

Boarding was 2 1/2 late no explanation Captain said he did not know why, but he rested at home for an extra couple of hours. Food was edible, Nothing more.

The flight was delayed twice. When the crew explained about the debris causing flat tires, I was glad they took the time to change all four.

The airline refused to board me because I showed up only 50 minutes prior to departure time, despite the fact that shortly before that, when I arrived at the airport still in time, they changed the terminal and I had to take a bus that took 20 minutes. Keep in mind that for some maintenance error I could not check in online like I usually do. Personnel at the airport was unable to let me in, customer care was beyond useless, the original airline operator (Iberia) was as useless as a toilet paper roll core in time of a wipe and all this uselessness made me waste my ticket, my reservations, my long time parking, food and most of all the joy of being with my family for the new year after working my bottom off even at Christmas. Am I happy? Come and ask me in person!

The food was horrible. The crew skipped over me for drinks(only got food?). I had to wait until everyone else was served drinks in order to receive mine(meal was done). No earphones were given. No free WiFi.

WILL NEVER FLY AMERICAN AIRLINES EVER AGAIN A TRUE DISGRACE

Yeah you have time and can sit around for a while to be okay for you but if you planned on getting connected flights I recommend not to fly with this Airline it's best they for flying out of the country

we originally had premium economy seats when we booked, but because we were forced to re-book because the first leg of our journey was delayed for several hours, we had to fly economy. Less room, less comfortable.

All crew except 1 were excellent. When I asked assistance with business class seat conversion to a bed (not being familiar as never used before but have numerous times with other airlines) crew member helped very reluctantly. I should have told her that business class seat conversion is totally different in each airline such as Delta, New Zealand Air and United. Sorry it was my 1st time with America Airlines. Now I know, I won't bother asking assistance in future.

Late! Late and late! More than 1hr 30mn. This sucks when it is the last of a 4 flight journey. I missed my dinner! Which is not nice on Valentine’s Day!!! But better than the gate next to us, the poor Chinese people were rebooked to the next day flight. AA had to call security as it became very heated with the passengers! It was a mess at DFW that afternoon/evening. I wish they had some food for the people who travel as part of international journey. Indigo does it in India and it is fantastic.

My enetertainmnet screen was broken. Lost my bags. Almost missed my flight do to connection issues with (despite a request) ZERO help from crew. Food was edible. Potatoes pretty good even

Didn’t fly with them as someone had cancelled my flight

We were never able to take this flight because our first flight from Austin to Dallas was cancelled.

The internet was horrible. Plus they charged me $25 for service that didn't work which should have been free since I'm Concierge Key. The flight attendant Rick Young was excellent. Greeted me by name and very attentive.

Boarding in Dallas was hell with extremely rude gate agents , especially a lady named Rajathi who was the epitome of rudeness with no compassion at all . She was horrible and I wonder why airlines have people like her on their roster who exude arrogance and haughtiness . Will probably not fly British Airwsys because of people like her .

All and it was good . But no one woke me when meals came around . Please have a don’t not disturb sign if you opted for that . Left very hungry missing all meals .

They ran out of earphones so my 3rd daughter couldn’t use the on board entertainment the entire flight. They also ran out of food choices (chicken or cheese) by the time they got to the last few rows, so my oldest daughter, wasn’t given a choice. Luckily she isn’t a vegetarian because they only had chicken left.
