Will never fly American Airlines business class again. Medicore service and very old aircraft.

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.

I booked the flight with Finnair, which made the arrangements for downloading a boarding pass unnecessarily complicated. I wouldn't do that again. Instead I'd book direct with AA.

Helpful steward. Allowed me to move to some empty seats and I was able to get some sleep. He also had milk for my tea. Americans don’t realise that cream or half and half ruin tea.

My flight was on American Airlines, AA, through Finnair.. What I didn't like was that I couldn't get seat assigment until 48 hours in advance. I also was not given my AA Confirmation number. I called Finnair. They were very very helpful!

The last 3 hours it was freezing cold in row 56. Multiple people had their winter coats on and were utilizing the blankets provided by the airline. I also did not have easy access to figure out how to book my food allergy and advance for my meals. Most of everything I received was something I couldn't eat. This needs to be made more accessible. Also, I'm 5'10 which is the average height of the American male. I flew from Philadelphia to Toronto and then to Tokyo and the seats were absolutely unbearable. For that long of a flight it is impossible to get comfortable when doing anything. Flights need to have more space and stop prioritizing costs over people.

Was delayed at every point/ connection. Luggages missing for 5days. Had no medications for diabetes and high B/p. when bags where finally delivered on the 30th, the insulin and ozempic were no longer patent, as the ice pack had since dissolved and the authenticity of the med is now questionable, since they must be refrigerated. Please have them refund my bag fees. I should sue them for all the inconveniences caused to me.

Plane was packed but flew on-time, and the comfort level was great! All planes are a bit cramped, but the in flight entertainment was superb, snacks were nice, and the crew was polite. Got into Calgary on schedule...all we could ask for

I am very tall. All airline seats are a bit uncomfortable.

Lots of announcements that no wheeled carry on bags were allowed on the flight, yet the overhead bins were totally full and made it uncomfortable trying to get through and significantly held up departure. Why were they allowed on when they said that they weren't? Trash only came by soon after service and I wasn't ready to dispose of it. I had to first hold on to it and after flagging and attendant was told to stuff it in the seat back! I have never run into the need to walk outside in northern winter weather at an international airport and wasn't dressed to do so in the cold pouring rain! I'm not thinking that I'll be back unless I hear things have changed.

No complaints l will always do Air Canada once they are flying where I want to go

Flight was delayed an ultimately cancelled. Took me close to 45 mins with an Air Canada staff to be put on another flight.

Boarding was particularly poorly done with disregard for courtesy, professionalism, and efficiency. Think mid 70’s bus station.

My trip was ruined by the restrictions hidden in their "basic economy" plan. I'd flown hundreds of times and never encountered a program that does not allow changes of any kind. I don't know whose interface hid this information more, but I'm unlikely to use Kayak or Air Canada again after that experience.

Air Canada staff needs to be trained in hospitality. Most flight attendants are with attitude. Air Canada needs to carry additional food on board especially vegetarian plates as this category of travellers are on the rise. This is necessary for long distance flights. Blankets are cheap. Seats are not designed well Lower back portion should be thicker. Everytime thr passenger at the back of me took stuff or put stuff in the pocket of the seat in front of them which is my seat, I could feel them pushing or hitting on my chair.

It was a late flight; crew was invisible. Zero air flow - the tiny plane was a sauna; the left the lights on for 1/2 of the flight; there was no water. Never again.

What an amazing plane! We flew a 787 to Miami. Although the Internet was not functioning, it was a wonderful flight.

Plane was in good shape, multiple passes from the drink cart, and one of the smoothest flights I've had in a while.

Smell of jet fuel was overwhelming from inside the plane while on the ground at take off and landing. Gave me a sore throat and a headache. During boarding, de-planing, taxi-ing, waiting in line for take off, etc. Also, the vents didn't have enough cool air coming out (yes, off course I opened it all the way) so the whole flight was hot and stuffy. But just my vent - all the vents.

After lack of help in Philadelpha made us late to board our flight to akansas City, our flight to Kansas City was very good. And the flight attendants were also very good. The only thing that sucked was problems with assistance in Philadelphia caused our bags not to arrive.

AA needs to review it's policy whereby it's most tenured staff gets to pick their flights. This tends to place flight attendants with the most jaded customer service attitudes on long haul flights. Whilst I realize this is a generality I have experienced increasing levels of woefully poor customer service. One particular flight attendant on this flight was downright rude to several customers. After serving an awful meal they disappeared to their cots below deck and for the most part did not reappear until 1.5hrs before landing. A very disappointing flight.

Legroom was decent, but the seat comfort was horrible; I believe the seat cushions have lost their cushion. I was uncomfortable and had back pain throughout the nearly five-hour flight. WiFi did not work despite my attempts to get it up and running. This was very frustrating as passengers all around me were streaming football games, movies, and accessing email and text messages. One flight attendant suggested it was my seat, but that makes no sense, given WiFi doesn't work that way. On another note, I rarely have a good experience with aainflight.com.

Id like for them to not have lost my bag. And maybe be a little nicer to me, given the fact they lost my bag.

Seats are uncomfortable and my impressive barely 5’10” frame meant my knees were touching the seat in front of me. My 5’3” sweetheart found the seats equally uncomfortable The crew were transactional. The food edible. The entertainment manageable. The boarding process efficient. The experience okay.

Hey as long as you bring me back to earth in one piece I’m good! Otherwise great flight smooth take off and landing good staff Only thing is the staff at the back of the aircraft chatters a lot it’s annoying at times but I’ll let that go because they are very sweet overall.

We spent two hours on the plane before taking off due to a fault which I would have thought they would have found before boarding so we could have stayed in the airport. Water was in short supply so restricted due to the extra time and so hot. Vegetarian food was awful and wish I hadn’t ordered it and was left starving

Horrible, they detoured my first flight to Roswell and the communication on why was very poor, We arrive late then waited 20 minutes for them to set up the bridge. I arrived at my connecting flight gate and was told my seat had been given to someone else even though the flight was delayed. We then get to customer service and the computer went down for several hours. The person at the counter was eating their lunch while trying to help me get a flight. Dhe then rebooked on a flight with a connection that was leaving two hours prior to me landing. So I had to then stand in another line to get rebooked. I missed my trip to Morroco and waited 7 days to finally get my luggage. It was a nightmare.

Chairs do not recline. Finished the trip with an aching back.

I liked the comfort of the plane. It was unexpected from past experiences.

Chair is very high. Your feet cannot touch the ground for 8 hours flight. It was a nightmare. Food was bad.

Flight was delayed 3 hours and 15 minutes. The delay caused me to miss my tour group due to arriving late.

Flight boarded three hours late for no reason other than someone made a huge error in crew scheduling. We missed our connecting flight in Madrid and got zero help from American or Iberian airlines on rebooking. We had to pay for a car to take us to the Madrid train station and pay for train tickets to Santiago. We never used our booked flight to Santiago. American claims I can submit the expenses but they are not obligated to cover them. Very frustrating.

Super uncomfortable main cabin. Omg no leg space or seat space horrible

The trays weren’t wiped. They still had food from last passengers

Flight reservation was canceled withou notice had to spend the night in the airport

Check on was very hard. I believe my seats had been selected when I booked, but when I checked in I had to select seats. My previous pre assigned seats were no longer showing and I had to take seats I did not want. Check in took me forever. I also had to pay an additional 22/seat when I had already paid. Lastly thought I had pre paid for a checked bag., but that did not show up so I had to pay for a checked bag. 75.00????

Great until k found out they never got my check bags onto the plane.

Boarding process was chaotic. Confusion over Boarding gates: gate 55 or gate 56 ???. Unnecessary standing in long lines to board. Better to call out Boarding groups one at a time and everyone else to sit. Airline only has 2 Boarding groups 1-3 and 4-9. That causes over crowding and chaos

The flight was ok. The seats are so small. The free wifi for members was not an option on this flight. The one flight attendant, older woman with straight white/grey hair, was very rude. The gentleman next to me asked about the wifi since he was a member as well. He stated, accurately, that the option to enter the idea number was not available. Her response was, "I don't know what to tell you" and walked away from him. The rest of the staff was wonderful. I asked another flight attendant about the wifi, she said the free wifi was not enabled on that flight (true or not- at least she was friendly). It was also pretty dirty. When I opened the tray table it had mushed crumbs and there was a dirty used pair of ear buds in my seat pocket. Lastly the air vent above my head was working but stuck so I was unable to move it to face me when it got warm. I fly American often but this really was not a great flight.

Someone switched seats in business class so they could sit together and we were left apart (3). Very disappointing. Staff did nothing

I have always been pleased with their service. Would not change a thing

Three major things that led to my low rating, 1. Internet wasn't available for the whole time, and 2. TV became available way into flight, after numerous system reboots, and 3. Food is not good at all.

Did not use entertainment Food great Stewards had an attitude, not the best but below average from my other flights with AA or BA

They removed our booking without telling us. Cost us thousands to book last minute

My flight was late. We stayed in aircraft one hour 😩
