Pros: "The crew was nice"
Cons: "boarding and unloading are nightmares. They really should load the planes back to front and if someone has a connecting flight, they should be allowed to unload first."

Pros: "The seating, the comfort, the entertainment, the complimentary food, the drinks. Everything was great with American Airlines."
Cons: "Nothing."

Cons: "The sound didn't work on my entire row for the in flight entertainment; it made for a long flight."

Cons: "Flight was delayed. Sometimes it’s not airlines fault. Not 100% clear on who was at fault. Toilets apparently water wasn’t working on aircraft. Upon landing at BNA a baggage guy attempted to rush us because flight was late and needed to get back to ORD. With no consideration for over 2hrs waiting"

Cons: "Commuter jet boarding at DCA is going to stink until the new terminal is completed. Just is."

Cons: "Not sure why it was a Finn-Air flight when it was an AA plane and crew?"

Cons: "Nothing"

Pros: "Crew very friendly couldn't be more helpful. Food snacks and drinks good. Very efficient boarding system the best I've encountered."
Cons: "Roof mounted tvs a bit disappointing and the films were just repeated. Coffee needs coffee in the cup, it was just milk and water no taste of coffee."

Pros: "Smooth boarding, the crew was really nice (and it didn't hurt that they were generous with the wine)."

Pros: "Loved all the meals. Tasty, well-coordinated."

Pros: "on time, quiet trip, lots of entertainment to chose from. if you like to eat and get alot of beverages you'll love this flight"
Cons: "had to do pre-clearance security screening before getting to the states and no notice given. This takes twice as long and if you don't get to the gate by a certain time you don't get to your flight. Thankfully we were at the airport 2.5 hours early and it saved us!!"

Pros: "Staff was great. choice of food/beverages."
Cons: "The people in front of us were having a party all night during the quiet period."

Pros: "Movies and did not feel squished. Never had so much food service on a flight before."
Cons: "Nothing negative to say."

Pros: "On time, efficient, new plane. No troubles."

Pros: "New plane, all kinds of entertainment choices including new movies, great flight crew, smooth flight."
Cons: "American check in software was down when we got to the airport. Created a very large line. Did not delay boarding, even though passengers still had to go through customs before reaching the departure gates. Had a bit of jog to make sure I was able to get on the plane."

Cons: "The Video on Demand service for movies, TV, and Music would skip every 10 to 20 seconds, jumping forward about 2 or 3 seconds at a time...making videos unwatchable. This was a problem for my seat, the two in front of me, and apparently many other seats on the flight."

Pros: "Lots of movies. Constant trash collection and drink service"
Cons: "Uncomfortable seats. Dirty bathrooms."

Pros: "We appreciated that American Airlines found us two seats together for the long Dublin-Chicago leg of our journey."

Pros: "Food was good as were the movies & seat"
Cons: "Gate supervisor (male) in Dublin was unhelpful. He announced theee times that the US Customes pre-clearance would close shortly. This announcement was in the gate area where everyone had already had to have cleared the Preclearance US Customs. Then when he announced boarding for priority and Business class he "pointedly" told the zones 1 thru 4 to all begin boarding at once (w/ one agent while three agents stood behind chatting) and to only use the one Priority lane. Thirty people all gathered for the very slow process. The Gate Supervisor the says he would start boarding Zones 5 and 6 in the other lane. Zones 5 & 6 all boarded while I (zone 1 passenger) and five others were still in que boarding thru the priority lane. Poor leadership. The Business Class flight attendant while serving snack, spilled my hot tea on my shirt, trousers and iPad. She was very apologetic and said that she wished she had not filled the cup so full. The tea "happens" and was no big deal. The Gate agent on the microphone in Dublin was having a bad morning and transferred his unhappyness to me, which I did not bargain for on the 27th."

Pros: "Nothing it did not exist"
Cons: "You cancelled my flight without telling me"

Pros: "Fast and early"
Cons: "Tv screens kept freezing"

Cons: "At least one of the entertainment systems wasn't working right. Otherwise everything was okay."

Pros: "Nothing"
Cons: "Miserable food. Just horrible quality. Truly - and I'm not picky."

Pros: "Friendly crew made a long international flight with a 14 month old as pleasant as possible."

Pros: "Little"
Cons: "Mechanical issues, late late late, bad communication, no apologies or compensation for huge waste of time."

Pros: "I wish I could remember the names of our flight attendants- but they were wonderful and really took time to get to know passengers! They were so friendly and went above and beyond in any of our requests. Loved them!"
Cons: "It would have been nice to have individual screens for such a long flight, but I wouldn't say that's a complaint. The flight was fine."

Pros: "Everything! Leg room"
Cons: "The touch screen for entertainment was maddening!"

Cons: "Completely ignored for beverage service"

Cons: "Poor communication Delays -3 hrs"

Cons: "Planes too old"

Pros: "ON TIME!!!!! Nice folks, smooth and safe."
Cons: "Got through the extensive security lines to USA one hour before scheduled departure and looked at the screen which said 'final boarding' which was not true and made us panic a bit, running for the gate. It did board and leave on time but not an hour early. This flight was night and day different than our ORD to Dublin flight of 5.12.17 which was 5 hours delayed and do stressful."

Pros: "Nice crew. Chairs were comfortable."
Cons: "Not enough movies! No individual screens. Plans had dirt stuck all along the air vents"

Pros: "The flight attendants were excellent."
Cons: "Wish the plane had been equipped with personal entertainment screens on the seatbacks."

Cons: "Lousy food. Cramped seats, try to make you pay extra for seats to sit together,"

Pros: "Good food-ample space"
Cons: "Tv didnt work for 3+ hours took 4 attendants to restart it."

Pros: "On time"
Cons: "No gluten free food available"

Pros: "The crew was great!"
Cons: "No leg room, tight."

Pros: "Getting there safe and sound"
Cons: "We didn't fly FinAir, it was American Airlines"

Pros: "Got an economy extra seat without upgrading, had a variety of snacks and service extras which were nice"
Cons: "Was never asked for dietary restrictions so no vegetarian meals were available, pretty old aircraft to be flying that route, no seat back entertainment"

Pros: "The movie selection and how often we were given beverages."
Cons: "I was selected for a random inspection. I was pulled aside and went through a separate check in process. I completed everything I was instructed to do and as I'm boarding, I'm pulled aside and told I needed to go back to pre clearance because someone forgot to punch a hole in my boarding pass. The stewardess and j had to run all the way back to security so I could go through the whole process again. I delayed the flight and everyone was upset. It was completely unnecessary. Simply because one employee didn't do their job, I delayed a transatlantic flight to Chicago. Best part, I arrived at the airport four hours before my flight. Also, the seats are incredibly uncomfortable. And I was separated from my traveling companion for this entire process. Had I missed the flight, she would never have known."

Cons: "The touch-screen entertainment system was not very responsive. It was difficult to get the screen to recognize your selection."

Cons: "Felt like an old domestic flight. No Wifi and screens in the center that are hard to see from the window seats."

Pros: "Individual screens worked well, food was good."
Cons: "Flight attendants with carts bumped my boyfriend's shoulder repeatedly, nearly every time they went by, without ever apologizing. They were also really rude when we asked for additional beverages. I travel very frequently, and I was shockedz"

Pros: "Available drinks"
Cons: "Poor selection and no coffee"

Cons: "No entertainment systems Chairs were old and uncomfortable"

Pros: "The captain and the flight attendants were very communicative and kept in touch with the cabin at regular intervals but not intrusive."
Cons: "There were 2 meal choices., one was chicken and one vegetarian curry/rice dish. Clearly the chicken would be the most sought after meal and the flight attendant even suggested the possibility that everyone would not get their first choice, and ofcourse they didn't. We had a group of 10 traveling and by the time some of,our group was served the chicken was gone. Our daughter was 7 months pregnant and was one who didn't get a chicken meal. I don't understand why the airline would not provide an adequate amount of meals that would apply to the masses. Only a few vegetarian to fill in for specific diets would be expected. We all felt this was poor planning on the part of the airline catering company.."

Pros: "Upon sitting down, I was able to fall asleep almost instantly. The helpful stewardesses were constantly aware of my needs."
Cons: "Check-in desk seemed confused and unorganized. Two very friendly ladies were helping out but were on different wavelengths."

Pros: "The food was very good! Chicken and mashed potatoes with broccoli was very tasty! A very small salad, a seeded bun, cheese and crackers and apple crumble rounded out the meal. Later pretzels and the grilled cheese and blueberry pastry. Pillow and blanket nice."
Cons: "Movies hard to hear with provided ear buds. I tried three and gave up."

Cons: "EXTREMELY LONG CHECK IN & SECURITY LINES"
