Pros: "Smooth and easy."
Cons: "Not applicable"

Pros: "nothing other than on time departure Ann's arrival"
Cons: "I specifically shopped carriers other than delta or united, tho my regret usa carriers have stopped offering comforts, service, quality food. Not sure how, but even though I bought virgin Australia ticket and flight, I ended up on delta. Terrible sitting, even though after I paid for tickets I was charged extra for more leg room and priority boarding, I got neither, they advertised free texts in flight, it didn't work either."

Pros: "Requested a special meal over the phone when I checked in i.e. 24 hours before talk off, customer support confirmed my request but the crew told me that they had not received anything as such....crew didn't even bothered to offer any alternative. I was fine, didn't have any reservations but my wife and kid went starving all the way remember it was a 15 hour flight"
Cons: "Hospitality"

Pros: "Crew was excellent. Food above average. Plenty of entertainment options."
Cons: "Delta is not the only airline to have planes with the new seat configurations in First Class but they are a big disappointment for tall passengers and couples who enjoy traveling together and cannot even carry on a comfortable conversation on a 15-hour flight."

Pros: "It was on time"
Cons: "Too short of a layover in Atlanta"

Pros: "Crew were lovely, boarding wasn't too painful."
Cons: "Payed extra for a seat that was the seat I selected. Totally disappointed"

Pros: "on board service was nice and promptly"
Cons: "Delta continúes to use an older 757 in this 6-hour flight with cramped seats and seating arrangement in business class. I have taken this flight several times in the last 2 years and written about this issue but now doubt anybody cares about these comments. To make things worse, my seat would not recline!"

Pros: "Crew was stellar, very accommodating."
Cons: "Food was WAAAAY to salty. Needs some more flavor than just salt sad to say. Would be nice to be offered an entire can of soda not just a cup full of ice and a tiny amount of liquid. Charging for exit row swats? Cmon.... I'm 6 foot 5, why should a 5 foot 115lb woman get all the extra leg room but I canot?"

Cons: "1. Boarding order is not by seating making boarding very inefficient"

Cons: "I sat in a window seat and they put a 350 lb person in the center seat. For 3 hours I was squished against the wall. Flight attendants noticed but did nothing to reseat either of us."

Pros: "We travelled Economy comfort which has extra leg room & recline, which is great for a long flight such as this. Food was ok, crew were great & there was a lot of good entertainment to watch? A nice smooth ride down to Sydney."
Cons: "Food wasn't so great & coffee as with most Airlines is terrible."

Pros: "Arrived 30 min early."
Cons: "Loading"

Pros: "Crew was very nice and helpful"
Cons: "It would be really nice and good for the environment to utilize less plastic bags and find ways to recycle more. When I think of the amount of plastic used in every flight I cringe knowing where all that plastic would end up."

Pros: "So ridiculous airline didn’t though in costumer at all"
Cons: "Nathing"

Cons: "Debbie in Business Class made the trip even more special than ever! 1. Congratulated everyone on board for thanksgiving for those who follow that tradition 2. Spoke so kindly on the PA system in both English and fluent in Spanish 3. Kept my coffee hot fresh and always was smiling even those had to work on a holiday We will always fly AmericAn because of flight crew like Debbie..... 1000% super star for AA!!!"

Pros: "The crew was very nice and helped me with what I needed."

Pros: "cabin attendant was excellent"
Cons: "terrible plane because overhead space is extremely limited and the curvature of the plane limits legroom for window seats."

Pros: "My wife and I chose premium economy for the long flight from L.A. to Sydney. I believe it was well worth paying for the differential level of service."

Pros: "Seating had more space, the crew very relaxed and good humour as well as professionalism."
Cons: "Well the flight was short, so not much more could be done on this particular flight. The restroom could be a tad larger but think was on an older aircraft."

Cons: "It's a long time in an ever smaller seat"

Pros: "The boarding was fast."

Pros: "Upgraded to premium economy, nice seat, overall comfort."
Cons: "Leg rests for our seats didn’t work. Crew said ther was no fix for problem and left it at that. A bit disappointing. Fruit plate was disappointing, but pastry and yogurt was nice. Fruit wasn’t fresh."

Cons: "Crew serving food passed me by by, seemed rushed and missed my row."

Pros: "Good plane with excellent crew."
Cons: "Bulkhead seat in Main Cabin Extra was a nightmare. One has to be in cirque du soleil to navigate through breakfast in the extra small tray."

Pros: "We left a few minutes early"

Pros: "Love flying with AMERICAN AIRLINES."

Pros: "staff was very nice. boarding was on time and efficient"
Cons: "no screens to watch movies. the plane was delayed for a repair and we had to sit on the plane for two hours before we took off. they should of let us off the plane during this time. because of this the flight felt longer. there was no choice of movie because there was only the screen in the isle. the food was horrible for dinner. the smell made me feel sick and the taste was worse. a sandwich might of been better than that disgusting hot food."

Pros: "They boarded quickly, left early, arrived 40 minutes ahead of schedule. The staff were very friendly and efficient."

Pros: "The trip was easy and the time very good set!"

Pros: "That our pilot was giving us updates as to why we were slightly delayed."
Cons: "Our flight attendant didn’t know what food we were getting. When someone asked in front of me, she said “I’m not sure it could be either turkey or ham”. If you serve customers from all walks of life including Hindus, vegetarians, Islam, Judaism, it should be expected that the flight attendant know if that is turkey or ham. Another thing is that there was no final check by the flight attendant. We landed with tray tables down, seats recline, and people were still on their laptops."

Pros: "The entertainment"

Pros: "The premium economy service was well worth the extra money. The crew was attentive but not annoying on an overnight service. The food was much better than other long haul internationals. And we arrived rested ready to see the city"
Cons: "Again boarding was just a mush of people. American keeps revising the boarding process but does little to make it actually efficient and orderly. The grouping should have made things better but gate agents don’t consistently reinforce the policy so passengers are all lax."

Pros: "The airplane is new"
Cons: "The crew was terrible, so rude, really I don’t understand why there are like that. Is like asking a favor for everything . The seat are to short of space and uncorfortable"

Pros: "At least they should give a can of the soda"
Cons: "The cookie"

Cons: "The seats are much too small both width and length wise."

Cons: "Food in general"

Pros: "Friendliness of gate staff"
Cons: "Nothing"

Pros: "The flight left on time. Pleasant crew."
Cons: "As usual, the seats for a 6'4" guy are not good."

Pros: "It was nice that plane wasn't full so I had an empty seat next to me. Crew was nice."
Cons: "AA trying to sell seat "upgrades" during online checking."

Cons: "Delayed!!"

Pros: "It was quick and easy."

Pros: "Everyone was quick"
Cons: "Small seats"

Pros: "Ss"
Cons: "Sd"

Pros: "the crew and the people at the desk for boarding were great. the app helped me keep up with the changes"
Cons: "delays and changing gates"

Pros: "It got us there on time"
Cons: "No inflight entertainment on the longer flight. Uhgggg."

Pros: "Spacious seats, excellent service and the food was great for an aeroplane meal. Lots of bathrooms and I was always able to access food and water."
Cons: "They still use the dual port for headphones for the entertainment system so you are unable to use your own headphones. I didn't watch anything because of this."

Cons: "The time it took"

Cons: "On my flight from San Jose to Arizona there were no t.v , so it made for a painful five hour flight."

Pros: "On time"
Cons: "Lot of movement"

Cons: "AA has the same shuttle problem at DCA."

Pros: "only the low fare; which wasn't worth the experience we endured. i do not plan to use them again!"
Cons: "that was much too long a flight to be to be put through such an inferior"

Pros: "The airline was excellent, I am over being cramped in these planes for long flights. Unfortunately living in Australia makes us have to do the long flights."
Cons: "When you are travelling on long flights travelling all night, people in front have seat reclined right back and it is so hard to get out when you need to go to toilet."

Pros: "I have been traveling several times with this airline and think they are good overall."
Cons: "Reclining chair sometime is not working."

Pros: "crew was good"

Pros: "Excellent customer service. Good food."
Cons: "Didn't realize that codeshare meant operation by another airline, so we waited in line to up at the wrong counter, in the wrong terminal and then had to schlep our baggage to the right one. Good thing we were early."
