Pros: "We finally got here."
Cons: "Communication about the delay , which gate we were leaving from, having an entertainment system that worked (they said I could use my device with the app downloaded, but it did not work, I kept getting an error)."

Pros: "Not much crew stayed in back almost the whole 6 1/2 hr flight and seemed not to friendly"
Cons: "It would have been better if they had departed when they said they were going to after a delay. Flight was delayed first 1 hr then two more hours. The airline finally posted that it would depart a 4 PM and we didn't even start boarding until 5PM. Then they tried to rush us on so that everyone was standing on the HOT jetway for 10 min waiting to get on the plane. Plane didn't take off til 5:35 PM. Over all on this trip I had three flights that were delayed. I'll think twice before taking American Air again."

Cons: "Left on time and arrived early:)"

Pros: "New plane"
Cons: "Boarding, no gate changes, no flight delays"

Cons: "Your staff needs to utilize better communication. I scheduled the first flight of the day, and it was delayed. We were stuck on the tarmac for an hour without anyone telling us what was going on. We had to return to the gate to refuel and we left at the time we were suppose to arrive to Charlotte."

Pros: "The inflight enternet selection was great, totally enjoyed it. Crew service was good and kept us updated as we approached Charlotte."
Cons: "Gate C19 was hot and didn’t have adequate seating for passengers in the area"

Cons: "Nothing the flight was great and very fast."

Cons: "It ridiculous how small the seats and aisles are. It not fun flying any more"

Cons: "TSA"

Cons: "Entertainment is becoming too complicated for us old heads. Food, I still resent having to pay for something that is ed to be included in my fare."

Pros: "Quick flight. Took longer boarding than air time!"

Pros: "Must wider seats on this aircraft"
Cons: "Inflight monitor broken"

Pros: "Friendly staff and helpful"
Cons: "Did not fly out of Ontario, I was being led to fly out of LAX since there was a delay. Ended up flying out of John Wayne Airport."

Pros: "Several of the flight attendants were rude and obviously dislike their jobs. I had family scattered throughout the plane and we all had the same impression"

Pros: "great"

Cons: "On time"

Cons: "I didnt like that we were an hour and a half delayed and we werent informed why. Then as I am trying to update my pickup person one of the crew members was really rude and I tried to explain and it didnt help. She was rude infront of all the passengers. Not planning to fly in AA anymore."

Pros: "The flight was on time. It was smooth and we had absolutely no problems"

Pros: "I like the in-flight attendants as they are courteous even though it was late night flight. I cannot complain at all."
Cons: "Gate agent refused to try to put my 9-year-old son to sit next to me. She said "It's full flight" right out of the bat. Well, even if that's the fact of the matter, at least, be kind in responding to customer's inquiry. My son was seated across the isle, same row, but in reality the row was not even straight. And as a little boy, he cannot sleep straight and he has to lean to a stranger's shoulder? Thankfully I got a nice gent who should have sat next to him who were so kind to exchange seat with me. It's all in the attitude.... hopefully my attitude is not as bad :-) But maybe the gate agent was so tired for it was the last flight from ONT, at 1 AM. Bless her heart! Thank you though for your help to get the plane leave on time.!"

Pros: "We arrived safely."
Cons: "I don’t like having to pay for luggage or upgraded seats, WiFi. All money makers. Wish every airline could be like southwest."

Cons: "No real complaint of the flight or staff. Next time I will upgrade my seating."

Pros: "Easy and quick boarding. Excellwnt service in first class. Comfortable ride."
Cons: "Nothing. Excellent travel experience."

Pros: "seats are very uncomfortable I know they can make a plane with a wide enough aisle so that you don't get hit in the arm every time the cart or anyone goes past you. why can I ride a twin otter and not need a seat belt extender and need one on American? On the return on the Airbus, the seats were a little more comfortable, but still need seatbelt extender."

Cons: "The maintenance issue took 3 hours to confirm and then when flight was cancelled, there was no announcement over the loud speaker to tell us so we could line up for rebooking attempts. Then was a rush to try to get in right line to make next flights to connect through to Paris."

Pros: "Everything was great to me"
