Pros: "It was not crowded breakfast"
Cons: "Breakfast was lousy"

Pros: "very attentive steward, nice snack choices"
Cons: "they allowed too many late people to board after departure on a 100% full flight; not due to lines, but because they were late to the gate"

Pros: "On time departure, this flight tends to get delayed, not this time. Good service and pleasant flight."
Cons: "I prefer personal entertainment systems."

Pros: "The flight got me there"
Cons: "WiFi was too slow to be able to watch anything. Seat small and uncomfortable. Flight attendants not friendly."

Pros: "I appreciated that they were interested in the general welfare of the whole craft in the midst of storms."
Cons: "The long delays, the cancellation near midnight, the long lines to what I thought was going to be some type of reimbursement for all the inconvenience at now having to find lodging for the evening, spend an entire day back at the airport, and transport myself from the NEW airport they made available for me from the original airport I had chosen. Absolutely NO compensation or reimbursement due to "weather." While I understand they can't control the weather, this is literally one of the greatest elements in their company. They should have provisions FOR it. Running out of airlines I could trust and rely on, and thought American would deliver. But No, not even this one. Extremely disappointed and staying away from AA."

Pros: "everything but the cabin temperature. it was very hot and uncomfortable."
Cons: "Too warm in the cabin."

Pros: "Can’t say anything good"
Cons: "When boarding crew was rude because carry on did not fit the overhead compartment. No options to choose from for entertainment. Flight was delayed almost an hour while sitting in plane. Food options almost nonexistent"

Cons: "Very long time since I have being on s flight with tv in the aisle , and not on headrest .. this is s international flight ."

Pros: "It’s a jet"
Cons: "Boarding terrible at DCA, seats cramped"

Pros: "The crew was very friendly and accommodating. The food as usual just snack type food for purchase as expected. The entertainment system malfunctioned and we could not watch the movie they offered. However one flight attendant was very nice and gave my kids special cookies. Nice touch!"

Pros: "Short flight, nothing much to say."

Cons: "The food options on the brochure were not available, flight attendants had bad attitude and negative vibe"

Pros: "Mostly everyrhing"
Cons: "Food was so so"

Cons: "Just never enough leg room❗️"

Pros: "Flight attendants"
Cons: "Cramped beyond belief. Can’t roll carry on bags through aisles. Seems they’re more narrow. Boarding seems something beyond common sense. On domestic flights I only fly Southwest unless a must do trip and they don’t fly there. Our trip over to Milan on British Airways was wonderful. Sorry the last leg was American Airlines.)"

Pros: "I really like having the ability to upgrade to a more roomy seat the most. I am 6 foot 1in and leg room is so very important to me when i fly, it the difference between a good experience and a great experience. For just a few more dollars i was able to enjoy a great flight."
Cons: "I don't like not having the movies to watch on the back of the seats, although i do understand the cost cutting reasons. It's not a problem, just saying."

Pros: "It was okay"
Cons: "We loaded late and than sat in the plane awhile before we left. No explanation was given. Once we arrived in Charlie we sat on the tarmac for 20 min. No explanation. Than we waited 20 min fir our carry on luggage to arrive. We were told we had to check it. By the time we arrived at our gate they had given outlet seats away. They were not very polity ir helpful."

Cons: "Too cold on the plane"

Pros: "Smooth flight and on time."
Cons: "Small plane. Even small carry-ons had to be gate checked"

Pros: "More options for food like rice chicken or rice beef"
Cons: "Pls have decent meal plans and the seats were very uncomfortable American Airlines need improvement in all areas"

Pros: "the clerk at the boarding desk was kind"
Cons: "delayed"

Cons: "The leg room for seats were horrible especially anyone passed 5 ft 7in."

Pros: "Great service and Manchester is way better than flying to Boston"
Cons: "Your rating app doesn't have a N/A option"

Cons: "The cabin crew were quite unpleasant. Seats are terribly crowded and uncomfortable"

Cons: "Carry on luggage does not fit for the whole plane. We had to check and wait for it to be unloaded in the jetway."

Cons: "I traveled with this carry on for numerous flights and for the last three legs of this trip w/of having to check it. For some reason they made me check it. because I had to spend time at the baggage claim carousels I almost missed the last train of the night back home. Fortunately all is fine, but it caused unnecessary stress."

Cons: "Due to mechanical issues our 8am flight kept getting delayed in 30 minute increments until around 9:45 when the front desk attendants told us the necessary part had to be driven from Seattle and wouldn't be available until noon, and that their was no certainty the part would work, and that we should make other arrangements. So we did, but their earliest we could get us into Chicago was 9:30pm (original arrival was 2pm). We booked the arrangements only to find out that our original flight took off at 10:55 and American didn't even attempt to contact us. The cherry on top was that our flight (which was indirect through SFO) got delayed and we're now going to miss our connection in SFO. So currently looking at 10:30pm arrival in Chicago."

Cons: "The bag hanging down from the bottom of the seat in front of me."

Pros: "Getting the flights was easy, used kayak. Tickets ultimately were purchased through priceline."
Cons: "Flight was a round trip flight and American Airlines (or American Eagle, which is it?) changed my flights and I went from an hour layover and arriving at the time I desired to instead a three and a half hour layover and arriving after midnight."

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."

Cons: "No entertainment"

Cons: "They got us off the plane to get on a another plane there for we were delayed"
