Cons: "Lack of legroom in economy"
Cons: "Food was bad."
Cons: "Poor WiFi. Paid extra to get it, but didnt sporadic at best."

Pros: "Bags arrived on the belt quickly"
Cons: "Why is there not saying precheck to use after you've been funneled through customs? ATL is advanced enough to have kiosk for arrival, even for those confused and not with global entry, but then forces you to wait in security line instead of the typically faster tea precheck line. Every minute I'm in line, I'm not spending money"
Cons: "Enforce your baggage size and number limits. A significant number of passengers take bags onboard that are oversized."
Pros: "The landing experience."
Cons: "The organization of serving meals."
Pros: "Small plane. Very good service. Did not suffer through the crazy multi level boarding calls that some airlines have. No super secret airline clubs that board first. Flying into the Marine terminal is the best part of the trip."
Cons: "The wifi didn't seem to work at all on the plane."
Pros: "I enjoyed not having a layover."
Cons: "I do not like being charged to bring a bag. I feel like a 560 fee should include a bag."
Cons: "We finally got toward the runway then had to sit there for about 25 minutes because there was a technical error."
Pros: "Nicole and I really like the Economy Plus seating with the extra legroom. It is a good compromise between sitting in cramped Economy seating and spending way too much money in Business Class."
Cons: "I wish that the Seattle Tacoma Airport has an Admiral's Club Lounge. Actually, I might as well fess up... I wish that EVERY airport had an Admiral's Club Lounge. I also wish it would be possible to "gift" miles to family members. I would love to have my son and daughter-in-law take advantage of my miles to go on a honeymoon."
Pros: "I was moved up to seat 9E from 16E move leg room makes a difference"
Cons: "I had started a movie on the earlier flight but I could not finish it because it was not offered on this flight"
Cons: "Better snacks."
Cons: "Weather related, mostly, so not AA’s fault"
Pros: "Boarding process was really unsmooth here as well. Little delayed. Thankfully this crew was really polite. And not screaming at people this one flight."
Cons: "Ether bursting process."
Pros: "Was on time."
Cons: "Not eventful."
Pros: "Excellent flight crew, attentive and polite."
Cons: "Fellow passengers didn’t feel there was adequate space, causing issues with armrests."
Pros: "Left on time, relatively comfortable considering I had already spent almost 9 hours on a previous flight, landed 30 minutes early"
Cons: "Mixed feelings about the entertainment app, I was pleased that something was available at all, however had the person sitting next to me not mentioned I needed an app to watch the in flight entertainment moments before it would have been too late to use the internet to download it, I would not have been able to use it, unless paying for a limited time package from AA to use the internet to download the app. A better job of advertising of the gogo app is needed more than the booklet in the seat pocket. Also I was only able to watch one movie, after that the system kicked me out saying high usage was making it not work for me. The gate changed a couple of times which had me trawling up and down the H and K concourses, could have done without that after the 9 hour journey I had already taken."
Pros: "The crew was very friendly with our girls and accommodating with switching around our seats so we could sit together."
Cons: "There weren't any screens, which surprised me since our 3 other flights had them, and we unfortunately didn't have a backup plan. Our kids were disappointed. Also in order to sit with our young children we were only given the option to sit in the very last row that doesn't recline which was difficult seeing as the flight took place in the middle of the night according to our bodies. No actual food was provided despite it being a 6 hour dinner time flight."
Pros: "Lovely service, but less comfortable plane... nothing terrible though"
Cons: "This agent spent 30+ min to check us in through a connection flight to Seattle. He couldn't find my wife's reservation, when it should be in the same reservation as me. He tried 5 times, and still failed. Later we found out at the gate that he was using the wrong name (same last name, different first name). Luckily the American Airline agent at the gate was more than competent and efficient to correct the issue in 5 min."
Cons: "Dry / borderline rude staff and hostess. Dated plane. Tiny seats. But that is pretty much the baseline of airlines in the US. When will carriers start to take note from International carriers..leaps and bounds ahead."
Pros: "Boarding and service was nice"
Cons: "We were delayed an hour because the plan was in the hanger! Why? We were all there, didn't American know the plane should be at he gate! No escplanation as to why the plane was not there other than it was in the hanger! Airlines need to let the customers be flexible especially when are!"
Pros: "Clean environment of the terminals and the speed of the shuttle."
Cons: "no comment."
Pros: "It took off on time and life was good."
Pros: "Great service!"
Cons: "Same as previous response."
Pros: "Had good bathroom access and place to stand in the back galley so you could exercise and stretch as this was a connecting flight and I had been in the air a long time."
Cons: "The older woman stewardess was rude. I tried to give her my papers and she ignored me. So I put them in the pocket and the man next to me saw what happened and she responded to him. Curt. The plane is old and no individual TV. The food choices were very limited. I felt like cattle rather than a relaxing flight. Flying use to be fun and exciting and part of a great trip. Now it is endured to get on a trip."
Pros: "I loved how sweet the crew was. I loved the movie selection."
Cons: "The seat was completely uncomfortable. My feet are swollen and my back hurts still."

Cons: "Wasn't enough room.. kind of tight.. Couple more inches all around would have been perfect though"
Pros: "Ease of travel"
Cons: "They cancelled the flight and put me to fly the next day"
Pros: "I had my first experience in the Admiral's Lounge at O'Hare and enjoyed it very much."
Cons: "My traveling companion's tray table was disgusting when she folded it down for beverage service. She asked for a wet towel and the flight attendant was snarky but went to get one without even looking or asking to see what the problem was. Her entertainment console wasn't working so they reset it but instead it reset mine (two seats over) they did this again and I let them know it was resetting mine. I was told that I was not in the seat they were resetting for ...I inquired if perhaps they should try to reset mine and see if it would, in fact, fix hers..it did. When she slipped off her shoes the carpet was soaking wet. This was a really crummy, crummy flight."

I begged not to have to check because I was flying to Nicaragua and was worried my only bag would get lost. I was right -- it did not arrive in Nicaragua until the next day. We sat on runway for 45 minutes before departure so United could fix BOTH sets of the plane's wings lights. Why did they not discover that at any time BEFORE we all boarded or while we were boarding -- NOT first when deciding to pull away from gate. Delay caused many to miss connections."
Cons: "Short-staffed, so short tempered workers.kiosks did not work. Nickled and dimed on everything. Like flying in prison. No light and a cold hard bench seat. Awful."
