Pros: "Everything was fine. Delta did a great job."

Cons: "Nothing."

Pros: "Service"

Cons: "Snacks if possible"

Cons: "horrible boarding management in SJC."

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"

Pros: "Very informative staff"

Cons: "sat on tarmac for 45 minutes! AFTER landing... unacceptable."

Cons: "Crew"

Pros: "One nickel hostess"
Cons: "PAID FR UPGRADDED SESTS AND THEY WETE GIVEN TO LATE ARRIVALS."

Pros: "Other passengers"
Cons: "It was terribly hot and the attendants didn’t serve us regularly. The skipped us when we wanted cold water:"

Cons: "wish the crews were more pleasant. some were pretty rude to some passengers"

Pros: "The aircratf and on time operation"
Cons: "Gate agents not following AA.com policies to charge extra fees"

Pros: "Was on time."
Cons: "Not eventful."

Cons: "No outlet and waited idle for a long time before getting to get off plane also had to walk my bag back bc there was no overhead storage space in the bins which prevented me from getting off the plane sooner"

Cons: "The bathroom supplies were not replenished. In fact, the facial tissue was empty at beginning of flight. When the toilet paper ran out, I finally informed the attendant and they fixed everything. It seems that checking on that stuff was not part of their routine."

Pros: "Early for arrival!! Love that!"

Cons: "no charging station"

Cons: "We had too little time to switch flights. We were stressed and had to run a lot in order to make it to required connecting flight"

Cons: "It took a while day to get our bags after they decided to put it on the next flight"

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."

Cons: "close it!"

Pros: "Long walk and less than an hour. Very difficult for senior. No assistan e available."
Cons: "The pain from carrying bag between gates"

Pros: "It was effortless... easy boarding and accommodating crew. There was a lot of turbulence so only one beverage service and no food. Would rather be safe than have crew injured."

Cons: "Longer flights should have screens in the headrests"

Cons: "Bad as above"

Cons: "Going through immigration in Dallas is a disaster. The wait is eternal. None-US passengers seemed to get processed faster."

Pros: "I liked nothing."
Cons: "We boarded an hour early. It was at least 80° on the plane, and then everyone got on. The crew was very rude. They ignored everyone in coach."

Pros: "Free beverage"
Cons: "My bag was lost and it still hasn't showed up at the airport. Seems like I would get some kind of credit of some kind for this inconvenience."

Pros: "The pilot was charming, and really hugged Mt. Rainier on the way in - Made for an incredible view in the moonlight!"

Cons: "Delays"

Cons: "They cancelled the flight and put me to fly the next day"

Pros: "Nothing"
Cons: "See above comments"

Cons: "No Free Wi-Fi"

Cons: "The crew was talking very loudly so I couldn't sleep. It's a red eye flight! People are trying to sleep!!"

Cons: "2 different attendants spilled drinks all over me and my carry on"

Cons: "Never made it because first leg was canceled"

Pros: "Flight was canceled due to maintenance problem, American claimed rebooking was someone else's responsibility. I had to talk to 4 people before they rescheduled me for the next day. American's gates/terminals at LAX are also a pain--you never know if your flight will depart from the hinterlands of Tom Bradley terminal, or Terminal 4 or 6, which can mess you up with parking/security screening/scheduling. I will try to avoid flying American in the future. I didn't get any vouchers for the cancellation, either. BD"

Pros: "Great service. Lots of legroom"
Cons: "None"

Pros: "Was called ahead of time to e alerted to flight delay. But I'm still never flying American again due to the rudeness of the crew."
Cons: "We're asked at the gate to measure our luggage. We did, and while it fit, the material of the bag made it look bulky (but upon touch, it was clearly not a full bag). When we said that it fit; the woman literally just scoffed, said "no" rudely, and walked away. We were polite, so why the rudeness?!! Never again AA."

Pros: "Nothing...I had to be rerouted to Chicago to Seattle!"
Cons: "The fact that through no fault of my own, I arrived in Seattle much later than expected and my clients were not particularly happy with the delay."

Pros: "Nothing!!! WORST EXPERIENCE IVE HAD TRAVELING"
Cons: "This was the worst day we have ever had flying. Spent 12 plus hours at the airport! Got on and off planes for 6 hours because of mechanical problems. 7 hours later they canceled the flight due to crew fatigue. The customer service was horrible plane was dirty it was an horrific experience. Alaska booked us with American Airlines. I will never travel American ever again. I'm considering using a different booking site. The experience was the worst I've ever had. Kayak Alaska and American are getting bad marks from me!!!!"
