Very pleasant, on time and I would like to particularly express my gratitude to Michelle, the flight attendant who was not only very kind and friendly but also went out of her way to help me find and retrieve the airpods I had lost while asleep.

Very pleasant, on time and I would like to particularly express my gratitude to Michelle, the flight attendant who was not only very kind and friendly but also went out of her way to help me find and retrieve the airpods I had lost while asleep.

Cons: "My charger port wasn't working for my phone, and the movie in wanted to watch wasn't working either."

Pros: "Entretaiment"
Cons: "Seats (too small and little distance between them) Food (although this time the breakfast was better, AA has the worst food selection compared to other airlines. I just have to get dinner at the airport or eat at the lounge before bording) service is also mediocre, flight attendants are lazy"
Pros: "Shory"
Pros: "miserable. Flight."
Pros: "Short flight."
Pros: "great trip and crew"
Pros: "great trip and crew"
Pros: "The crew"
Cons: "The food"
Pros: "Nothing"
Cons: "spending $600 on a one way flight with you today has been the worst experience and rip off ever! Delayed in Hartford 6 hours. Changed my layover flight in Dallas. Now Dallas delayed 1 hour."
Cons: "Flight was delayed"
Pros: "The dinner was good"
Cons: "All the flight attendants were hanging out in the back. Socializing like we were invisible. They seemed to prioritize one another over the passengers. It felt a little odd."
Cons: "Gate agent told me it wasn't his job to quickly verify if my luggage had made it on the plane after my 10 minute sprint in PHX. I know at my job, I don't get the luxury of telling customers "it's not my job", especially when the customer has had a bad experience with us."
Pros: "Enough leg room. Free movies"
Cons: "Nothing really"
Pros: "The staff was very helpful"
Cons: "I did not like the fact that, I was ask to help a non English person, whom spoke French find their way to the departure area from check in. I could not understand their broken English. That I feel is the job of the person or staff trying to check them in."
Pros: "Excellent. on Time. Friendly crew"
Pros: "Planes were punctual and smooth flight"
Cons: "don’t know! didn’t get to phoenix because of plane issues"
Cons: "The flight was a bit delayed and was not cleaned at all, may be because of short of time, but minimized the further delay, so acceptable."
Pros: "The food was fabulous!"
Pros: "Food was really good, crew members fantastic. Boarding was a little messy, a mix between anxious passengers and weak organization."
Cons: "The entertainment system didn't work and there was no way to solve it. It should've been checked before. It was a 9-hours flight with almost nothing to do."
Pros: "one more bag"
Pros: "Entertainment service and film variety was good"
Cons: "Seats are too small, no place for my legs"
Cons: "New plane and excellent service. The flight was on time and the crew was very servicial."
Pros: "Good food"
Cons: "Online check in for one of our two passengers was impossible. Simply never worked. At airport check in desk, manual data entry errors during airport check in caused issues during customs at the end of the flight. Also we were not seated together initially even tho reservations were made months in advance. Airline online check in was pushing us to pay extra for seats together."
Cons: "Free seats in economy class are way too squeezed for a 10 hours flight."
Cons: "Essentially a bus ride with the comfort of a wooden bench."
Pros: "Prompt boarding"
Cons: "I could never sync in the entertainment app and wifi"
Pros: "Seat was comfortable"
Cons: "Gate agent told me my bag would fit under seat but when I got on board found it would not and had to do gate check."
Pros: "Entertainment package at your seat was easy to use and had a wide variety of movies, music, etc. to please anyone. Plane was new and everything worked. Arrived early!!! Captain was best attribute of the crew."
Cons: "Crew seemed to be robotic, no personality, just doing a job. Food was just OK, nothing special, but at least it was somewhat tasty."
Pros: "Very nice gate crew, efficient boarding, quick and efficient takeoff"
Cons: "Found out that a lot of Argentinians do not obey the crew rules. Before the seatbelt sign turns off they already start moving to the front of the plane. But off course is not the airline duty to teach manners."
Cons: "American Airlines delayed my flight over 16 hours. Very unhappy."
Pros: "Nothing special. Horrible food (the worst in years). Cabin crew try to manage but a refurbished plane doesn't justify more than double for a substandard bussines class."
Pros: "The flight attendant lady from 1st class/Business held my suit jacket for me to grab on the way out. Simple thing, but very thoughtful and kind. Love it."
Cons: "The negatives are puny compared to what made me happy in this trip. Thanks AA! Please thank that nice lady for me!"
Cons: "Flight was delayed 4 hours so we missed our connection. The entertainment system was down during the flight and all they did was apologized over the speaker. There was no rep waiting to help upset customers so we had to wait TWO hours in line as there were only 2 girls at the counter when there are 6 counters. They were completely unapologetic and although they set us up on another airline to fly back, the whole experience was completely unsettling. AVIANCA NEVER AGAIN!!!!!!!!!!"
Pros: "The crew really good"
Cons: "People at the bs as airport didn't organize everything. Lines all over the place and two flights cancelled to the same destination in less than 24 hours! Got lucky that they didn't move us onto a next flight because there was a domino effect on the flight. I stead of solving a problem for 200, they began to make problems for 600."
Pros: "On time, very friendly and accommodating crew!"
Cons: "My screen didn't work BA to Dallas but I didn't ask for help either!"
Pros: "Movies. Upgraded to more spacious seat."
Cons: "Dry dry dry. Hard to sleep."

Pros: "Right in time and crew very responsable."
Cons: "The audio for film's didn't function in many places of the plain."
Pros: "It was a short flight to begin with but due to winds it was delayed."
Cons: "Due to bumpy air nothing but water was handed out to cabin passengers. 1st class managed tho. We were asked to stay seated almost the entire flight, although people still went to restroom as needed. After a late night it would have been nice for a little bite to eat. But apparently mother nature thought otherwise."

Cons: "Not social distanced full flight"
Pros: "New plane"
Pros: "Flight attendant was good"
Cons: "Everything else needed improvement"

Cons: "I've never had a problem bringing two backpacks on a plane but United makes sure they charge you for that second bag even though there was plenty of overhead space. I also went to the kiosk and it printed my bag check receipt but not my boarding pass and I had to run back from security to get it when I realized. Crew was nice and flight was smooth but everything before that point I could have lived without."

Pros: "Food was just ok. Fly twice with delta international and was spoiled,"
Cons: "Crew no customer service, the boarding lines international & domestic were a jungle. Even boarding pass line to check in lugguage had 200 people in it and only one flight out. No fast Kioskos and many people standing around 6 to be exact not helping and just standing so people don't go into another airlines lines. Useless"

Pros: "Staff seemed lively and created good atmosphere; thank you."
Pros: "The crew was very pleasant and professional in spit of all the grumbly passengers."
