Pros: "All was as expected, lights were out for a late night flight, and attendants were quiet and nice."
Cons: "Our flight was delayed by 2 hours, so that had it's normal difficulties. This was I believe due to the weather, and not a fault of the airlines."
Cons: "Nothing! it was great! I was especially impressed with the crew’s politeness."
Cons: "Nothing"
Pros: "Yes made sure mask was in place"
Cons: "No"
Pros: "I used frequent flyer miles for the tickets."
Cons: "The crew was late getting to the gate. All of them talked to me like I was a child they were disappointed in. No one smiled. I thought all of the crew was mad at us for using their airline."
Pros: "Crew was nice"
Cons: "Lots of empty seats... during covid/social distancing there should only be 2 ppl in a row especially if there is room...it was crowded and not consistent with signs posted saying stay 6 ft apart"
Pros: "Seat was comfortable and the crew was friendly and helpful."
Cons: "They couldn’t have done anything better, I guess their protocol was a bit different because of covid-19 but they did very good and I’m not sick!"
Cons: "Everything was dandy!"
Pros: "Denver airport boarding crew was really Good. Flight attendants not so much. I’m sure they were as tired as the clients after the 4 hour delay"
Cons: "Better communication and resolve Maintenance issues or change the aircraft sooner. Which is what finally happened. Delay started in L.A."
Pros: "Our crew."
Cons: "Flying at supersonic sound."
Pros: "The seats were comfortable"
Cons: "Waiting to board took almost 2 hours ! We were delayed so many times and sat on the plane for an hour after boarding. I was supposed to land at 6:55 and didn’t land til 9:30 and I was late for work due to poor planning. The pilot even admitted in the announcement that there was a crew problem and maintence problem. I was not happy"
Pros: "Nothing."
Cons: "Everything"
Pros: "Nothing extraordinary, just solid positive experience from checking in on my phone thtough disembarking"
Cons: "I like the convenience of the built-in multifunctional screens (like on Alaska flights) that AA are lacking"
Pros: "We didn’t crash and die. That’s the only positive."
Cons: "Before we boarded I listened to a couple described how they always went ahead in line at boarding because no one ever stopped them. They described how they waited until group 3 was called and then went right through. While we were waiting, we watched them do it again. If you need to cram people into tiny spaces to be profitable, then you cannot allow them to make it worse by putting back their seats. I spent 90 minutes with a seat back jammed into my chest. We were ignored when handing out snacks, probably because we were invisible behind the seats pushed in our faces. It was one of the most miserable flights I’ve experienced."
Cons: "It was cramped; it wasn’t overcrowded."
Pros: "Nothing"
Cons: "Had to change our plans, and AA wouldn't give us a refund. We never got on the plane but had to pay for the tickets anyway. I'll never fly AA again."
Cons: "You were out of earphones"
Pros: "We were allowed to board early with my father, who is disabled."
Cons: "Denver airport was a nightmare with my disabled father. We were given a “wheelchair” but no escort through a nightmarish security scene. Airport is terribly designed, lacking clear signage and navigation. TSA was a disaster and no one seemed remotely concerned about my father’s comfort or needs."
Pros: "Captain asked passengers not making close connections to allow passengers with connections to deplane first was very helpful."
Cons: "Flight left late and arrived late making my connection in Philadelphia for a flight to Budapest a very close call."
Pros: "Flight attendants were very good."
Cons: "Pilots need to do a better job of communicating delays. Especially the ones piloting this particular flight."
Cons: "The flight was delayed which caused us to miss our flight in London our family was delayed for 12 hours"
Pros: "Crew on the plant was friendly."
Cons: "I think at least some small food should be offer even tho it wasn’t dinner time."
Pros: "The plane was super comfortable"
Cons: "Long check-in lines in Denver - there were two sky caps outside who had no line which allowed me to reach my gate in time. Otherwise I may have missed my flight"
Cons: "Checked baggage untimely, causing me to miss the train"
Pros: "The flight was on time."
Cons: "The seats are absolutely horrible. I feel crammed like a sardine in the plane. Seriously, can we adjust the seat widths and distance to the seat in front and make them a couple inches bigger?"
Pros: "Great crew! Smooth flight! Landed almost half an hour early!"
Cons: "It was an older plane but it flew fine"
Pros: "There was nothing to like about the way this sudden last minute cancellation was handled."
Cons: "I expected at least an offer of some kind of compensation for the inconvenience. it didn’t and hasn’t happened thus far."
Pros: "Great service, friendly staff. Plenty of in-flight entertainment options"
Cons: "N/A"
Cons: "90 mins late leaving LA caused us to miss connection from Brisbane to Darwin now delayed additional 12 hrs. LA Qantas rep lied and said every 2 hrs there were flights from Brisbane to Darwin and not to worry. Truth is only one per day."
Pros: "Food was good. Staff was polite."
Cons: "Both flights were late leaving. Plus then we waited on board for a long time. Once on board and waiting, no explanation, no updates. No idea what was going on or why. An announcement would have helped a lot. Philky-Prg: Long delays with food , staff was slow on the Philly -Prg flight. Seemed like they didn't want to be there. No info from flight crew. Phily to Prg - Crappy old plane that should not be flying over seas anymore. Applies to both flights unless specified."
Pros: "Good is that they sent you to Finnair to correct AA created break in service...why would they pay for it? AA is just an operator per itinerary! Why would you care if ppl get help with connections!"
Cons: "Checked in online on Finnair and automatically for the second connecting flight...and not the first -AA. So, had to check-in again for the first flight at the terminal. Board passes were printed 2 out of 3 by AA and both had errors - wrong gate for the first flight and no boarding info for the second connecting flight - just blank! AA did not provide connecting info until I found an unoccupied employee at the terminal and customer service lines were about 20 people in 2 locations I went to. The connecting info should be in the itinerary they said at customer service...nope, it was not there either!"
Pros: "seat"
Cons: "Staff seemed exhausted. American has no customer service phone to explain to customers what is going on. Bad experience all together."
Pros: "The crew on both legs were attentive, especially in helping people with connections deplane in Dallas. Boarding was easy. Checking one suitcase for free was good."
Cons: "the first leg of the flight was delayed. The information about when it would leave kept changing at the gate. I would have appreciated some extra food due to the delay... I was unable to get food in Dallas, which my scheduled layover time would have allowed."
Pros: "Good movie selection, there’s new titles available to see and it’s perfect for flight time from Denver to Dallas"
Cons: "We had five pieces of luggage lost during our flight from the U.S. to Spain. When we arrived in Madrid we were told that all five pieces had been located. When we went to pick them up the next day there were only four pieces at the airport. We were told the fifth suitcase would be delivered when it was located. It's ten days later and there's no sign of the luggage. It has taken multiple phone calls to get the information about the luggage correct. They assure me that they have everything correctly documented and then when I call back they haven't changed a thing. It has been a very frustrating process overall."
Pros: "I hope I never fly American again!!! We were supposed to leave at 2.pm, but dud not until 11 pm. The AA customer service staff wanted to charge me $ for my carry on! We missed our connection of course! Had to wait 2 hrs at next airport for a hotel. Did receive food vouchers and luggage was checked in right away (good thing). But overall ridiculous! Missed an entire day due to AA not having another plain? Or not finding another way to put passengers in other flights."
Cons: "Customer treatment and lack of interest on custmer satisfaction. The Denver staff was changed so often they had no clue about customers needs and it was all about making the bucks for the airline."
Cons: "Getting to the airport early and waiting an additional ten minutes on the tarmac."
Pros: "The crew was friendly. Ticket cost was appropriate."
Cons: "Seats were HORRIBLY uncomfortable. I’m slender but tall and in my window seat my head hit the ceiling so I had to either slouch or turn my head to the side for the whole flight. In flight entertainment was awful (some weird sitcom loop) and the WiFi didn’t work with my phone nor laptop. Basically sat uncomfortably sideways with nothing to do for 2 hours. Flight also arrived late, causing transportation issues."
Pros: "Loved entertainment system need bring wireless headset however they will handout some later in flight."
Cons: "Seats were leather didn't let back air out."
Pros: "The America flights were all ON TIME."
Cons: "The seats on this particular flight were not as good for my back and they no longer offer pillows to put behind my back."
Pros: "Ease of boarding"
Cons: "That AA does not follow my preferences. I was assigned a middle seat even though my preference is an aisle seat."
Pros: "I like that American offers free movies thru their app but there was a glitch and I couldn't get it to work!"
Cons: "Couldn't get the entertainment app to work"
Pros: "Great crew with an attention to details!"
Cons: "40 min late and a bumpy ride the whole time but good flight"
Cons: "The flight was delayed 9 hours for mechanical issues and they were not able to do anything. Since booking with Kayak neither Alaska airlines or American Airlines would help in getting us an earlier flight and both airlines said they couldn't help after repeated calls. Won't be booking any American Airlines flights throug Kayak again."
Pros: "The crew was very helpful at each stop even though they weren't responsible for the disasters."
Cons: "Initially we thought we were flying with British Airways. We then had to do some digging to realize it was all out of American Airlines. Then we couldn't get proper boarding passes and luggage tags until one of the crew members spent a significant amount of time untangling each leg of our trip so they were in the proper order. We got delayed by 4 hours in Chicago and missed our connection in Manchester. We had another 5 hour wait there. By the time we got to Dublin, our bags didn't also arrive. After almost 24 hours of travel, we arrived but without all of our stuff."
Pros: "Boarding and baggage."
Cons: "This was a long non-stop flight from Miami to Denver. Over 4 hours. So I took the plunge and bought first class. I always fly first class on any flight over 2 hours. However, I was disappointed. The food was so-so and insufficient. The drinks were also not enough. The video displays were small and poorly located for the movie. The seats seemed uncomfortable. All and all I have come to expect a better experience from American Airlines in First Class. The ticket was expensive."
Pros: "Getting through security was a lot better than I thought. Also, I had plenty of room and the overall ride was smooth."
Cons: "I just wish that there was a little more room and easier ways to earn miles and entry into the lounge."
Cons: "The wifi entertainment stopped working for me half way through the flight"
Pros: "The Denver airport is beautiful"
Cons: "I will never fly AA again - see below"
Pros: "Love the movies!!!"
Cons: "Passengers are allowed to take too much on the plane, which makes boarding & getting off take WAY TO LONG. If American would follow Southwest and allow 1 free bag, this problem would end. E"
