Long story short, it was one of the better flight experiences I've had in some time when compared with other airlines.

Long story short, it was one of the better flight experiences I've had in some time when compared with other airlines.

Flight was great! This flight from Atlanta was even better than when I paid for Comfort from SNA to Atlanta.

Connection flights should be spaced out farther because too close I missed my connection.

Definitely a southern flavor. Cordiality was evident even though no drinks or snacks were served.

On time! There were plenty of airport employees who were able to keep us moving in the right direction. The crew on the plane were professional.

Left /arrived on time. Decent seat space. Like the wifi/plugs and entertainment. Windows and tray table were kinda gross. Attendants didn't start snack service til 40mins before landing. Two rows before us, captain came on to say there's turbulence and recalled staff to seats. So, no drink/snack. Later, attendants didn't stop to see if we had trash nor even look our way. Felt invisible! Almost all pilot announcements were not only unintelligible, but so quiet. We had no idea what she said.

Average seat comfort, a drink and chips were provided, early boarding because we checked a carryon at the gate was nice. Ticket pricing shenanigans, including fees to pick a seat, check a bag, and get food onboard - evidence the industry is reinvigorating last century’s strategies- destroys the experience before one ever arrives at the airport. It’s difficult to recognize any value or sustain loyalty in the end-to-end process making air travel more drudgery than pleasure.

Gate agent was unhelpful for handicapped boarding. Flight attendant seemed untrained.

No service flight that took 5 hrs and a stop at an unscheduled airport. Crew and pilots did their jobs

Clean planes and not take my comfort class seat away.

Our flight from JFK to Madrid was delayed. We had to go from one side of the Madrid airport (Terminal 4s to the far end of terminal 4 - Gate K98) to our gate in less than 30 minutes. Put passport control and security/baggage check and that’s very hard unless you’re Usain Bolt. I called Iberia Airlines and the telephone customer service told me that I was going to have to pay to re-book. Luckily the help desk in the airport (who was dealing with dozens of people from the same JFK-Madrid flight) did not charge us extra to reschedule to a flight 8 hours later. They also gave us a voucher for breakfast and lunch. Glad the actual person at the airport had some actual sense.

As always, most AA flights that we fly are almost ALWAYS delayed and that too multiple times. Very frustrating

Boarding was smooth and seamless and the flight was without incident.

For an long range economy flight I feel more space and more meal options need to be offered for flights over 5 hours

Our flight was repeatedly delayed for maintenance problems: scheduled for 9.30am, eventually delayed to 7pm! Very very inconvenient! AA should have provided a substitute plane much earlier.. On the other hand, Customer Service crew in Charlotte helped us to reach NY (LGA) by late afternoon. Thank you Patricia!! The actual flight was quick and very comfortable. As always a. excellent, professional crew. [no food on a a short hop).

Take-off delayed an hour because of a missing flight officer, so,arrived in Charlotte lates causing many passengers to miss connections. Otherwise a very good flight, safe and comfortable, with an excellent professional crew.

Little time between flight from Dallas to flight to Gainesville. We chose this one, 43 minutes between, because the price for a connection with at least an hour between, was so much higher. Had to ask passengers on the Dallas flight to please allow us to deplane ahead of them. The economy passengers allowed this. We had to walk very fast to the next gate, 35 gates away. Thankfully all in the same terminal. Getting to the small Gainesville plane was a little confusing as you enter an area that is boarding many small planes at the same time. We stood in the wrong line for about 15 seconds before realizing it was not our Gainesville flight. Since I had boarded at this gate in the past, I knew to check the signs carefully so we weren’t lost. The first class seat experience was wonderful. I really enjoyed the upgrade. We were offered an alcohol drink as soon as we sat down. I got something different but it was a great gesture especially since we really had to hurry to make the flight. We had packed expecting we might miss this connection, but made it. Our luggage didn’t miss the flight. American Airlines delivered our bags to our home the next day. That was very convenient!

The plane was large, not full, but one with 3 seats near each window and 4 in a row in the middle of the plane. There were screens on the backs of the seats for entertainment and information. To use the entertainment one needs ear plugs that physically plug into the screen. My husband had some he let me use as I only had blue tooth type. The stewards gave out some headphones to some, but when my neighbor asked for some, the steward said no. So maybe they ran out? Idk. Bring the old kind of headphones or earbuds if you want entertainment in case this is the type of entertainment offered. We had a very tight connection in Miami. 43 minutes. The other economy passengers allowed us to get ahead of them because I asked if we could since we were near boarding time for our next flight and 35 gates away. They were extremely kind. First class wasn’t going to allow us to pass through. We did make the next flight. Our baggage didn’t, but they were delivered to us the next day and we were prepared with essentials in our carry on packs.

Food is what you expect on a plane. Nothing gluten free. But that is expected. Drinks, apple juice, was fine. Seat, what I expected. Fine.

The check in agents in PHL and gate agents had to have been the rudest women that I have ever encountered; the agent weighing the bags at check in screamed continuously at all of the guests as did the woman at the gate.I have Executive Platinum status with AA and fly a lot with AA but these ladies were the absolute worst I had the displeasure to encounter!
