There were five broken seats on the plane. The crew was very rude in telling people they had to get off the plane and get a flight the next day. No call for volunteers, but telling people they had to get off. One woman was flying with her elderly mother and daughter and was told she had to leave or all three had to leave. Fortunately, a volunteer offered to stay. The situation was handled poorly.

There were five broken seats on the plane. The crew was very rude in telling people they had to get off the plane and get a flight the next day. No call for volunteers, but telling people they had to get off. One woman was flying with her elderly mother and daughter and was told she had to leave or all three had to leave. Fortunately, a volunteer offered to stay. The situation was handled poorly.

The flight to Tokyo AA61 took off about two hours late, but then had to turn back. By that time the crew had to be replaced. Then they kept promising to take off in an hour, then in 3, then switch to the next day.

Any sort of gluten free snack option would be nice

They lost my luggage and it didn’t get delivered until the next day.

Would have thought that they would gas up plane before everyone got on board

3 hours late. Not even water offered on a 2.25 hour flight.

I had a carry on and a personal bag. I put my personal item under my seat and on way to the seat I put my bag up. I usually close my eyes and rest as I was on call for last 36 hours. I heard very loud announcements that someone needs to identify their bag. Pretty sure it was not mine until the hostess pointed out my jacket details attached to the bag. I asked why she got my bag out. I got berated and did not want to create a scene. But this person needs to be talked to.

Terrible. The flight was delayed two hours due to weather. Then when we got on the plane, the first pilot ended up timing out and we had to wait for a second pilot. Second pile came on board and we tax it out. Had to return back to the gate because of an unruly passenger. Then the copilot timed out. Had to wait for new copilot. Also had to wait for maintenance to check for fuel. Then found out the second pilot timed out and we had to wait for a third pilot. Was ready to go and then needed maintenance again for another issue. In the end, it was 2 o’clock in the morning when they announced that the flight couldn’t go because the third pilot and the second copilot had timed out.

To start, I’d like to say that every American Airline personnel I interacted with on the ground, especially flight crew, was very friendly and did their best to help me out. Despite this, however, my experience with the airline was an entire mess. The 7:19 PM flight was heavily delayed due to weather, and pushed to 10:30 AM the next morning. Because of this, I had to spend the night inside of the airport. At some point later in the night, I got an email saying that the flight had been canceled. I called the support number, and the representative on the other line told me that the flight was still on and that I didn’t need to rebook. The next morning, no one came to the gate to open the door for the crew until almost 11 AM. By this time the flight crew had been waiting for over an hour, and they had called management to get someone to open the door for them multiple times. Around 11:30, the gate screen had changed to a different flight. I ended up buying a last minute ticket with Southwest airline just to get to Chicago, because the next flight with American wasn’t until 7:19 pm that day. Now, earlier that morning my suitcase had been sent ahead of me to ORD. I went to baggage claim to ask them if I could have my suitcase forwarded to where I was staying. The representative at SDF baggage claim said they could and put the claim in for me. As I was going back through TSA, I got an email that the airline had found my suitcase, but the next step was to send it BACK to SDF. I called the airline support number again, and I made it clear that my suitcase needed to stay in Chicago and to not come back to SDF. The representative told me that they would hold my suitcase at ORD and that it wasn’t going to be forwarded anywhere. Once I got there, I found that they had loaded my suitcase onto a plane to send it back to SDF. Thankfully, I had gotten to the baggage claim counter in time for them to put in a request to bring my suitcase back up. My refund with the airline is processing already, but because of this entire experience and miscommunication at every turn of the way, I will not book with American Airlines in the future.

American Airlines initially postponed the flight. Then they cancelled it an rescheduled us on a flight that would take over 24 hours with multiple stops. They then changed this flight to a reasonable alternative the next day which they later cancelled and replaced with a flight that would take off with an additional 16 hour delay. They blamed weather but I noticed (at 4am) that Delta had direct flights from Charlotte to Detroit. I went on line. Booked it and was in Detroit buy 9am. The interesting thing is they did a similar thing to a family member just 2 days earlier. I don't think I will fly American unless I have to.

Everything was made rather simple, so I appreciate that. All the people I dealt with from entering the airport in Jacksonville to my lonnnnnnng walk to my next gate in Chicago were excellent and very helpful.

Crammed in like cattle waited 30 mins for late connecting flight (flight didn’t wait for me for me when I missed my connection at 2 different airports on outward journey)

Terrible. 3 missed flights and 24 hours delayed with lost bag and promised $100 compensation from United and absolutely nothing from them…

It was a lovely flight. Very attentive crew, comfortable seats, good food and entertainment. Highly recommended. Only difficulty was with their app.

Terrible. Flight was delayed for hours and we ended up arriving at our home at 4am after 20+ hours flying.

Staff was friendly helpful also good timing I rate it a 10 out of 10

Flight was cancelled around 45 -1hr minutes before scheduled take off time due to mechanical issues we hadn’t even boarded yet. Had to reroute to Orlando so someone had to drive 2 1/2 to come and get me… the alternative was go through Toronto and get a later flight which didn’t work for my schedule. The flight attendants barely gave anyone a smile…not the same as flying when a client/passenger was important. Very disappointed. By the way I have never ever made a complaint online about any company with feedback…even when I probably should have. The only good experience was the boarding desk associates who were very professional and got me on another flight with my checked bags…very nice team.

Actually as my experience with air Canada from Canada to Newark it was crazy for me because it was a lot of delays which for me it shouldn’t be like that, but I was able to coup with it so that was my experience I hope next time they will do good on that thanks.

Boarding was challenging as we had to use the stairs from the tarmac. Stairs are okay but a roller bag makes it challenging.

Ensure prepaid food arrangements are appropriately understood by flight crew of who purchased and who did not
