Not a bad flight but a long delay boarding and taking off due to the pilot not arriving on time.

I would have preferred a flight voucher and to hop on a different flight. Delayed over 6 hours.

I almost missed my connection in Chicago due to having to wait on a gate to be open I am assuming. Having to run from E terminal to C terminal and I barely made it there before they closed the door. This may not be the actual airline's fault it's crazy how there is so little time between flight especially when they are placed so far apart in the airport.

The Wi-Fi did not work, so you weren't able to watch entertainment on your own device. They did not have wired headphones so you couldn't watch it on the in-seat entertainment screen either. There was plenty of time to do a drink and snag service but the flight attendants chose not to.

Great experience, boarding was fast and efficient, so much so that we arrived to Chicago very early

The flight did not have its customary snacks during the flight. Apparently they were never loaded on the plane.

The seats on this flight weren’t as comfortable as we had expected. Even leaned back these seats left us feeling crappy in our backs. Also we had to use our own tablets for movies, but nothing in the seats in front of us to hold the tablets up.

The male air hostess was rude and didn’t provide good customer service. Didn’t even offer me a drink

This trip was a Christmas gift to our family. We were flying from Lexington to Palm Springs. When we were checking in the ticket agent said one bags was over weight by 4 LBS. We were flying first class which has baggage weight of 70 LBS per bag, one bag was 54LBS. We then had to take items from one bag to another. The agent also saw we had a dog with us. Once on the plane we were seated with the dog in the carrier. The United ticket agent came in the plane with two other people, I believe one was TSA and the other some security officer. The United agent said we had not paid for the dog ticket. We had paid for the ticket when we purchased our tickets. She did not give me time to find the email receipt. She then threatened all three of us with either I come with her or she would have all three of physically removed from the plane. I left the plane to pay for another ticket. She had to take my credit back to where we checked in. She acted as if it needed to be done immediately. She said we had 3 minutes. We then sat at the gate for approximately another 45 minutes. This was so embarrassing…to be threatened to be removed from a plane that we paid for all tickets including the dog. The flight attendance on the next leg of our trip were not very attentive to the passengers. On the plus side all the flights were on time. All in all, this was a miserable way to start a holiday vacation. United Airlines showed no compassion towards the whole incident. I feel we were purposely neglected.

My seat had a worn out cushion, which made it a bit uncomfortable. Other than that, the flight was excellent.

Take this flight regularly. Every single week same thing. Departure delayed. Make up some time in the air. Land at ORD and then wait for gate in "L" concourse Terminal 3 for 30-40 min-which yields a very delayed final arrival. Plus I get to taxi around and see every runway and drive over the bridge (IFKYK) over the expressway 2-4 times in most cases. Change the sched of incoming plane/work with FAA to improve traffic flow at ORD/change the timing of these flights. Whatever it takes. But do better.

- flight was delayed several hours due to weather (understandable) - flight delayed further and we were told by attendants "we are not sure where the pilots are but they are on their way" as we have to find different pilots for the flight - announcements over the PA were somewhat unprofessional by the attendants, seems they need more training and were not reading off the script. They showed their young age and immaturity in their communications with the passengers. They were not clear and lacked professional communication language. - going from a hub to hub we were also parked at the tarmac at ohare for an additional hour and kept being told "few more minutes". Please just let the passengers know the real wait time instead of hiding the truth. We understand there is traffic and weather delays, but we just want transparency. There are several logistics of our lives that revolve around what the attendants and pilots are sharing with us but they are not being transparant.

Boarding and Delays The boarding process for my American Airlines flight from Copenhagen to Philadelphia was a bit tricky. We experienced a gate change that required a long walk to a new area of the airport. Additionally, boarding was not via a jet bridge; we had to take a shuttle bus to the plane and then carry our luggage up the stairs ourselves. Furthermore, the bag drop didn't open until about 12:20 PM, which was only three hours before our scheduled departure. This meant I couldn't drop my bag off early and had to wait outside of security in order to drop off my bag and use the kiosk. The bag drop self-service kiosks also didn't open until about 12:00 PM when an American Airlines employee unlocked them so that we could print out our boarding passes and bag tags, which further created a backlog. The flight was delayed by over an hour because we had to wait for one of the tires on the plane to be changed. Flight Attendant Professionalism On a positive note, the flight attendant was very professional when handling a passenger who was sitting in the wrong seat. Even though the passenger was persistent and reluctant to move, the flight attendant calmly ensured the assigned passenger could take their seat. Kudos to the flight attendant for keeping his calm and composure, not allowing the issue to escalate, and handling it well under pressure while a line of passengers waited in the aisle to board. In-Flight Service The in-flight service was also fast, prompt, and efficient, although service had to be suspended for the last two hours of the flight due to weather and turbulence, which was outside of the crew's control. Limited Flight Options Please note that American Airlines only operates one flight per day in and out of Copenhagen. This means there are limited options available if your flight is delayed or canceled, which is something to take into consideration when booking.

Better perks for corporate employees whom travel often and spend a lot of money with the airlines. Snacks were terrible chips crackers are ideas. Flight and crew were great comfort was fine entertainment not so great so so called status members means nothing

Delayed flight. Missed connection, AA put us on a later connecting flight. The connection flight was delayed 4 times and we had to deplane. Didnt get home until 3am, when I was supposed to be home at 8:30p. Zero compensation offered from American. I would not fly them again.

Better snacks but flight and crew were amazing on this flight

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.

They needed to de-ice the plane. Apparently airlines have a problem keeping their de-icing vehicles in good repair. After we backed away from the gate we sat and didn't move for nearly an hour. Nearly an HOUR with minimal communication from the flight crew. Eventually the sun took care of what American Airlines could not and melted the minimal ice. We finally took of a hour late which, in turn, jacked up our connection in Chicago.

We were delayed in Charlotte for almost 2 hours because American Airlines didn't have flight attendants for our flight.
