Horrible. Flight was delayed for 4 hours first till 7pm. Then for one more hour. Then again and around 9pm we were finally boarded and waited for catering delivery for another hour. At 10pm we were not interested on food at all. Tired, sleepy we arrived after midnight. Insane.

Horrible. Flight was delayed for 4 hours first till 7pm. Then for one more hour. Then again and around 9pm we were finally boarded and waited for catering delivery for another hour. At 10pm we were not interested on food at all. Tired, sleepy we arrived after midnight. Insane.

I've never seen such poor lack of information at a gate station in 69 years. The flight from COS was to depart at 12:37pm. At boarding time, the gate agent in the microphone mumbled something completely unintelligible. I understood one word. "mechanical". Nothing else. Absolutely nothing else was reported for the next 1-1/2 hours. Past the time for departure, at 12:37pm, the gate agent simply walked away and the station was left unattended, as all of the passengers waited expectantly. The board still said that the flight was ON TIME. That was hard to believe since it was then well past 12:37pm and we all were sitting at the gate and there was absolutely no gate agent anywhere in site. I stopped an employee who was standing somewhere else and said that we can use some information. Much later, the same gate agent said that he will have information for us about 5 minutes but he "doesn't know any more than you do." Of course, five minutes came and went and he did absolutely nothing. One and a half hours after 12:37pm, he opened the door and began boarding. No explanation, no apology. Once we were boarded, the same happened on the plane. We sat. No explanation, no apology, from any flight attendants. Finally, finally, a pilot apologized and explained that there would be a delay. WELL NO KIDDING !

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.

Pilot navigated severe weather/snow storm with skill. Described his intentions clearly

Excellent - explanations were clear staff was nice and flight was comfortable

Most miserable flight ever. We waited almost 2 hours on the runway because the flight was oversold. American offered $1200 credit. Then there was some nonsense about weight distribution. Ridiculous. No food for 8 plus hours on the flight. I will be writing a letter.

Our 9:10 am scheduled flight continued to get delayed all day with no information given from the agents as to why. It wasn’t until I went to the customer service desk and got us switched to another flight at 2:44 pm (that wasn’t nonstop like our booked flight) that the agent finally was able to find out it was due to a fuel leak. I don’t know if our original flight ever took off but I don’t find it acceptable to leave people sitting in an airport all day with no explanation.

This flight was awful all around. Delays on the tarmac at PHL before takeoff and at the tarmac in Chicago caused me to miss my final connection. This was completely avoidable, in my opinion.

Great flight. Quick boarding and departure. No problems. Flight crew were very friendly and professional.

This flight was a horror. Every seat was filled, many of them by passengers coughing and sniffling (including one immediately to my left and another across the aisle to my right). The CO2 level in the cabin peaked at an outrageous 2,847 ppm during boarding and never fell below 1,500 ppm for the entire flight. I wore a mask over another mask and can only hope that that, plus the plane's filtration system, was enough to keep me from getting sick along with every other passenger on that plane. The recording says safety is American's highest priority, but refusing to mandate masks on board when COVID-19 is still a threat shows that the airline's actual attitude toward passenger and crew safety is one of depraved indifference.
