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. 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. 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. However, the in-flight entertainment screens and the overall interior of the plane were somewhat older. The system did not offer streaming to personal mobile devices, so we had to watch movies on the seatback screens.

the first flight smelled like urine Ac didn’t work pathetic experience

We were delayed due to a mechanical issue, but the gate staff and then later captain were giving thorough and frequent updates. Ended up being delayed about an hour, but we did get out, so it was overall a good flight!

My luggage never made it, I booked business class only to find out I’m sitting in the back. Very disappointed with the reservation

We were treated politely and the crew was nice. Again no one knew why there was a delay. Food was hot and a lot was offered but bad in taste. Seats weren’t the worst but for a long flight your legs ache from it. Entertainment was old not very interactive

The Phildalphia to Allentown portion was a BUS, not a plane. All was as expected.

Terrible. I did not like the delay without recourses to help passengers to get to their destinations. AA used to offer coupons for food and overnight accommodation, but not this time. The flight planning was terrible despite of all the current technology available; AA could have informed passengers better that the replacement flight is impossible today, instead of stringing passengers along for 6 hours before cancellation, so that passengers can make earlier alternative arrangements to get home.

It was a bus not a flight. Okay bus ride.

My trip was delayed for more than 3 hours without any explanation. Also I have a business meeting that I lost.

If we travel with carry on expected to being able to carry the luggage. Could be good if take in consideration the date of reservation to do that
