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

I found the seats ergonomically uncomfortable forcing the body to seat slightly hunched. For a short flight I worked on adjustments but for a longer flight, it would be difficult.

I cancelled this flight 2 days before departure but I followed your texts and emails and IF you were correct this flight turned into a nightmare.

Rudest flight attendants ever, waited over 20 for light to be answered and it never was then tried to flag down an attendant who said someone else would come, just needed water to take some medicine Food bad

I was a Wheelchair Assist’ passenger on a London Heathrow to PHL flight yesterday. The process of getting me and my carry-on bag from the ticket counter to the gate was not good at all. It was the worst in my 5 years of experience using this service offered by American. The Philadelphia ‘Wheelchair Assist’ service was, and always has been Excellent! Not so at Heathrow. I was handed off to three different wheelchair drivers; had to sit in a very dingy holding area for 30 minutes while waiting for our gate change announcement; got crammed into a overloaded service vehicle to take me from the holding area to the gate ; was dumped at the end of the line of already-boarding passengers with my heavy carryon and no one helped me up the ramp way at the gate to board the plane. Overall it was a miserable experience!

My flight times changed 4 times since I originally booked the flight. The last time being the day of flight - a 2 hour delay. This meant instead of getting into IAH at 9:30p, I got in at 2:30a. This was very disappointing!!!
