Plane was delayed for 3 hours, due to situation within aa control. Information was shared poorly. We sat on tarmac for over 40 minutes after the 3 hour delay.

American notified via app that the flight was delayed. However, when I went to the gate, they were already boarding and had not updated communications that they had pulled the flight time back. They made the entire flight re-check in which by this time I had lost my exit row seat and ended up in a middle seat. As a 4 decade flyer of American and Exec Plat, my expectations for the company are that the customer service would be better. This unfortunately is no longer a strong point for any of the major airlines including American. They are basically city buses flying at 30 thousand feet.

Very good, boarded and took off on time and landed early

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.

Not much space for someone 6 feet high in normal economy seat. My knee hurt

Getting to Scotland with no luggage (no medicine, no clothes and no club) on golf trip very disappointed

Quick flight again no one illness why there were multiple delays and changing of the gate number.

The check in agents in PHL and gate agents had to have been the rudest women that I have ever encountered; the agent weighing the bags at check in screamed continuously at all of the guests as did the woman at the gate.I have Executive Platinum status with AA and fly a lot with AA but these ladies were the absolute worst I had the displeasure to encounter!

Delayed delayed. Poor professionalism. Our seats changed and we pay for them

Fine. Nothing to write home about. The plane left on time, and arrived on time.
