I have executive platinum status with American Airlines. It seems impossible to be upgraded anymore and I’m never offered a cheese plate or thanked for my loyalty.

I have executive platinum status with American Airlines. It seems impossible to be upgraded anymore and I’m never offered a cheese plate or thanked for my loyalty.

In premium economy I was expecting a bit cleaner area. Tables were not very clean. Only one of us received a blanket and pillow. The food was okay. Probably a smidgen better than coach. The crew were very nice but should have done more walk through to at least pick up trash.

We had a 1 hour delay due to mechanical issues, then another hour, then 2, and eventually it was an 8 hour delay. The airport staff was confused about gate changes, as they were not getting good communication. They were trying, but we changed gates 5 times in one hour!

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.

My flights were all delayed , mostly due to technical issues with AA aircrafts. I had to rebook my trip 4 times . I lost my whole day and finally arrived in LAX around midnight. This was a very bad experience with American airlines , I will always try to avoid flying with them

My flight was delayed close to 10 times over the course of the evening. I was originally scheduled to depart at 7:03 PM but did not leave until 12:33 AM, resulting in over 9 hours spent waiting at the airport. The only explanation provided was that the aircraft kept being swapped, with no clear reasoning as to why. Weather conditions at both DCA and Tampa were clear, so that was not a factor. The only accommodation offered was a $12 food voucher, which was entirely insufficient given the length of the delay. Overall, I was completely unsatisfied with this experience. A delay of this magnitude with no meaningful communication or accommodations is unacceptable, and I would have expected much more from American Airlines in terms of customer care.

if it's a mobile only entertainment experience, please provide a place to hold the device in the back of the seat.

Our flight was delayed to Louisville. What made this worse was they did not have another flight attendant to service the flight. This caused an even longer delay. Then when a flight attendant did show up, she chose to "swap" flights with another flight attendant. Therefore, we had to wait longer for the other flight attendant to come to our flight. This is information that the gate attendant should not have shared. Processes and execution at American are broken. Passengers are feeling it. Fixing this starts at the top of the organization.

Both the gate agent and flight crew did a horrible job of expediting the boarding process. It was simply miss managed. The airplane was late to Tampa. Therefore, they should have expedited the de-boarding process and also boarding process. This did not happen and caused me to miss my connection. I ended up with a 7 hour hour layover just to get home. The overall flying experience on American has simply been degraded. On-time performance is a real problem every single week. This has caused me to consider moving my loyalty to an airline that has better performance metrics.

I have never been assaulted they way I was today in Charlotte - shame on American
