As smooth as you can expect. Some issues with boarding because the previous plane took forever to deplane but overall, a good experience.

As smooth as you can expect. Some issues with boarding because the previous plane took forever to deplane but overall, a good experience.

After a two hour delay, my flight was CANCELLED! No pilot available. Such BS.

I miss the screens they used to have for the long flights. I use a Kendal and it doesn’t work well with there WiFi. I tried my cell and the wifi was not good for it either this is the free wifi.

Update departure times in a more timely manner. We are not boarding on time if the plane isn’t arriving until after our scheduled departure time.

Took off on time and successfully avoided weather that looked to be a problem along the way

Very friendly and efficient and smooth boarding. We were even way early arriving at my destination. Thank you.

The trip was very smooth and they provided great customer service

We kept being told that the flight was full and that all overhead compartments were full and therefore had to check in our hand luggage. We were some of the last people to board and noticed that there was still sufficient space in the overhead compartments. We were obliged to check in hand luggage when there was space and so had to wait at luggage retrieval which took a while to then noticed damage to our luggage - not a great experience!

The flight was quick and to the point. The crew just did their job w/o excessive talking and everything was just perfect.

The seats were crammed and the guy in front of me wouldn't stop reclining. If AA is cramming extra rows in, they need to take away the reclining in coach. My knees were smashed for 4 1/2 hours and I was very close to confronting the passenger in front of me.
