Flight was delayed. No urgency by American Airlines team to assist those with connecting flights. It was basically you are on your own to run through the terminals to try and make your connection. Thanks, Mary

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

One of our group members was struggling to walk. In Charlotte we asked for a wheelchair and she was accompanied by Desmond. I was impressed by his patience and attention. In Boston she received the same service. I didn’t get the name of the helper but she went above and beyond in assisting us. A great AA service

Better snacks but flight and crew were amazing on this flight

Found that the plane used for this short flight is smaller and therefore the seats are really squeezed tight.

It was the most un-special flight experience in my life.

Plane was super cold. No entertainment unless you were with mileage program Getting off the plane was super slow

Flight was on-time, boarding was flawless and the crew was friendly.

The staff are very, very professional. It's what flying should feel like.

Flight boarded from Gate 159B, the farthest gate in the LAX Bradley Terminal. While the flight operated on time, the first class cabin attendant made no recognition of my being an Advantage Executive Platinum member.
