The guy in front of me was talking constantly, even when the pilot was making announcements. I found this very disrespectful to the pilot and to others.

The guy in front of me was talking constantly, even when the pilot was making announcements. I found this very disrespectful to the pilot and to others.

The TVs on the plane were all broken and inoperable. No snacks or food were served. Plane was very old and uncomfortable.

Takeoff delayed 2 hrs. Boarded on time to find we were missing part of the flight crew. Then informed that they had loaded too much fuel. Spent 1 1/2 hrs sitting there burning off the excess, which included a couple of laps around the runway until we were light enough to fly! Ridiculous!

I especially enjoyed having a lightly packed flight which enabled me and my wife to occupy a three seat area with nobody in the middle seat.

The seats are very small, that is all the staff did a good job.

It was great. The staff is always helpful and polite. The app is great and makes the whole trip and process so easy. They even offer a step to step guide to your correct terminal. And they keep all the information you'll need updated. Anything you can think of! Great experience.

Price was crazy watch it if you Chan he your flight

On time, easy boarding. Anytime you sit in an economy seat, it’s uncomfortable. New plane and the bathrooms were in the galley at the back of the plane which seemed odd.

Terrible service - they don’t want to be there and bad food. Entertainment system in economy from the 2000s

No drink service but there was no N/A as an option to choose. Seats were extremely tight. I am under 5.5 and I bumped my knees have no idea how taller people could manage.

Crew were helpful, pilot kept us informed about turbulence, snack choice was awesome!

It was one of the worst I have ever had. The plane was over booked, and I did not have a seat. When I questioned why because I had booked this weeks in advance. I was brushed off to be advised they are trying to find someone to give up their seat. Only to be advised I would be boarding last. I had priority boarding in group 1-4. When I asked why I had to be last because that is not what I paid for I was advised it doesn't matter you will get a seat. The ticket person was very rude and unprofessional. The gate changed several times and it was going from one area to another area far away from where we were at. I feel like I should have been compensated in some kind of way because of the way I was treated. The ticket agent acted like it was my fault that the plane was over booked. Not one time was I apologized to for this inconvenience.

I have posted the comments in the first flight leg.

First class snacks - stewardess gave out multiples to everyone until there was almost no selection left when she got back to me last in first class cabin. Nothing left that I would eat.

My feedback from the trip to Columbia to Chicago was meant for Chicago to Denver.

The WiFi was out gr entire flight. Had to Diane for almost 1 hour to wait for a gate to open up for plane to dock. Very bad experience.

DELAYED AGAIN and AGAIN and AGAIN - not only that, you delay in 20 minute increments for hours and hours instead of having an accurate delay understanding.

AA was fine....the overall experience was subpar, but not due to the airline due to broader issues

No ground air conditioner for the plane. Very hot and humid prior to take off which was an uncomfortable period of time.

We’ve had a year of delays with American, and this one was another flight to add to that list. It just reduced our vacation by a day! So frustrating. In-flight entertainment (TVs) weren’t working, There was no drinks service due to delivery issues.
