Airline reviews

Worst communication. Delayed boarding for two hours without a single announcement until hour 1 had passed - on time status showing until our flight was supposed to takeoff and the crew had already walked away. No one was boarding. Disgusting part of DFW overcrowded with no AC on a 97 degree day. Then the first app update is that we’d take off in 15 mins… but again no one had boarded a full flight. No announcement in the terminal so everyone is just crowded around a disgusting place with no info for over an hour which turned into two. This was an overfill flight and a disgrace to passenger decency all while likely just trying to fix their own issue of overbooking. The worst airline at the worst airport.

My seat had a worn out cushion, which made it a bit uncomfortable. Other than that, the flight was excellent.

The flight was delayed almost three hours. I understand delays happen from time to time, but this flight was delayed no less than 10 times. I wish the amount of time of the delay was more accurate, versus delaying in 10 or 20 minute increments many, many times.

I thought American Airlines did well considering the adverse weather situation over July 21 and 22. I especially appreciated the consideration given to me when I got stuck in Miami on my way to Boston from Charleston, West Virginia. Thank you for providing a voucher for an overnight stay. Though it was only a few hours of sleep, it was very helpful. I was able to reschedule my medical appointment and got back to the Boston area on the 1st flight out of Miami as a standby passenger. It was very helpful that I was given number one priority on the standby list.

I’ve been on 8 flights with American Airlines in the last 2 months and 4 have been delayed.

The flight was ok, i understand Houston-Dallas is a short distance. The plane is really small: no TV, no snacks, but other than that, all was good. We had a bid delay but luckily it did not affect my connection

I think since I am an AA Advantage member, my checked bags should have been free, but I paid for all 4 of us.

A little late at the start but all worked out well.

The flight from DFW to chs was delayed with multiple gate changes.

A much better flight than our previous. The flight attendant took care of us and regularly checked in to see if we needed anything. Brought us drinks prior to the departure and then a couple more times. Totally makes the difference in how you travel when the crew is checking on their passengers. Great job on this leg of our trip.
