Flight was delayed out of BWI unexpectedly / without a reason given but otherwise ok.

I got a bit sick on the flight, and was so grateful when the male flight attendant explained to me they keep the back row open for cases like mine. He took such great care of me! I was incredibly grateful.

I understand the delays caused by the storm, but that doesn’t mean the systems had to be chaotic. The app showed one thing, the screens showed something else, and the gates kept changing every 10 minutes. It was a nightmare trying to figure out where to go.

Unfortunately, I left my headphone's case in the bag of the front seat. I was seating on 9C. Hopefully the found it and I can get it back. I have not been able to get in contact with Southwest. Other than that, everything went fine.

Flight was constantly delayed with significant changes in time, it was supposed to get to Colorado Springs at 8:30 PM but it got there after midnight.

I don't know why flying out of Sarasota requires two plane changes.

Plane was late. Zero service for 2+ hour flight and it was not that bumpy.

Great flight. Good snacks and drinks. Grateful it was free. The flight from Nashville to louisville, i think her name was Tracy (not sure that's right) super awesome, nice and cheerful. She really enjoyed being at work today! She was the person who scanned the boarding pass on flight wn941. She should be recommended for a raise !

I elected to pay for the upgrades and found very little difference

Flight was hours late, unable to sit next to spouse, I have had so much better experiences. Substantially better, only saving grace was that it was a short flight.

Flight was good- arrived early ! But ticketing with Underpricer and Kayak was poor at best- unnessacarily difficult due to how the ticket were issued

Cabin staff were very disengaged, spoke with no eye contact, dismissive. Disappointing compared to my United experiences.

awful delay, awful communication, zero updates throughout the experience of a giant delay

On Time. AA is late due to maintenance all the time.

Flight attendants were pleasant and helpful. Pilot gave fair warning about turbulence.

Unfortunately the flight was delayed. On a positive note the status updates in the app/text message were good

We waitied for 2 hours for flights to take off. Make us to seat 2 hours in small space is not good.

Wheel Chair Access sucked. I had a guy from Bangaldesh drop me off without taking me to the gate

The amount of gate changes and delays is completely unacceptable. This has happened on 3 of 4 trips between Chicago and Dallas in 2026.

extremely tight seats. seating next to a large person makes the space very uncomfortable. The crew is not very friendly either.
