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.

I was assigned seat 7E, yet my boarding was Group 5, which caused me to have to put my luggage in the back of the plance above `19 or 20 aisle, as passengers who had boarded earlier took the overhead bins in the front. SW needs to monitor bin space and ensure that bin space above the seat are aligned to those sitting near their seats. Also the seating assignments needs to align with group number. Maybe board those last first and so on? Having said the ALL the passengers on the plane were gracious enough to allow me and other passengers in this dilema to retrieve our luggage and helped us along the way. I always love the flight staff, as always their fantastic and I can't rave about them enough!

The flight crew was extremely rude and especially not helpful when our flight was delayed.

Check-in, Boarding and flight were smooth. All the employees and crew was very nice and funny. They gave the kids crayons and workbooks to keep them occupied which was a big win. I’ve flown Southwest many times and that’s the first time I’ve seen that and it is a great addition.

Still a fan of open seating. Flight was on schedule and arrived on time. The 737 MAX is very comfortable.

The flight from American side was good, my main issue this was a part of a partner flight with gol, preventing me to use digital boarding passes and doing checking previous of the arrival to the airport.

The flight was delayed a dozen times and finally took off 3 hours late. American gave us 12 dollar vouchers which barely buys you a water at the airport. Options to rebook were easy to access and complete although I didn't go this route.

I am absolutely furious with American. they shut the door in my face when I was trying to board the flight and kicked me off of it. They made no attempt to call my name or contact me or anything. They just said they gave my seat away. The customer service response has been atrocious. I will never fly this airline again as long as I live.

I spent 12 hrs getting home and had a direct flight that should have taken no more than 3 hrs. The first plane has an issue, was on the plane for over an hour before we had to deplane and move from A19 to A39 to board another plane. Boarded that plane to wait for another 45 minutes for it to also have an issue where we had to deboard. After everyone had went to get something to eat the food vouchers came out and half of us could not use. We then had to wait until 8:00 pm to board and finally got to Columbus Ohio at midnight. We were told that our luggage was on baggage 5. I waited 30 minutes to then realize my luggage was on 4. No notification sent. Horrible communication and I have a priority status.

As with most flights these days it was delayed by about 30 min.

We were stuck with no gate upon landing for 90 minutes. Unacceptable.

The forward head smelled putrid and urine soaked, worse than any head in even transoceanic flights. The wifi stopped working after about an hour of flight.

Every time I fly American they end up delaying the flight significantly and claim it’s due to weather, however, it was a beautiful clear sunny day in Dallas today. Unfortunately, these significant delays occur more often than not which I don’t experience on any other airlines. Yet American Airlines consistently faults the weather and never holds itself accountable for the poor and unorganized service. I will keep my business with Delta, United, and JetBlue going forward. American Airlines should not be part of the “Big 3” considering United and Delta are light years ahead. JetBlue is also much ahead of American. American needs to step up big time

Seems like the ac wasn’t working. It was super hot

American Airlines didn't allow us on the flight as there were delays for a ground stop that couldn't get our flight from Baltimore to the gate. When we needed help rebooking there wasn't a gate agent available to help us either.
