Boarding process, crew were good. But the seats were so uncomfortable that was all I could focus on. I literally had to sit forward so that all 3 of us could fit in row. I will try to avoid Southwest in the future for any flights over 60 minutes.

Boarding process, crew were good. But the seats were so uncomfortable that was all I could focus on. I literally had to sit forward so that all 3 of us could fit in row. I will try to avoid Southwest in the future for any flights over 60 minutes.

1.5 hour delay, poor service, no compassion from the crew. Terrible experience

Great flight, 47 passengers on a 180 seat plane. Stewardess was pleasant and cheerful.

Short flight with plenty of open seats. Drinks and snacks were still provided even on such a short flight. <1 hr

I liked the crew member who gave flight instructions on "in case of a problem:. The seats are so small that only a young teenager could sit in middle seat.

Great experience flying Southwest. The crew was really kind and helpful, and very friendly with our toddler.

Very good. Sad to learn Southwest is going start to charge for bags

Our flight was diverted from being a non-stop to getting within 150 miles and requiring another plane. We heard 4 or 5 different versions from SW as to why we had to stop, then wait for a replacement plane. Five hour delay, weather did not come up as a single excuse.... communication was not clear and well explained. No one really took charge!

My flight to Chicago left and landed early. My return flight left two minutes late and arrived 2 minutes late. My seat selections were ideal! There were no snacks going to Chicago and no snacks on the return trip. There are no charging outlets on board.

WiFi on the flight was not working. Thus, entertainment options were limited.

Delays on all NY flights. There was no communication on why but they didn’t say it was weather. Other carriers were not delayed.

Extraordinary service in business class, and very good breakfast and snacks. A really lovely flight.

They cancelled our flight without warning OR a refund. Never doing business with American Airlines again! This is the second AA booked trip in a row that we've had challenges with.

I got bumped due to weight restrictions even tho there were empty seats on my flight. I got put on an other flight with a stopover. My flight that originally was going to take 5-6 hours ever up being 14+ hours and my luggage arrived to my destination without me because I was made to check in my luggage on my original flight when I was deemed ok to board only to be asked to deplane. Worst flight experience.

Flight cancelled. Added a day and a half to my travel. American Airlines DID put me in a hotel for two nights, but have not given any money back for any of this! I spent money on an apartment at my destination that I basically wasted because I could not arrive.

I was pleasantly surprised with an upgrade at boarding. I finally had a mostly gluten free food options and a very attentive attendant.

It was good. It’s been a long time since my wife and I fly any where and things have changed. Our trip was to see our new grandson. We fly economy and that was not good for my bad back. It was a quick flight but uncomfortable.

Staff at the gate were incredibly rude, hostile and threatening. Never fly American Airlines.

AA had a nationwide tech glitch today and after two connections snd hours of delay, I arrived 7 hours late to my destination

The plane was very warm and the crew turned on the lights for the entire snack service.
