One of the best airlines for fast boarding, on time arrivals, and top notch service!

One of the best airlines for fast boarding, on time arrivals, and top notch service!

The new seat assignment thing is wierd. If you don’t pay for a seat they always assign you a middle seat regardless of how many people are on the flight. Idk… the new company that bought Southwest is trying to make it more profitable, but I’m just not seeing it. The flight attendants aren’t having as much fun anymore. It just feels like the airline is slowly dying. IMO. We shall see if Southwest is the next Toy’s R Us.

Terrible. Even though there’s assigned seating now, they are still the slowest boarding airline of anyone.

The Air hostess were very rude on my flight from Houston to Austin . Their regular communication itself felt a they are shouting at people.

Communication about the delayed flight was poor. We were told to move gates three times but that was bad information. We went from gate 128 to gate 126 and then to gate 123 and back to gate 126. Communication about the delay was bad. Ended up being 1 1/2 hour late getting home.

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

It was good from LAX to Phoenix, But the connection in Phoenix to Tulsa was not that great. The staff on both flights were great. The choice of free entertainment was ok nothing to brag about. The 45 min delay because of some electrical issue wasn't great from Phoenix to Tulsa. We sat there with hardly any air, The seat I had was between windows so the side of the plane pushed in on you. My being a bigger man it then made the seating area uncomfortable. The seats on the plane had no power to connect to recharge your phone or anything. I would recommend that they should look into a slot or clamp to hold your phone to enjoy while watching the entertainment choices hands-free. Also make it possible to raise the inner seat by the window be able to raise the arm rest up to make more room for larger people to set more comfortably. I would also say other then that stop price gouging the airfare or nickel and diming everything. Not fair for people having to fly for emergencies and be paying for higher prices due to the season or holidays. Your making your money either way and the cost of flying is still going to be the same regardless if there's 100 people or 200 people.

Had a great flight. Delayed takeoff, but comfortable. Snacks were good.

Love them will get a Southwest card to track my points and keep flying with them. My family and I were pleased with the services.

I am very please with the service received from Southwest. Although there was a refuel stop in Fl before we got the Baltimore. The service and kindness of the staff was excellent.

The flight was smooth, the crew was great but the plane was quite old

Everything was great until I lost my water bottle and they can’t seem to locate it. I know I left it on the plane though.

WiFi didn’t work most of the time. The usb chargers would work only occasionally for 5 mins and wouldn’t charge after that. Had to keep trying repeatedly at each of the seats in the row.

The crew bent over backwards to thank us for flying and make us comfortable. The food service was quick and efficient. The Captain communicated and said goodbye and thank you as we departed. They really stood out!

Okay considering we had weather delays which the Pilot notified us of immediately!

Generally on time departures and arrivals, clean planes, sky miles membership provides great benefits (complimentary upgrades, etc).

Flight from Fort Wayne to Atlanta was the smallest in terms of cabin space that I've ever seen. A carry on I've used for 20 years BARELY fit in overhead compartment. I'm 5'10" and felt very cramped. Not the best experience.

I am writing to express my dissatisfaction with the poor service and unprofessional staff we encountered when traveling with an infant. Our flight was delayed, and the gate staff failed to manage the boarding process appropriately. Due to incorrect, unavailable, or missing 'pink tag' stroller and car seat check-in procedures at the gate, we were forced to board last. Furthermore, the gate staff was rude and dismissive, causing significant distress to our infant. To make matters worse, one of our checked items—an infant sleeper/lounger—was returned to us broken. Given the unsafe handling of essential equipment and unprofessional treatment, I expect a prompt resolution regarding compensation for the damaged items.

We departed and landed early which was a nice surprise. The boarding process was slow.

N Everything was perfect from boarding to assistance to baggage in Tampa

THe flight was an hour late. You got us on the plan and we sat on the ground for 45 minutes with no information from the pilot whatsoever. Worst flight this year.

Boarding was quick and efficient. We arrived at our destination early.

I'm not sure American is capable of on-time arrivals and departures. When you land at ORD, you almost always get held on the tarmac because your gate is still occupied. I may have missed my connection, but that ended up up being significantly delayed as well. Once again, I finally got home well after midnight.

Same plane as RDU to LGA — internet not working. Pilot issue of some sort at end of prior flight - I was on same plane for my connection. Late/delayed —

Good flight, seated and had a water within 5 minutes. Crew was hospitable.

Didn't make it back on American Airlines due to a maintenance issue. The communication and updates were terrible. I ended up returning on Aero Mexico which had a much nicer aircraft with a large entertainment screen with movies and shows AND they had a nice inflight meal. That was a treat after being delayed 26 hours! I think some additional flight miles, or something should be offered for that long of a delay ---it was not pleasant at all---very physical and emotional experience.

Message about flight cancelation was received late due to being in the air. No explanation, just canceled and booked on morning flight. We had to stay in the airport overnight because there was no transportation offered to get to the hotel that AA had available. Actual inflight was fine.

Buying ticket from kayak instant booking was a huge mistake, never to be repeated again! The Kayak didn’t book the tickets directly, it handed it off to a third party Underpricer, that booked a code shared American Airlines flight operated by Cathay Pacific!! When managing the booking American Airlines would recognize the itinerary but wouldn’t let me do anything stating, the flight is operated by Cathay Pacific so go to their website. Cathay Pacific would recognize the itinerary, neither by reservation ID or ticket number…asking to reach out to the third party Underpricer….calling Underpricer resulted in no help like seat requests, mileage number or upgrade request, 15hr layover accommodation voucher guidance…so net in net avoid booking through three layers of intermediaries

I didn't go from Reno to Phoenix I ended up going from Reno to Dallas to Tucson because my flight rebooked because my Amtrak was late I tried notifying you guys I also don't know what you ask me about my flight because you guys didn't book my flight

A chaotic and uncomfortable experience from start to finish. The boarding process was a disaster; despite group numbers, it was a free-for-all that the staff failed to manage (especially after group 5). Once on board, the "entertainment" was non-existent. There are no seatback screens, and the mobile app selection is incredibly thin. The hardware is severely dated. My seat had zero cushioning left—it felt like sitting on a hard board for the entire flight—and the legroom was cramped. To make matters worse, the bathroom was repulsive, with toilet paper, soiled paper towels and liquid/pee all over the floor. When I did interact with the crew, they provided the absolute bare minimum and made me feel like an inconvenience for asking for anything. Avoid this flight if you can.
