Flight was delayed over 3 hours. Planes were dirty. Staff indifferent. And they serve vegan pretzels as snacks.

Flight was delayed over 3 hours. Planes were dirty. Staff indifferent. And they serve vegan pretzels as snacks.

The flight was smooth. The Southwest experience has degraded overall, but this one was okay.

The checking experience in Orlando was terrible, almost missed the flight. Too many travelers and Southwest completely understaffed.

no service at all due to turbulence. they should've at least given us snacks, there were only 10 people on the entire flight.

For the first time in a long time, the Wi-Fi actually worked the entire flight! The flight crew was amazing as usual.

Great flight. I didn't get a drink because I was asleep whole on the flight.

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.

WiFi was not working and didn’t have a beverage service

Only one drink pass through the cabin for a 4 hour flight. Quite rough and bumpy landing.

Excellent! Only question is how we check in at exactly 24 hours in advance and end up at the end of the B boarding group

Crew was great. Seats are cramped and uncomfortable and I’m a small person.

Awful. Delay after delay. And then again on the tarmac.

Kept changing the takeoff time and the moved it up so arrived when boarding had already started. Then sat waiting to taxi in for a long time

Food was not Good Nuts came very wet & not tasting Good Main course I asked for Steak they got me Chicken because they don’t have more !!!!

It cancelled and we were unable to catch our connecting international flights.

Leaving at 7 when scheduled to leave at 4:20 - you tell me. Understood there was a ground stop. Then having to "reboot" the plane because of a lighting strike, also understood. But basically the flight was a "clusterf#$%".

On boarding crew at the airport called in the boarding numbers too early meaning before the previous line was completed resulting in later numbers getting to board ahead. Also she asked those who boarded from number 3 to have the tags in their carry-on bags and leave it in the jet bridge. Most of the overhead bins were empty though. This is more work for the ground staff in addition to more inconvenience for passengers waiting to get their carry-ons from the jet bridge.

Like the fact that the boarding was expedited. But the delay and chaos around the onboarding was not appreciated.

Not a bad flight but a long delay boarding and taking off due to the pilot not arriving on time.

Flight was great. On time. Pleasant crew and responsible passengers. My only disappointment was that there was no coffee or tea offered. It was a short flight but a coffee would have been appreciated for what the price of tickets are now.

Flying on this airline is nothing short of a full blown circus clown show. On a recent return from my mother’s funeral, my only available choice from IND to PWM was American, which I hesitantly booked as I rarely fly them for many of the following reasons and never will again. I was booked IND-PHL-PWM totaling about six hours. The flight was cancelled due to NE weather. They rebooked me on a two stop flight IND-DFW (Yes DALLAS)-PHL-PWM, still all on the same day. After arriving in DFW, they continually delayed the DFW-PHL flight due to maintenance issues on the arriving flight. Finally it was delayed to the point that my PHL-PWM connection was no longer possible. They then rebooked me thru LGA with the short flight the NEXT DAY to PWM and offered to put me up for the night in NYC (or so I assumed). The flight DFW-LGA was then delayed so much that I asked to be put in an earlier flight with a lessor delay. Throughout this day chats with their AI assistant were useless as were subsequent chats supposedly with a real person(?). Only one customer service agent in DFW was actually helpful and appeared to care. Upon arrival at LGA post midnight, they issued me car and hotel vouchers in Trenton NEW JERSEY at a very old Howard Johnsons ONE HALF HOUR from LGA. The hotel was an $85, 1.5 rated hotel in a very sketchy area of NJ that I would have never voluntarily booked. As I prepared to catch the car back to LGA the next morning I received a text that my flight was cancelled. TWICE IN TWO DAYS. I went to LGA hoping to have AA book me on an earlier Delta flight. The full service line was at least 200 people deep, so I tried to reach a real person agent by phone. After 1/2 hours on hold I gave up and waited for my later LGA-PWM flight. It actually started boarding on-time, but only shortly after announced a maintenance hold. We were told it was nothing serious, just an adjustment to the Captains seat. Only one update was given while we waited 1.5+ hours for a “SEAT ADJUSTMENT”. Can’t forget to mention that on all of these planes the WiFi only worked on two. During that time at least three others flights in my area announced that they were overbooked and were taking volunteers before bumping people. Another flight to ORD announced a gate change and less than five minutes after announced that they were really not changing and announced for everyone to return to that gate. Can’t forget to mention that on all of these planes the WiFi only worked on two.🤡🤡

Flying on this airline is nothing short of a full blown circus clown show. It is so mismanaged it should not be in business as there is no way it can be safe as badly as it is managed. It is 100% about money and customers be damned.

IT issues created a mess had you change my flight and your system never changed it

The ground closures and flight delays were unwelcome. I think the captain did what he could to manage expectations for the delays, but the stress level increasing in the cabin was palpable with every announcement. It may be obvious to those who fly frequently, but if the ground is closed for us to get to a gate, it's also closed for connecting flights to leave. Other passengers were so stressed they were rude. A bit further explanation could have helped.

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

Passenger was too loud for the entire flight crew not once ask them to tame it …. Many passengers are uncomfortable including having headaches

The Mario was so helpful and provided amazing customer service however l have being waiting for a callback for almost a week now and have not heard anything further after l informed them l wanted to change my date of traveling because of my hospital appointment even send them proof and l was unable to use manag your booking on their website is a bit frustrating and l would appreciate an update on My request as soon as possible. And have called them times without numbers no response

There is no room, no gluten free options, or any free internet/entertainment. You have to bring your own tablet or smartphone because there are no screens.

April was the flight attendant in first class and was the most pleasant, cordial and efficient person I have seen on a flight in years. Good example of the type of people AA should hire to increase customer satisfacdtion.

Excellent accommodating crew at gate and on board. Baggage claim and gate checking were flawless.
