Southwest is kind of a slum airline. It’s gotten more expensive over the years for less and less service. I am a Southwest Chase Visa card holder and was forced to choose a seat in the 26th row in the middle seat. However my wife who is a rewards member but doesn’t hold a card or anything else, gets randomly assigned a normally paid seat in row 6! How does that work?

Southwest is kind of a slum airline. It’s gotten more expensive over the years for less and less service. I am a Southwest Chase Visa card holder and was forced to choose a seat in the 26th row in the middle seat. However my wife who is a rewards member but doesn’t hold a card or anything else, gets randomly assigned a normally paid seat in row 6! How does that work?

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

The seat was not comfortable. 1D. My back was sore all night and the next day.

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

Great flight from Seattle to Phoenix and to Chicago-Midway from Phoenix

The new boarding process was easy and straightforward. Very pleasant.

The flight was okay. The pilots did an amazing job and kept us updated on the flight. The flight attendants were okay. They found time to be chatty with each other rather than focus on the guests. One of the attendants was a little less warm when asking about my bag I had on my lap that I was using during latter part of the mid- flight. Mind you, it was not the departure descent. I’m respectful to each and every attendant, it was the tone in her voice reminding me to place my carryon bag on the floor. I hope to have a better experience next time.

The entire travel day was a disaster from beginning to end. Woke up at two in the morning to make it to San Juan airport in time for a 5:30 am flight to Milwaukee which connected in Baltimore. Massive delays lead to me missing original connection out of Baltimore. Sixteen hours of delays/rebooking/layover time later, arrived in Milwaukee to find that only one of two checked bags made it there (despite the fact that Southwest brought another 737 jet to San Juan to fly us out to our original Baltimore connection—-not squeezed into another booked flight). The flight from Baltimore to Milwaukee was barely half full, so there was no logical reason to ship my bags out of Baltimore on a different flight to Chicago to then ship to Milwaukee. Southwest decided that my bags should not have been on the same connecting flight I WAS ON to Milwaukee, and then proceeded to accidentally leave my larger bag with the important items in Chicago. Terrible logic and support all around. Extremely angered and disappointed with SW. What a clownish operation your company has become!

It was as expected and I was grateful for the wheel chair help and ease of use.

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

Everything went smoothly, although the usual gripes about airline travel were still present: the boarding process is inefficient, the snack selection is limited, and so on. Since there was extra space on the flight, the gate agent rearranged many people's seats to put people on the aisles and windows, leaving the middle seats empty, as much as possible, which was pretty great.

Landed without a gate ready. Plane is extremely old and dirty.

All the amenities was wonderful, if they could keep their prices that low. I'd fly with them all the time.

Very old plane with no inflight entertainment. I purchased the internet pass and it was nearly unusable.

My tray was broken so i had no place to work or eat except my lap. Flight attendant said I would get an email with some credit or miles, it was a complete waste of time as I could only function at about 20% of normal. I have not received anything yet.

Short trip, no food and therefore no expectation for much interaction with staff who were pleasant and professional. My critique is on comfort of the seats. Exit rows and comfort seats do not provide enough personal space for 3 side-by-side seats, especially when in the middle row. Some passengers are not considerate of the middle seat and there should be signs that state something to the effect of: "please consider giving middle seats use of the armrests."

My flight yesterday evening was delayed 3.5 hours with no water or food service. Poor experience

Transparency from pilots, quick boarding and exiting the plane, staff greeted to each and everyone,

Didn't like sitting on the waiting pad for 30 minutes right after departing the gate. If you're going to do that, just don't board so people can still get up and walk around in the terminal. My luggage was damaged by the baggage handlers.

Pilots lied about waiting on “paperwork”. Sat in the plane for over an hour, waiting on some papers to be printed according to the pilot and then all of a sudden he says good news maintenance is finally on their way. Maybe they can fix it before we get our paperwork. Ended up missing my connection in LaGuardia and as a result, had a fly home to Lexington instead of the Louisville airport. Then paid $100 to uber to Louisville since it was midnight by the time I got in. I wish they would just be transparent with passengers sometimes and not try to beat around the bush on why things are delayed.

Every staff member was professional, friendly and courteous. The pizza twist was ok. It was warm but too much dough.

Wonderful in-seat entertainment with seatback screens and huge selection of quality movies. The ability to bluetooth connect headphones was amazing.

Flight left on time and we arrived 25 minutes early! There was a gate available when we arrived so early on a busy Sunday afternoon! Flight attendants came around twice with the drinks cart.

Sitting on the runway after we land for almost two hours! Not sure if we should blame United or Just Dumpy Vance.

Flight was late - I was downgraded from first class to coach

Crew seemed a bit cranky. No seatback screens. But boarding was efficient and on time and we arrived early.

See previous note about the passenger in Denver who threw my husband's bag out of the overhead bin in order to maker room for his own. And the flight attendant back up the new passenger.

Terrible. They wouldn't allow me on my flight on the 14th..

Impressed with the service despite turbulence because of the weather. Both flights arrived before their scheduled times.

Great experience…left a bit behind schedule but made up fir that in the air and landed 10 minutes early 😁

Flight: Started on time. Comfortable flight. Arrived on time. Crew: Very cordial and helpful. Drinks and snack was served with a smile. Overall enjoyed the trip. Regards, Hari Doss Chanchala Doss

It was good, the staff was great, and the food, was as usual, tea and biscuit. Bathroom was clean, and the plane was clean as well.

Early departure meant on time arrival. Only real problem was free internet had issues, although chatting with the internet help desk (you can do this via aainflight.com) got the issue resolved.

It was really a terrific experience both going and returning on AA. Staff and crew were professional.

Flights on time w/o delays. However, my baggage was damaged. Ground crew, throws baggage from plane to the baggage carrier, carelessly.

This short sector between Miami and JFK was undertaken purely for business purposes, with efficiency as the primary objective rather than a full inflight experience. Overall, the journey met its intended purpose; however, the ground experience at Miami stood out significantly. During check-in, I was unable to link my frequent flyer details from Qatar Airways (oneworld alliance) through either the self-service kiosk or web check-in. The situation was handled exceptionally well by the check-in agent, who demonstrated remarkable ownership. She coordinated across multiple counters, ensured my frequent flyer number was correctly reflected, reissued the boarding pass, and confirmed that mileage accrual would be recognized. Additionally, she ensured the boarding pass reflected priority status, enabling a seamless priority check-in experience without delays. This level of proactive service was both commendable and impactful. Boarding and the inflight experience, operated by American Airlines under a codeshare arrangement, were efficient but largely transactional. While operational delivery was smooth, there was no visible recognition of oneworld frequent flyer status onboard. In comparison to the consistently personalized engagement typically experienced with Qatar Airways, this absence was noticeable—though understandably a potential limitation of codeshare alignment rather than a direct service shortfall. In summary, while the flight itself fulfilled its operational intent, the exceptional professionalism and commitment demonstrated at the Miami check-in counter was the defining highlight of this journey. Greater consistency in elite recognition across partner airlines would further enhance the overall experience.

I was able to get the AA customer Service desk to put me on an earlier flight without any issues.

The seat was comfortable, the attendants were very nice and WiFi made my life so much easier with work. Kudos!

Flight was 3 hours delayed. They gave our plan to two other routes. Need to knock that off.

To have arrived on time and not 3 hours late after having already spent $100 to change to an earlier flight, only to arrive back home close to the original flight time.

They didn’t offer a water, even after I asked

They switched our terminal 3 times and we were delayed for four plus hours!!!

It was an early flight and most people napped/slept and the crew let us which was nice.

The crew acted like they had never done this and kept barking passive aggressive orders at people. + the security line + the delay + sitting on the tarmac for 2 hours + none of the apps or signage updating with correct times

More inflight connection. And leg space is horrible. And the paying for baggage I'd ridiculous!!!

My flight was originally from SAT to MCO connecting from MCO to ORD. We got diverted to ATL and than Frontier staff there was sooo un helpful first they said they couldn’t give us any accommodation since our flight first got delayed that cancelled and now it’s 221am and I am still in ATL since they said they need to create a new flight my final destination is ORD and I have been delayed twice and cancelled. With no real help the frontier app didn’t work no email updates over all such a horrible experience

There's no seats that lean back with little leg space i wad uncomfortable the entire flight. Your charges for extra baggage is despicable and costly!!

Remind customers of the need to have passport or new ID for boarding.

Flight was canceled. Most upsetting was message from Kayak, stating that the flight was canceled and click with Kayak for details regarding rebook, refund details. THERE'S NO INFORMATION PROVIDED BY KAYAK EXCEPT THAT FLIGHT IS CANCELED. AND NOW THIS SURVEY TO FIND OUT HOW WAS THE FLIGHT !!!!!!!

The flight never took off and we spent 7 hours at the airport
