I thought I paid for a round trip for carry-on and my ticket only had one way when I purchased a round trip Didn't make sense to me .Not what you want to hear when it's time to go home.

I thought I paid for a round trip for carry-on and my ticket only had one way when I purchased a round trip Didn't make sense to me .Not what you want to hear when it's time to go home.

Support for wheel chair was not good. Desk did not open until 2 hours before takeoff not check in time.

Boarding process was super smooth and the staff and crew were wonderful. Seats made me feel like I was being bent forward. Might be because I'm shorter and the puffy head rest pushes my head down. I would have liked to have been able to remove it

What entertainment!? Snack i bought was unusual and in very small quantity. Very limited selection of snacks to buy. Taste was mediocre.

Flight attendants were wonderful. Seats were comfortable “Nicest” bundle). No screens or meal, but it is a budget airline.

Great experience and In love flying in and out of Provo airport

It was pretty good. Only thing that makes our boarding uncomfortable was, that we had to pass TSA at terminal 1 and after that walk 15 minutes to terminal B, because bus was insufficient to take so many people and waiting time for the bus was more then 1 hour.

Breeze was good but the sandiego airport had traffic and waiting 1 hour in the plane till take off

This was my first time flying your airline and it was okay. The people were nice but I am not used to all the add ons and no movies or even water. But I knew it was going to be that way. I think I prefer paying for the extras to be more comfortable.

Check in was a breeze. Crew was amazing! The two seater had more leg room than the three seater. No snacks available, only for purchase. No internet available, only for higher paying ticket. booking through a third party was misleading - purchased with carry-on, but it did not really come with carry-on.

Southwest has been a nightmare. Delayed flights, missed connections, systems down. Never again am I flying southwest.

I think Southwest is the number one airline that anyone can fly I have flown for the first time Frontier and what a joke and their customer service United was a very strange experience I'm only sticking to Southwest from here on out for sure

3 hour delay. Had to change plans and was still delayed.

As always, the entire Southwest experience was wonderful, from online booking to flight to baggage retrieval. Very grateful.

The weather could have been better. There was a 40 minute ATC delay in SFO because of marine fog and a micro cell storm delayed landing and take-off at Nashville. The gate was changed 5 minutes from boarding from gate B3 to gate C23 at Nashville airport.

The cabin was quiet for the redeye flight. The area was clean. The staff was great. The 787 Max was in good condition. Drawbacks were that the seat widths were tight for some passengers. The seat padding was at best average and for a long flight uncomfortable.

Employees were kind and funny, as always! Flight was late but no announcements were made for people with tight connections to help them transition quickly. No service due to turbulence.

I used to fly SWA all the time. I know the crew has their little acts that are often fun, and entertaining. On this flight one of the crew was just not nice. Very surprising.

The flight was delayed for almost an hour. We sat on the tarmac. There was no announcement. Not by the pilot or the crew. And for some reason, there was no beverage service, so even though it was a short flight, we had sat on the tarmac and the extra hour delay made me understandably thirsty. Water would’ve been nice if they had offered it. And for the first time, I forgot to bring my own water bottle. Reminder to bring your own water bottle because you never know if you’re going to get a beverage.

It was a new plane with larger overhead bins & charging ports at the seats.

WiFi was a major problem and if it does not work on a 4 hour flight then that lowers the overall experience

The Airline Attendant found us in flight and moved us to seats in the front of economy due to the short time we would have to make our connecting flight. We really appreciated it.

Carmen was an absolute delight on the flight staff! Everyone was lovely and made it a very pleasant flight.

Internet connectivity still seems to be touchy on these flights, making it difficult to rely on it for getting work done.

Crew was absolutely fantastic and we’re so welcoming and friendly ❤️

Flight delayed four separate times. I’m now one hour hours late to landing.

The plane was an older model, so it wasn’t as comfortable as others. The flight attendants were not helpful during onboarding. It was a full flight so there was chaos finding space for baggage.

Awesome! On time flight, early arrival, and a complimentary upgrade!

Delta’s staff is unmatched. From the gate agents, to the pilots, to the flight attendants… all top of the industry.

Our flight from SFO to MSP was right on time on 11/15/2025. No delays. As we approached MSP at about 8 pm, we circled in the air until 8:40 pm so I don't call that efficient for MSP. I think the captain should announce the delay and why. (as if we all don't know that we are just circling around the area, slowing down, speeding up, slowing down.) Thank you. Marilyn Fischer

This was an auto-rebook due to being delayed from an earlier UA connecting flight. The boarding was fine, but they sat me in a middle seat when my original booking was a window seat. Overall, the flight was fine as it still got me to my final destination.

Sitting in coach even in the larger leg space is extremely uncomfortable and the staff pay no attention.

It was a short, comfortable flight. It did leave an hour late due to the pilot having to be replaced (family emergency) but that didn’t inconvenience myself & my friend. The situation was explained, eventually.

Lost one piece of luggage even though I checked in 2.5 hours before the flight

Horrifying Almost 2 million miles. Bring your own food and drink. One coffee or drink every three hours. Have to order meals on app more than 24 hours ahead Tiny and dirty bathrooms

My service dog and I were asked to deplane just before they closed the door - clearly very last minute they couldn’t find the documentation that I have filled out many many times before that is for flying service animals. I purposely purchase 3seats (a whole row) since he is large and not all passengers want to sit next to a dog on a cross country flight. The plane departed with my husband on it!!! They made me fill out a hard copy of the same form and had to reschedule me on a later flight where they could find 3 seats together!! I’ve done this so many times before - clearly the error was on their part in a technology glitch - but really people - do better!! Very traumatic - and my husband had to wait for us when he landed ….so bad. Poor pup was confused and tired.

No screens or meal options. Freezing cold. Dirty seats. Left late.

Outstanding service, efficient & friendly crew, flight was safe, comfortable & on time

It was a red-eye, but the flight felt surprisingly quick. The seats were very comfortable, and that made resting much easier. I also want to thank the gentleman seated next to me, who graciously moved so my mom could sit beside me. We slept almost the entire way. The cabin crew was respectful in not disturbing us, while also being courteous and professional throughout. Thank you, United.

Boarding was again a "free for all". We were boarding group 4, and almost the entire plane was able to board before us. It's a shame that someone who follows the rules, gets the short end of the stick. Not fair.

Little communication with passengers after sitting over 1 hour for a maintenance issue Then we had to deplane- no crew communication Poor gate information after deplaned WiFi would not connect AT ALL

Flight attendant made the flight very enjoyable. He was courteous and gave great care to the passengers

Not good. Flight crew, was not friendly and just shoved stuff at us. Not the way I like to travel.

Aside from the little delay, overall was flight good. Made it safely. Thanks!

Over the course of 7 months of travel, I can count on my hand the number of times the flight has departed on time. Majority of the instances have been related to non-weather reasons. Would not recommend flying this Airline

The plane was spartan, the seats not that comfortable. It was like flying a super low budget airline. They charged for coffee!!! I have never, ever experienced that before.

I had no problems but the changing of planes that I was supposed to be on was confusing. Maybe it would be helpful to let people know your flight changed. Not everyone understands airports or how flying works.

Flight was delayed multiple times without giving any particular reason and the only thing that was communicated was that 'Aircraft is getting ready'. I was stuck at SFO airport for 15 hours and finally took Southwest Airlines flight back home to Dallas.

I was not clear if food was offered or not.

Agency very bad had to cancelled my booking too many changes in the flight changed my flight to 1 week
