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

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.

Luggage was intact and arrived at the destination. What more could you ask for.. haha. The delay in arrival wasn’t SW fault.. just selfish passengers not wanting to check their luggage knowing they were in the last boarding groups

Low cost, but I think I really wanted an aisle seat, and I could not easily get one. The return leg might be easier.

Trip from SNA to SFO and back was riddled with DELAYS.

Flight there was massively delayed but never updated on the app. Flight home was massively delayed but also never reported until after we arrived at the airport.

Gate agent and flight crew were amazing! Only issue was landing and waiting on the run way for 30 mins to deplane.

It was all a wonderful experience. I hate to fly and I hate to travel yet. This was a very pleasurable event. Thank you.

Flight cancelled originally with no email informing me of the change. Rebooked for the next day and that flight was delayed with no update on the app.

Sat next to toilet after booking with kayak. Last seat last row

Poor transfer conditions at LAX almost missed flight. Long walk and delayed shuttle ..avoid at all costs

The plane was freezing. A few other customers mentioned how they can’t get their temperature right on their flights lately.

The food was fine, I was in economy so wasn’t expecting more. Would have liked an entree like pasta/lasagna. Entertainment/movies were ok. I have Apple TV & HBO so I was searching for new releases. But these are just my preferences for food & entertainment. The flight was good. I like the design of your seat backs/tray tables with the extra cup holder and screen holders

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

Excellent flight, the planes were newer, they did a nice job with boarding, great service overall.

Thank you for not flipping the plane on the run way. You guys get a 5 star rating for the flight!!!

Boarding is, as it always is… horrible. Gate lice. Slow moving zones. Too many people with carry ons

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.

Please please take consideration when setting cabin temperature. The vents were not functional and it was over 70 degrees in the cabin during the winter months when most people are used to much cooler indoor temperatures. I was down to my white t-shirt and the sweat pants I wore from Auckland to San Francisco and was sweating profusely and there was NO VENT!
