Boarded on time but once we were ready for take off, the crew determined that, although every seat was taken, somehow someone was on the wrong flight. Delay, delay delay, announcements and ended up with one person checking EVERY ID against their passenger Manifest only to figure out it was a "clerical error." We departed 54 minutes late causing me to run in the St. Louis Airport to make my connection and lose the priority boarding spot I had paid for. Unnecessary delay.

Excellent. Would encourage Southwest to keep current boarding procedures with free style seating. Makes for a fantastic experience

AC sub par. WiFi not working correctly. Ac sucked. Seats very narrow.

southwest just starting charging for luggage. hadnt realized it until it was too late. now out $70 when i couldve bought a carry on if i wouldve known. free bags was one of the only reasons i chose southwest over another airline (the other being no assigned seats, which is apparently also being changed). stupid business decision. wont be flying southwest anymore.

Worst experience I had on Southwest. Still better than most, but the seating was barely tolerable.

It was okay. The plane was delayed from earlier in the day, but they kept updating the departure time, sometimes later, sometimes earlier. That was stressful. Once we finally got on and took off, it was fine. I was supposed to have a connection in Chicago to Los Angeles, and the time for so late I was rebooked to arrive in LA 3 hours late. The departure time to Chicago later became early enough to have taken my original connection and arrive earlier but that wasn't an option.

Everything was on time. I was disappointed by the front section female, African American flight attendant. I did not see her name tag or would have identified by name not race. As passengers moved to the bathroom early in flight, she would say with a disdainful tone “I have to say the seat belt light is on” then go back to her book. Better trained flight attendants say something like be careful the seat belt light is on.

Flight crew and cabin crew were great. I had to rearrange flights because my original flight was 3hrs delayed for weather, the rub is the flight I moved to boarded on time then we sat at the gate for 2 hours because scheduling stole our first officer for another flight, TWICE. Then our actual FO was an hour delayed. To make it worse my original flight went from a 3 hour delay to departing 15min EARLY. Just poor scheduling operations all around.

Bring back peanuts Take our drink orders when were all seated, especially after you switch to assigned seating.

I’ve always loved Southwest. No issues at all. I was flying standby and the gate agent was extremely friendly and helpful. Boarding was smooth and I was able to get a window seat in the emergency exit row. Crew was fantastic! They were very professional and accommodating. We had to divert from our destination due to weather but the flight crew kept everyone at ease and informed us of all pertinent information. Excellent flight

Flight was delayed only slightly before takeoff due to traffic control. However, the flight arrived early to ORD. Good flight. United has been very reliable for me.

Another delayed flight. When the delays exceed the duration of the flight, it’s a problem.

After boarding the plane in Chicago, the passengers were told that there was a technical problem with the plane. Passengers remained on the plane as they tried to fix the problem. After what was probably an hour passengers were told that there was a need to change planes as the problem was not solved. Passengers disembarked and boarded another plane. After taxing to the runway and waiting for takeoff, passengers were told that owing to the thunderstorm the flight was unable to take off but would try and reroute. After some time passengers were told there wasn't enough fuel for the new route and the plane had to return to the gate for additional fuel. after another log delay the flight got underway. On the plane there was food, drinks, ice or entertainment. We were a glass of water, which appeared rationed. Flight arrived about 5 hours late. The pilot was fantastic and communicated with the passengers throughout the ordeal.

Better WiFi. I cannot understand that in 2025, United is so behind on a technology that is now a necessity and still painfully unreliable, slow and keeps disconnecting.

Trip was great. A wild landing in Ottawa with the wind and rain, but the pilot did a great job. Always love flying United.👍

Excellent experience. Starting with the agent at the Premier bag drop who noticed I was very early for my scheduled flight and offered to rebook me on an earlier flight with my seat preference. She would not let me leave the counter until she knew that all of the changes and new boarding pass showed up on my United app. At the gate, the flight boarded quickly such that we departed early and the flight was smooth. We arrived 20 minutes early at ORD and I was able to be home in time for dinner. One of the best flights I've had.

Salina to travers city was great! But the sept 24 Tranverse city was not! Traverse city to chichago was cancelled, i went to Denver & got to Salina 6 hours later!

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.

Flight attendant in first class gave poor service (like he didn't want to be there) and food was awful. We sat waiting for gate upon arrival over 45 mins.

Weather delay in Chicago?. No sense of urgency to make connection in Chicago for our connecting flight that wasn't delayed. Connection was missed.

Flight was delayed leaving Dallas. Arrived about 2 hours later than scheduled.

The only thing to like was that we eventually got to our destination

Poor seat in rear of aircraft Food at Admiral’s Club Terminal D at DFW inedible

We were delayed for a “couple of maintenance issues.” They were resolved rather quickly but a computer glitch caused someone in the airport to have to bring a physical copy of the paperwork so we could leave. I don’t know where they had to drive from to get to our plane but it took forever & we were 1 1/2 hrs late in leaving. The flight itself was fine.

We didn't take off until an hour after we boarded.

The flight was fine. This survey is not. There is no option for N/A so items which don’t apply to my experience still must be rated. In those instances I give a “3” rating which ultimately skews the results.

The actual trip was fine, however, the changes made to our flights and the layovers were had to endure were awful.

Flight from Dallas to OKC was good, but my trip was interrupted due to a delayed flight from Austin to DFW, which happens all the time. I frequently miss my connection from DFW and American can never seem to make this work!

Because the plane was 90 degrees F, they would not let us board. I wish they had, because it meant we were delayed. It's Texas, of course it's hot. We would have survived.

Wish they had the seat-back video screens for watching movies or playing games.

Excellent experience when I am looking for a budget airline where the main expectation is getting me from point A to point B with no frills.

Had to deplane for undisclosed mechanical issue. Landed in Chicago 3 hours late. Food voucher at FLL came just as we were recording. Crew and agents were troopers--better than Spirit last night.

We spent 5 1/2 hours at Ohare cause our flight was diverted cause of rain in the area. We missed appts that we had set on Tuesday and cause we were flying back the next day on the 7am flight we had no time to reschedule anything. Other airlines were landing and taking off fine having no issues. It was only Spirit. Very frustrating flight and I understand why the flights are only around 25-30% full.

Just total easy flight experience!! What could you do better..? Hmmm..? There was nothing I can remember. Spirit was a far more comfortable and easy process than American, United & Delta. I'll always look for Spirit and I've told a few people about, since flying this past trip!! I'm a SPIRIT FAN!! Thank You, SPIRIT AIRLINES!! Very, VERY well done, 100%!! See you...SOON!! -Best, Linda R.

Spirit is a very uncomfortable travel experience. It’s cheap but you are squeezed into the seats like canned meat.

The seat belt was lengthy enough that I did not need an extender. Courteous and helpful flight attendants.

As expected. Nothing jumps out at me as bad or wrong, but the flight was fine. No complaints with pilot or crew. The flight left on time and arrived earlier than stated. Overall, I will continue to plan on flying with Spirit.

Horrible considering I didn’t go and I bought travel insurance and I didn’t receive a refund.

Great! We boarded on time! Everything went so smoothly! The flight was so smooth

Seats uncomfortable, hard to check luggage, etc. It was like the last flight out of Hanoi

Terrible. The canceled my entire flight when I requested a refund for a trip frontier canceled trip one way.

Boarding was on time and plane departed as scheduled. There are obviously no amenities (food, drink, entertainment) on Frontier, but there also didn't seem to be any issues with luggage space either.

Inbound plane was on time and flight departed on time with no issues while boarding.

I knew going into this that Frontier, being a low cost carrier, would be pretty bare bones and charge for most extras but this was made up for by the fact that the airplane was a reasonably new Airbus, every employee was great and best of all, Everett Washington is an amazing airport - thanks Frontier for flying there!!!

i was unable to check in the flight. refund requested

It was well done. It was my first time flying with them and I was nervous b/c I have heard of many cancelled and/or delray flights. Everything went smoothly.

Just know that everything, and I mean everything is “ala cart”. 60$ just to put something in the overhead bin. I will never fly Frontier again nor do I recommend them to anyone else.

The single worst check in experience I could imagine. I’ll never do any business with Frontier or any affiliated company

Too many extra fees, uncomfortable, little leg room. Will not recommend this airline.

Everyone seemed to be in zone 1 for boarding. Maybe break it up a little. Otherwise, smooth flight.
