Overall good, just screaming kids in the area the whole flight.

My experience will Southwest was good. I wish there was more entertainment and the boarding process was slow at time but other than that my experience was great definitely will be flying with SouthWest again.

Flight was delayed by 2 hours, meaning that a flight to Dwnver which should have arrived at 11pm came into the airport at 1 am. Made for a very long day.

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

Great job! My family doesnt fly often but we felt safe 100%

Great job Southwest! My family doesn't fly often but we felt safe the whole time.

SW can't get their wifi right. I upgrade to insure wifi service but the last two trips had intermittent service. Not worth the extra costs.

The flight was late. The crew was rude. There was no food. Cramped and uncomfortable. Nothing about this flight was good.

Crew was rude, flight was late, wifi didn't work, no food, basically nothing about this flight was good.

It was just okay, no frills, basic transportation with no luxury. No screens on the seats, no water or drinks on a short flight. Full flight but at least it was on time.

The seats are too small/crowded. It is frustrating to be forced to sit with someone who is overweight as they crown the other seat. Nothing against the person…just the airline companies who continue(over decades!)to reduce seat sizes. Americans are fat. Those of us who are not are tired of being compromised by the airline companies who don’t faces that fact and make adjustments. Maybe have “overweight seats”? Maybe give us a discount for being forced into an uncomfortable flight due to others overweightness? Please, make adjustments…be accountable. Thanks!

The crew was great and everything went smoothly coming and going.

No outlets, plugs, way to charge the phone or service and no food on one leg o the trip, but other than that, great. Loved WIFI, the flight, the crew, the pilots, the schedule, etc. Great job. My new favorite airline!

Wonderful as always! Pleasant staff, smooth ride, and timely departure.

Flight was scheduled to leave at 6a and delayed for 5 hours due to “mechanical” issues. Everyone else on the flight received an email voucher for $24 of food for the delay, except for our group. Also the carry on luggage bins were full and the crew requested that everyone to pass their carry ons back up to the front while everyone was still standing. They gave no other direction and kept rushing the process. After all bags were sent up, they then asked for seat #s to go with each bag… They should have probably had everyone get to their sits and then pass the bags up in a controlled process.

From Las Vegas to Boise all went well. However, our flight was delayed in Boise and I missed my connecting flight from Seattle to Pasco. Moreover, the last flight to Pasco was full and I was booked on the 11:30 flight Sunday and given a hotel accommodation. However, I was scheduled to deliver the Sunday morning service at my church and needed to arrive no later than 10:00. Therefore, I booked a Delta flight scheduled to arrive in Pasco at 23:09. My piece of luggage checked in Las Vegas arrived in Pasco earlier today. I waited at the airport for over an hour last night to speak with an Alaska agent to no avail. I went back after church this morning in search of my piece of luggage and it could not be located. After waiting for 40 minutes to speak to the agent authorized to take my claim, he announced that he was closing the counter to assist on the flight line but not before providing me with a telephone number that would help me with filing my claim. Before I was able to make the call (due to other factors) I received a call from Alaska agent informing me that my luggage had just arrived and I am now waiting for it to be delivered. I deliberately took the more complicated route home to ensure that I would be home in plenty of time to prepare for myself for the Sunday service and accommodate my relatives’ needs. I believe the airport is undermanned given the number of flights coming in and going out. It was fiasco last night with three flights waiting for luggage and another flight landing within minutes. Today’s problems stemmed from a lack of cross training and a serious amount of cargo/baggage going out and too few people scheduled to cover.

The seats were not very comfortable and there were no TV screens. Boarding was pretty fast because there were so few people on such a small plane and I appreciated that they still gave us our snack and drinks, however I really wish they would come up with a good gluten-free snack.

Flight crew and flight were good. But it departed two hours late.

Pretzels are always a disappointment. Cheezits, Sun Chips, trail mix, anything else would be nice.

They were friendly, efficient and got our bags to us so fast at the end of the flight.

We never made it on this flight because we missed our connection due to o delayed flight from Jackson.

We had a terrible experience. The flight was delayed several hours, so we missed our connection. We were told to wait at the airport. At around 11:00 pm, the flight was cancelled. There were no available seats out of Jackson for the next two days. Fortunately, we had the foresight to rebook on United for the next day. However, we had to spend a long day at the airport and an overnight at a mediocre hotel. It was a miserable way to spend part of our vacation. We also sacrificed our $450 deposit on our California hotel because we could not get there.

delta wifi wouldn’t work boarding was not in sequence flight crew spent most of their time on the phone with the lights off pretending no one wanted or needed anything

Friendly flight attendant Quick checking for baggage drop Quick TSA lines

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

We got stuck on the tarmac taxiing after landing early so we didn’t get off the plane until an hour later than we thought we would

It was okay. We were delayed for weather reasons, but the pilots and the flight control staff figured a way around the storm and were able to get us to Los Angeles safely. Not all the staff members were polite, but the entertainment on the flight was good.

So terrible. My flight was 4 hours delayed and we weren't notified til last second within an hour of boarding. WE had to sit on the plane for 4 hours. ridiculous.

Missed the Flight from Atlanta to Roanoke due to initial flight from Houston being 2hr. late. Now waiting 17hrs. till my first available flight.

Having to up charge for a seat assignment is not good. Delta can do better

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.

Flight was delayed “due to earlier delays of that plane”, so we were nearly three hours late.

There was a piece of plastic baked into my buttermilk biscuit! I have a pictures. The flight attendants in first class were really apologetic, and tried to rectify the situation. I I am very appreciative that they were able to give me some packets of pretzels and gummy bears. I understand they don't personally handle the food until warming it up so I know it wasn't their fault. I don't know whether it was a newer aircraft, or different food packaging, but I was happy that when the food was being warmed up - it didn't smell like plastic. Jokes on me with finding plastic in my food.

The seats were uncomfortable, as if the cushions haven't been switched out in many years. I felt like I was on an old bus. The food was delicious. thank you. Onboard entertainment, very limited. Unless you like violent movies. Why in the world would you have such severely violent movies on a plane? if you don't want to see such things, you don't have a choice. Have you considered that when choosing entertainment? Good god. Why would you have the Godfather? Or black women being brutally beaten with a club? Why in the hell would you put that kind of material on a plane? As for Kayak: Why when I ordered Qantas, was the plane on United?

The head rest is too big and cannot be placed differently/removed. Causes one head to tilt forward and increase back pain

It was terribly delayed with zero support from united airlines. I reached at 1 am in the night. They did not provide any option to change the flights.

It was great. All the crew were professional and nice.

Flight was delayed 14 hours due to DC air show and weather. Missed connection to MUC.

UA594 was delayed multiple times. I ended up getting picked up so I can make it in time for work 6AM on Monday, 7/6/2026

My original flight was cancelled and that affected my trip and my plans and I got no compensation and customer service was hard to reach as well

I will never but. through kayak again. and American Airlines. I will never fly again on. They're both thieves.

It’s love good long way travel!! I always want more give me price down i want ever month travel I miss travel only North Carolina to Thailand in my love her !!

The departure and arrival was on time. The fact that I could load my boarding tickets on the American airlines app.

My flight was 4 hours delayed on departure at 6a causing me to miss my connection at DCA. I had to scramble to find a seat home on a later flight and instead of an exit seat, I was in row 30 on a flight getting me home 5 hours later than planned. The AA team on the ground did a fine job. AA continues to run the airline like the passengers are cargo.

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

Efficiency of supporting mechanical teams who changed a wheel on airplane in minutes. So no delay, and pilot made up the lost minutes in flight. Comfortable seat.

Flight attendants and crew were great! This plane was fine. It was clean and everything worked properly. Now, the gate change was not communicated. No text or information. It wasn't far with the gate change but it still changed without any communication. Not sure if this is on American or Kayakl. Also, internet was the worst. I would never have ATT. 3+hr flight and weak internet. I think I watched the commercials to get on at least 6 times. Terrible internet!

Flight was delayed, boarded, sat at the gate for more than 30 minutes, left the gate then waited on the pad for another 30 to 60 minutes then returned to the gate, deboarded and was cancelled... alternative flight was not booked automatically. Waited in line for 30 minutes but fortunately an alternate flight to a different destination was found ... no thanks to the travel agent used by kayak

Flight delays for communication overall not a good experience uncomfortable on the plane. Person in front of me reclined his seat, putting them inches from my lap.

the plane was so hot!! the air-conditioning was barely blowing. The flight was delayed, and we had to sit on the hot plane before take off for an extended amount of time, waiting on international passengers. Would not have been so bad if it was not so hot. They said it would get better after take off, but it did not.
