Wi Fi was horrible kept cutting out the whole time and too expensive

I really like open seating. I hate that I've heard this is going away. This is one of the unique things that makes Southwest my goto choice.

Boarding was a little late, but made up for it. It was quick to taxi to the runway, since it's a smallish airport.

Excellent! Only question is how we check in at exactly 24 hours in advance and end up at the end of the B boarding group

Multiple delays and gate changes. Arrived at final destination 6 hours late. All rental cars had been taken.

For the first time in a long time we had a flawless experience with Southwest. Both flights were early and no mechanical errors at all. We were shocked and pleasantly surprised 😮.

One of the crew performed a hilarious skit to accompany the standard instructions. Passengers enjoyed it so much they applauded at the end!

It was really nice! I appreciate the gate attendant allowing families with small children to board early on in the process… that was very helpful! The internet service didn’t work with the app I was trying to use even though I paid the $8… other than that it was great! Oh and I should’ve asked for the whole cranberry cocktail can. That cup was about 2 sips…

A bit expensive for the overall service; but the flight departed on time and arrived early.

I love no assigned seats and bags fly free. If Private Equity gets their way and forces Southwest to change they will be everyone else and I will stop being loyal to them. DON'T CHANGE YOUR BUSINESS MODEL!!!

My seat was comfortable. There was no TV on the airplane.

Flight delay was inconvenient and exhausting getting in at 1 am. However the crew and lounge was very comfortable.

Small dirty plane for a 5 and1/2 hr flight. No food no entertainment

On time (in fact, early). Easy boarding and getting off.

All 4 members of my family found the seats terribly uncomfortable. 2 of us suffered from back issues the next few days.

No complaints. Great service. A first class entry lane at boarding wouldn’t hurt.

Plane had a maintenance problem two hours into the flight and we had to turn around. Alaska was nice to put us up in the Hilton in LAX but the cost of food in the city was WAY higher than our vouchers and the hotel had no continental breakfast. We ended up spending over $100 on food for our family in addition to the vouchers.

You an Kayak offered travel insurance. I had to cancel are flights which I well say was easy an I got my money back. BUT not the travel insurance Kayak or X cover has keep the money. So why I never went on the fligt I cancel way early. I know one thing I'll never go to kayak again.

Check-in was easy, I did it from the app. Boarding was easy, the crew was great. Santa Barbara airport had a disabled plane so we had to land in Burbank to refuel. They kept us well informed, and everyone was great. A very entertaining person from the Burbank airport got on and told a few jokes.

I had to miss that flight as my first flight was cancelled in Idaho Falls. Bad day all around . Couldn’t be rebooked!

Seats were really tight and the seat belts did not give enough slack.

I like in St George and prefer to fly out of CDC than SGU. Hopefully, they will continue the flights out of Cedar

Broken jer bridge. Poor communication about it. Lost 2 of 4 luggage pieces

Overall, it was okay. Seat was a little cramped. Would’ve liked more substantial snacks or opportunity to buy some.

Newer plane, relatively easy boarding, not a full flight and was told that we could not be moved up because of weight and balance issues. Otherwise, a very good experience.

Other then mechanical/ computer problem and 3.5 hours flight delay the flight was great. I guess that what happened when you fly an old airplane now a day.

I was with one of the last zones to board. It was kind of annoying to finally get called to board and my whole section was already on the plane. Clearly they boarded with previous zones. So by the time I got on board, there were no spaces for my luggage above my head. I had to put my luggage 4+ rows behind me, which meant that I had to wait even longer to get off the plane, since I had to wait for those rows to clear the aisle before I could retrieve my luggage and exit the plane. This also held up the plane cleaners, as they couldn't service my row until I cleared it, so they were all standing there waiting for me, while I'm standing there waiting for the other passengers to clear the aisle. Anyways, I wasn't in a rush this time, so I just waited, but I could see that being a problem in the future. Now, I could have checked my luggage, of course, but coincidentally, a friend of mine on the same flight got their luggage damaged (wheel completely knocked off) and was told by the Baggage Attendant in the airport that Delta doesn't "cover wheel damage" on luggage. This was disappointing to hear. I'm glad I didn't check mine through. If it were my luggage, I'd be highly frustrated to hear that. It makes me not want to check my luggage in the future.

The dear was very limited in space. I could put my water bottle in seat basket. Also, there was no inflight entertainment in the delta app?

Typically I give delta excellent reviews. Our flight was delayed 2hrs, I was one of the fortunate ones who were able to get to my connecting flight. Also, annoying that on the connecting flight boarding personnel make me put away a small bag into my carryon. It small enough to put in back pocket seat, why hold me and the line up to just push it into my carryon.

Everything was great. Great service, excellent communication, and early arrival

Received an email the night before showing that there would be seatback entertainment on our flight. We get on and there was no seatback entertainment. And then it was a scramble to try to set up the iPads for the kids before takeoff so they could watch something for the four hour flight.

The reason I don’t fly United. No in seat entertainment for a long flight and inconsistent WiFi and entertainment available from my device.

It was a good flight. Nothing comes to mind about how it could have been better. It was a newer plane, seemed like a great upgrade from your older ones. Staff was very good as well.

The food for long haul was poor compared to Singapore airlines economy. Pasta plain with tomato sauce . Singapore airlines give me Hagen dash small ice cream cup it was great. The choices of dinner course Singapore air also much better The crew mostly friendly. The economy seat are as expected.

The plane was clean. The staff was excellent. The flight attendants were very good. Enjoyable flight. Overall. The seats in the back are too small but, will always be.

Flight was 3 1/2 hour delayed with no credit or meal vouchers

late departure due to some unspecified issue with ventilating the cabin. They got it running but it was FREEZING for the whole flight. I asked for a blanket but they didn't provide one. They could not turn up the heat. it was quite miserable.

Liked that we left on time for each flight. Snacks not the best, but we're okay.

It was fine. The flight attendant appeared to be in a bad mood but everything was fine.

The entertainment would not work. The comfort of the seats leaves something to be desired, pretty uncomfortable.

We boarded after several delays due to mechanical failure and a gate change. The seat cushion in the exit row was very compressed and offered no cushion, making the four-hour journey reasonably uncomfortable. The WiFi worked for a few people, but for most, it did not, and you cannot get entertainment unless you can connect—American Airlines flights do not have seatback screens, and you must use your mobile phone.

Terrible. Internet/kiosk glitch prevented baggage checkin. Line at ticket co in Ter was under serviced and did not move. Agents did not call for flight but rather allowed time to pass. Then told each person as they reached the front if line that it was too late to check bags so they’d have to rebook flights. At least 15 people missed the flight as a result of this incompetence.

After several delays and being rebooked onto a layer flight, I had to speak to three AA agents for baggage claim to get an attendant. All were in foul mode and reluctant to assist or offer any assistance.

Only thing that I liked it that I got to my destination safely, otherwise American Airlines stinks.

Improvements in communication and empathy are absolutely necessary for American Airlines staff (top down). It’s like they are numb to the needs of their customers.

You were more on time than United. I'm so over united delays.

Good communication at the gate and very nice crew in the flight

Timely boarding process, made up for lost time even after a lengthy wait for de-icing

My seat was wonky...hard and not much padding. I sat next to the Jumpseat for the flight attendant. Thoroughly enjoyed not have a third seat in that row! Flight attendants were amazing. I couldn't answer the "food quality" question as there is no food served on my short flight. I commend the pilot as I know it was super gusty when we landed. Thanks

Seating was horrible. Small seats. Access to flight information and extras very iser unfriendly. Kept losing internet after paying for it. Staff in madison was as unprofessional and unhelpful.
