Flight was awfully bumpy and landing was a bit jolting. I was in the restroom when snacks and drinks were served and was not asked if i wanted any. I had to ask for water finally.

Flight was awfully bumpy and landing was a bit jolting. I was in the restroom when snacks and drinks were served and was not asked if i wanted any. I had to ask for water finally.

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

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!!!

Crew was great, flight was uneventful (which is what you want!), would like media in the seat backs in all airplanes ..but all in all it was a good flight experience.

Unfortunately, an issue occurred where a delay impeded me from making my connection in LA. I couldn't get a flight home until 10 hours after my originally scheduled flight. Once I finally made it to DFW for my connecting flight, my next flight was delayed. I was supposed to be home on 12/23 at 9:00 p.m. I didn't make it home until 12/24 at 11:00 a.m. I was given the choice to either take a flight the next day or the flight that way 10 hours later. I wasn't given an option for a hotel if I stayed overnight. I was also denied the ability to go to the Alaska Lounge due to the delay. It was a very uncomfortable experience. The only seat I was able to get on the next flight was in a row where the seats couldn't recline. After an extended wait at the airport, this was very frustrating!

Paid for first class, but the flight attendant for first class did the minimum required. She really ever came to pick up the trash, and never asked if we needed anything. Every person had to ring for the flight attendants if they wanted any extra drinks. When I went back to use the restroom, she was just sitting on her phone.

We don't have food or entertainment on this flight. We were late boarding but then arrived in Yakima early. Kayak sent me a delay notice but we weren't delayed.

Nothing! I just didn't eat or use entertainment. I had three seats all to myself and it was wonderful!!!!

The confusion from Alaskan Airlines to American, no one at the front desk of Alaskan told me I didn't have a flight, which made me miss my flight that was transferred over to American TERRIBLE customer service at Alaskan!! American Airlines was a great experience. Alaskan TERRIBLE!

I paid $49 to select my seat---6A a window seat just behind first class. When I started to get on the plane I was told that my seat had been given to someone else and I now had a middle seat. They finally gave me an aisle seat. When I told them I wanted my $49 back, I was told I would need to call alaska and fight with them to get my money back. And when i was on the flight people going by kept hitting me with their bags. I have tried calling alaska twice to talk about a refund but never got thru to the right person!

The kiosk for check in/bag check in. I liked the older version where you did everything on the kiosk (check in and bag tags). This time I needed to use my phone to check in and then scan the ticket from my phone to complete the bag tags. I didn't care for this new method. The older method was simpler.

Flight crew had the courtesy to ask passengers from my first flight to allow those of us disembarking to go first so that we could make it onto our connecting flights. Worked like a charm. Both crew and fellow passengers working together for a better outcome for all.

Weather caused delays, but since I was in no hurry I asked to reschedule for any other day to make room for anyone in need of keeping their schedule. Alaska accommodated my request with an extra bonus - with a credit to my account for another day…. Always had great experience with the Alaska folks.

Great service. Great staff. Boarding was a little slow, but I think there was a service dog slowing things down.

Flight left early and arrived early. the whole trip was excellent.

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?

I liked all the informational texts. I always knew where to go and when .

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.

Paid for a window and was assigned to a middle seat with 2 very large people on each side of me. Flight was sold out and I feel I need to be refunded foe paying for a window seat and being put in a middle one..

The service and food needs to improve to catch up with other international flights

Small plane, so no entertainment. Hour delay! Nobody explained wht the delay was all about.

I wasn’t happy with the hour delay from Dallas to McAllen, but that is the nature of travel. I don’t like to fly in general because of all of the problems all the time.

It went up and down at the right time and place. I’m happy with that outcome.

Staff at the gate were incredibly rude, hostile and threatening. Never fly American Airlines.

Would have been good to have a meal since it was a 5.5 hour flight

Same problems with delays in Dallas. This was weather related and due to the incoming flight being delayed. This was the flight that was delayed due to a missing flashlight which turned out not to be missing.

Most of the delay was due to weather which is not what was at issue here. One delay was due to a missing flashlight and in the end the flashlight was actually found on the plane. The entertainment system is very limited. Live TV options offer only a few channels that are not very appealing. Boarding and deplaning are always difficult. It just takes too much time to get on and off the plane. On the plus side, I missed my connecting flight, but was easily able to book a later flight from the app while enroute.

I had a horrible experience from the time I dropped off my bags until the time I landed. The staff taking the bags at the check-in counter prior to security, forced me to check my baby stroller, even though it weighed less than 20 pounds. their excuse was that the wheels were too big. I have never had an issue gate checking this exact same stroller in the past either on American or on any other airline. when I asked for the agent to show me the rule about the size of the wheels on strollers, they told me to look it up on the AA website. I did so, and did not find any indication that wheel size was a problem for gate checking strollers. The only limitation would be the weight of the stroller which mine was below. I was left with a one-year-old child and all of my carry-on luggage, diaper bag, and the like to walk around the airport without the assistance of a stroller and had the same issue when I exited the plane and had to go all the way to baggage claim without a stroller. In addition, while on the airplane, I was told I can only get one bag of cookies as a snack, even though I was with a child. Apparently my child and I were supposed to share a cookie. While this latter issue is a minor one, it is just another example of the absolutely horrible customer service that American Airlines provides. In addition, the 737 aircraft that I was on was extremely hot and the air vents above the seat were so far away from the aisle and middle seats that it was comical. I could barely reach the air vent to adjust it. I had to ask the person in the window seat to do it for me. The whole experience was just a nightmare.
