My return flight was much better than the flight there! I paid for seat to Veagas but not the return. Thankgoodness they assigned me a seat with additional leg room as I have back and leg problems. I really appreciate it. With the flight already being super expensive due to gas prices and having to pay for bags (now) I needed to save some money.

My return flight was much better than the flight there! I paid for seat to Veagas but not the return. Thankgoodness they assigned me a seat with additional leg room as I have back and leg problems. I really appreciate it. With the flight already being super expensive due to gas prices and having to pay for bags (now) I needed to save some money.

Boarding, crew and inflight entertainment was great. Could have better food options for a long flight. Paid money and got a seat with extra leg space but was asked to keep my carry on under the seat in front of me which defeats the purpose of buying a extra space seat.

Your computers were down and took a long time to check baggage

Southwest has lost most of what made it special. The flight attendants all used to seem fun and like they were having fun. Now they seem just miserable. They do NOT seem happy to give you your pretzels and drinks. They stick it in your hand or on your tray like it's an annoyance. They bark safety instructions at you. It's not just this flight but the last few SW flights I've had to SNA and SAN as well and it's not just me. I've informally surveyed my colleagues (business and leisure travelers) and these feelings are consistent. The tickets are similarly priced to other carriers and the seat assignments make boarding slower. The free luggage and free ability to change flights is still a differentiator. You lose that and there's virtually nothing special left.

Flight attendant skipped about 6 rows for drink service. I got a side eye when I asked for a drink - like it was an inconvenience or my mistake. He shouldn't be on a flight if he doesn't like his job and doesn't have customer service first attitude.

They did not fix the wifi that they knew was an issue on an earlier flight. The flight was filled with business people that were clearly frustrated not being able to work. That can’t happen on a 3 1/2 hour flight. Would rather have been delayed a bit.

The WiFi did not work three hours of productivity lost. 15 people from the firm were on the flight. Loss of revenue

Very rude stewardess; there was a senior citizen woman next to me who asked the stewardess for help getting her purse out of the overhead bin, and it was as though she asked the stewardess for $1M . . . . I was shocked how rude that stewardess was. The stewardess also refused to get the senior citizen woman a drink about half way thru the flight, telling her that we were almost landing . . . . that stewardess made my flight (and in particular the flight of the senior citizen next to me) very uncomfortable

Overall good experience...exception: very cold temp in teh cabin.

I always know what to expect from Southwest - friendly crew, on time departures. I like getting free baggage. The app works great and the in-flight entertainment passes the time.

Quinoa chocolate cookies are my favorite! Would be nice to have internet service like American

Old plane, no amenities. Very abrupt landing. Unnecessarily long taxi time.

The plane left over an hour late. I missed my connection going to Tokyo. They haven’t sent my bag to Thailand, where I ended up. It took me over 32 hours to get here. Very bad experience so far. I hope they can fix this and get my bag to me, within 24 hours it doesn’t look good at this time.

We had to wait almost an hour for the wheelchair porter to be ready to pick up my mother. And when she arrived in Newark airport the porter was not there and she started walking with her cane and her poor mobility. When the Newark porter found her they didn't want to transfer her bags to the wheelchair for her.

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

The plane was so gross and dirty. Literally saw dust layering and flowing out the grey vents. Dust was all over the air vent knobs to the point where I took my sani wipe and cleaned them down so at least it wasn't blowing my my face. Also, I upgraded and paid for Wifi and it's always so spotty. I get we are in the air, but don't charge for it if it's not going to work. I expect so much more from United. They really are giving up.

Too many canceled flights and kept my wife and I separated on alternate flights. We did not fly out of Denver. We paid a lot of money for the seats we wanted and now that money is gone and we did not sit together. That being said, the many agents were very friendly and did everything possible to help us.

It was soooo hot I was sweating even at altitude. I know you want people to sleep, but keeping it that hot is stupid!

Nothing bad to say about the actual crew or airline. It was nice to have a complimentary FULL can of soda, as well as a snack. Blankets and earbuds were also provided at no cost for this red eye flight. I especially appreciated the free WiFi and movie selection with the Bluetooth option. It helped the flight pass more quickly. No matter who you fly, boarding and disembarking are always SUCH a pain. As I mentioned, this is on the passengers and not the crew!!

You can not pay credit Card for purchase Of food in airplane

The price was the only good thing about this flight. It was scary during takeoff when the plane tilted side to side. It made me feel very nervous as I have never had a take-off that unsmooth. There was no on-flight movie or music options and the only complimentary option was water. Other airlines offer trail mix or a caramel cookie and pop options as complimentary. This flight was a 2.5 hour flight. I understand for shorter flights not having options, but a flight 2 hours or longer should offer more complimentary options and in flight entertainment. Also the seats did not recline and for a longer flight reclining seats are a must for comfort.

It was cold on the flight. The crew was very pleasant. I didn't order any food. We were delayed due to Captain waiting on maintenance log. He kept us informed though. The flight itself was smooth. I would definitely fly with Allegiant again!

There is not one likable thing about this airline. It’s starts with the deceptive pricing and continues through the whole flight. The worst staff I’ve ever experienced way over priced bags absolutely no food or drink (unacceptable and you should be embarrassed) the seats are cramped and uncomfortable there is no entertainment there is nothing about this trash airline that constitutes any amount of money. It’s worse than spirit and way more expensive it is disgraceful. Do not travel with Allegiant I repeat do not bother no matter what they say the price is it is never ever going to be the right choice I’m mind blown at how awful the entire experience was I’m embarrassed that I chose so poorly I cannot reiterate enough how beyond horrible this company and its staff are, not one person on this flight or at the airport is qualified to sweep up trash on a city sidewalk they should certainly never be given any job that requires a brain or manners or communication with human beings, what a disgrace to the human race. Your criminal chiselers and should be put out to pasture

Great flight. Friendly staff. Free snacks and drinks would be nice. I would love fewer taxes and fees added on.

My 90 year old father flew with me. He needed wheel chair assistance and is nearly deaf. The staff was amazing with him.

I liked how when I got on board how fast we ended up taking off but what I truly disliked was how uncomfortable the seats were. There was truly never a time that I could ever get comfortable during both of my flights. The seats could get away during shorter flights but flights 3 hour plus makes it hard to enjoy.

Good, but a bit late on take off after loading. Don't like charging for carry ons!

They boarded passengers that sat in the back of the plane first, making boarding very efficient.

The flight was delayed 6 hours and we were only offered an $8 food credit. My husband stood in line to get the credit for 45 minutes and when he got close to the end of the line the computers went down.

A foot rest for short legged people and a complimentary water would be nice.

The now boarding notification was not updated in the app until I was actually on the plan. This si a massive fail considering my flight was delayed several times. These types of failures add stress that could be avoided since I no longer feel comfortable leaving the boarding area to get food or visit a lounge. Had I used the notification from the app, I would have missed my flight. The secondly, the process of connecting to wifi on aa flights is clunky and could be streamlined better. the copy and past process feels like MVP, and you are well beyond that stage.

The crew in the Vegas airport clearly was having a bad day … they moved on and the crew that checked us in for boarding was great, as was the flight crew. I did get the wheel of my carry on stuck in the overhead bin. Amazing team effort to include the flight attendants, the pilot, and another pilot who was on the flight as a passenger. Finally got it unstuck ✅

My seat was defective. The suppor was broken under the cushion so I road on metal for 4 hours

I always looks forward to the Biscoff cookies and they weren’t offered….

Inflight wifi was awful. Couldn't connect for the first hour until they manually reset, and after that the connection kept dropping every five minutes. Their entertainment option streamed fine but normal browsing was unusable.

weather delay of almost 2 hours then we landed and our gate wasn't available so we waited another 30 min

We got delayed getting out of DFW for broken overhead bins. Once the flight got underway the captain kept the seatbelt sign lit the entire flight despite little perceptible turbulence, preventing use of the rest rooms and any sort of refreshment service in the main cabin.

It's very confusing because Kayak has it as American Airlines, but it was Hawaiian Airlines, but operated by Alaska Airlines. I had to go to the airport for my boarding pass because American said I didn't have any trips.

The boarding was pretty easy. However, the first class seats are not lay flat as other airlines (like JetBlue) has and therefore sleeping was a challenge.

It was freezing in there. When I asked about it, the response is “we would have to tell them” and then she just walked away and continued to serve beverages. Everyone was cold and they didn’t care at all.

Did not get on the flight, they had a gate change and my app never updated me! Trying to get flight credit

Tiny seats, no entertainment, no amenities, delays, they charge for carry on and their allowed personal item is smaller than in other airlines.

Frontier.. nickel and dime add-ons. Flight late, on time, late again, last minute gate change, arrival gate required a shuttle to the terminal. They sure keep you guessing.. if you like a little chaos and airport anxiety, this is the airline for you!

baggage clamed had to wait over a hour and half for all people on my flight it was terrible

Both legs of the flight were changed. The day of the flight and length of the trip.

First of all, we never got on the connecting flight to Denver. They delayed our flight for two hours. If we would have gotten on that flight, we would have been stuck in Denver for 13 hours. So we re- routed our flight for a straight through flight to Oklahoma two days later. THEN, they delayed that flight for two hours. After that we were able to finally get on our flight and come home. Frontier Airlines - one of the worst airlines I have ever been on.

The worst flight of my life. Never will I fly frontier again

The plane was comfortable. The time to board was way too slow and very unorganized! The crew was not as friendly as normally. The was not a single time that they offered water nor anything!!!

This was a full flight and I was in Zone 1, however upon boarding, several other zones went in ahead of me, leaving no overhead cabin space near my seat. This created a challenging disembarkment process.

food not having to pay for it, reclining seat would be nice, more leg room, HEAT!!!!!!!
