It’s too cold like fridge and they don’t offer a blanket with expensive price

A List preferred boarding was nice Asked for a mask and cheerfully received Denver bag check-in is tricky. Not near other checking desk. Have to navigate to east security and up to level six for bag checkin. TSA busy and 20 minutes process thru pre lines Denver train to gates quick but one more thing to plan time for and long concourse walk to gate

Not exactly Southwest’s problem, but the new Burbank airport is not great. No restaurants open and tons of work still to be completed. Can’t believe they opened the airport in that condition.

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.

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

I liked how it boarded fast. I do not like how the seats are just too narrow, and I’m not a big person.

Despite paying for an ‘upgraded’ seat in row 1, I had to put my luggage in the middle of the plane. Snacks were bleh and seat was small and uncomfortable and I am not large. Attendants were fine but not super helpful. Plane just seemed outdated.

Delayed for no reason at all originally. Then they said it was due to weather conditions. Communication between kayak and Southwest was terrible because both displayed different delays and departure times for HOURS throughout the day. The plane then had technical issues which delayed us from taking off even longer. Didn’t actually take off until 11:45pm when the original departure time was 7:35pm. I didn’t get home until 1:30am the next day. I was exhausted and pissed off. I am not confident if I’ll fly southwest in the future or use kayak to book.

Flight was fine. Only thing was flight was delayed nearly 2 hours. Flight was originally scheduled to depart at 7:50pm but didn't depart until 9:50pm. I got home around midnight. It was later than desired and I had to get up early next day to take kids to practice. I have noticed that last flight of day on West Coast for Southwest always tend to have delays.

Terrible delay today. also, waited 90 minutes for baggage to unload in Seattle earlier in the week.

There was an incredibly surly flight attendant that ruined the experience

After boarding the plane had to wait an hour at the for the copilot to show up before we could depart

The cabin and bathroom experience was poor as the cabin and bathroom were dirty and showed signs of an older plane that had not been updated for Customer’s, comfort and health. There was gum on my seat when I arrived and dirt spots around the fan and light controls. The flight was almost entirely full, so there was no way I could be moved from my seat. Th bathroom had the peeling paint.

Great crew. Comfortable seating. Nice overhead bin space. My app didn't allow me to check in for my flight to BOS. When I called Support, they didn't fix it, but just told me to check in at the airport. Seat back entertainment was great. Could be better if the audio could connect to Bluetooth.

I'm 6' 2" and even in economy plenty of leg room

great! appreciated the last minute upgrade to Comfort+ exit row, as well

My seat was changed without my consent. It wasn’t a major deal but annoying.

The Airline Attendant found us in flight and moved us to seats in the front of economy due to the short time we would have to make our connecting flight. We really appreciated it.

DL486 could not get to the gate due to jet bridge malfunction. We moved gates. The connecting flight of LAX to MCO was not communicated with. Even though we were in the same terminal, DL482 left without about 10 of us, including a mother and her 3 children. I got to the gate at 7:34 am which is past the 7:20 am last call for a 7:35 am departure. Had they waited 5 minutes, all of us would have made it on board.

Delta has joint the nickel and diming airlines. The experience is getting worst by the day. 1,000,000 miles for a trip to Asia in Business Class where I got the same thing for just under 90,000 miles through an Asian airline. Where is Richard Anderson? Please come back!

It's not United, but TSA security at Terminal A in Newark is a disaster and seriously makes me consider switching to flying out of JFK. The touchless TSA pre-check had a line of over 50 people and the bag screening was so slow that it limited the flow of people through the facial recognition process. It is the only airport that I frequent that has this issue and makes me reconsider whether I should fly out of Newark given the wasted time and frustration it causes. As I said, it is not a United issue but will impact United if people choose to stop utilizing Newark airport because of the poor experience.

The food could be much better. Also very unfortunate that most of business class seats were empty but I could not upgrade.

Bag got checked but I thought one personal item was guaranteed.

The seats are very small, that is all the staff did a good job.

The flight was for my mom in wheelchair the staff in Newark wer not friendly took a long time to even get a wheelchair she almost missed her flight because they finally got a chair few minutes before boarding they had to rush her to the gate. They took her carryon and checked it as a bag told her don’t worry free of charge but they charge the credit card anyway. She also told me the seats are not comfortable at all as if they were broken she could feel the bars in the seat SFO staff was much better overall she had the worst experience

First class flight crew was barely available. They came through 3 times while we were on the plane for nearly 4 hours.

The food was horrible. There was no. Wifi, and it was just terrible from bangkok to d. C

My flight got cancelled. Couldn’t get my luggage. It arrived at my destination ahead of me. I didn’t get my preordered meal. Had to spend the night in the airport.

United did nit provide any updated on flight crew not bein available until boarding time started. It was bad. Itws alate night flight and there no proactive communication and iha d an important meeting that i missed due to thus

Delayed too much. 1.5 hrs in the airport and another 1 hr in the runway. Got too late in the night. There was no proper food available.

The boarding process was slow and we had a delay on the tarmac, not the fault of the airline. They had ZERO food options available for purchase which shouldn't happen.

They are always late and seats was also not having working charger

Everything about the flight was lovely. My only suggestion would be to offer a few more options of tv series from Apple TV or HBO.

Did not get the seat I selected and paid for.

Honestly, I haven’t flown American in years, probably due to the pandemic and my being unable to travel for certain periods in the last two years, but it was a good experience to dig out or obtain a new American Airlines account after many years of traveling for business with American in the past.

One bottle of water and a package of cookies for comfort plus. We had to literally beg a flight attendant for an extra bottle of water later in the flight due to feeling dehydrated.

For coast to coast travel the A321 and even the NEO, even in first class will never be excellent. That would take a B787 or 777 to accomplish.

I was unhappy with having the seat I chose changed at the last minute. I was moved to an aisle seat which did not recline and was next to the bathroom. The bathroom odors made the flight entirely unpleasant. Having carefully chosen my seat months before I was not pleased with my AA experience. In addition, they ran out of tea during flight service, really?

There were delays on both ends. It made it less than excellent. This plane was great though

Attendants were rude. Scowling. Seats were miserable and we paid extra.

It got me to my destination? However we were an hour delayed departing, and we never received any updates or notifications from staff. Poor communication and customer service.

My experience with Frontier was terrible. We were delayed for 2 hours. At one point during the wait at the gate I left to go get a sandwich - I was gone probably 15 minutes. In my absence, they decided to move our flight up, boarded and left. When I came back the two attendants were very rude and I unavoidably had to purchase another ticket on the next flight. During this whole time, the Frontier app did not update the departure time, so I was SOL.

Flight was delayed by about an hour, once we arrived at LAX we had to take a shuttle to the baggage claim - it was completely disorganized. The agents at the shuttles were rude and unable to provide any information. Frontier charges extra for everything from bags to drinks - at the end it ends up being more expensive than flying the better airlines

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

I really didn't like anything. Paid for my checked luggage online ($79) and then was told that I would have to paid another $79 for my carry on. Was not allowed to enter the terminal until 3 hours before my flight and when I finally was allowed to check my bag and enter, my flight was delayed 3 times. When I finally landed, we were all instructed to "run off the plane" as they had to do a quick turn around to Las Vegas. Me and several of my flying companions will never fly Frontier again.

Our flight was canceled. I will never use Kayak nor Frontier for travel again. The entire experience was a headache.

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

i was unable to check in the flight. refund requested

I think Frontier was very good at communication. Their app worked very well. Loading was great and the flight was nice and easy.

Great for the price. No wifi or entertainment, but gate agents and crew were fantastic and we boarded quickly and left on time.
