The new seat assignment thing is wierd. If you don’t pay for a seat they always assign you a middle seat regardless of how many people are on the flight. Idk… the new company that bought Southwest is trying to make it more profitable, but I’m just not seeing it. The flight attendants aren’t having as much fun anymore. It just feels like the airline is slowly dying. IMO. We shall see if Southwest is the next Toy’s R Us.

The Air hostess were very rude on my flight from Houston to Austin . Their regular communication itself felt a they are shouting at people.

Plane was late. Zero service for 2+ hour flight and it was not that bumpy.

I have roller bag with food and medication told me I couldn't bring on my 2nd flight today. 15 years flying with SW never an issue with that bag.

Great flight. Good snacks and drinks. Grateful it was free. The flight from Nashville to louisville, i think her name was Tracy (not sure that's right) super awesome, nice and cheerful. She really enjoyed being at work today! She was the person who scanned the boarding pass on flight wn941. She should be recommended for a raise !

I elected to pay for the upgrades and found very little difference

Flight was hours late, unable to sit next to spouse, I have had so much better experiences. Substantially better, only saving grace was that it was a short flight.

The WiFi and crew on the plane were good, however, the boarding experience was awful. I paid for the Choice Preferred and was boarded in group 5 so all overhead storage was full. They found room for our luggage, but further back making getting off the plane a nightmare. Also, we were in row 6 and the seats were extremely uncomfortable. Both my daughter and I had no leg room and couldn’t wait to get off the plane.

The seats are now more narrow. I paid for front row the seats in the front are even more narrow than before.

I was assigned seat 7E, yet my boarding was Group 5, which caused me to have to put my luggage in the back of the plance above `19 or 20 aisle, as passengers who had boarded earlier took the overhead bins in the front. SW needs to monitor bin space and ensure that bin space above the seat are aligned to those sitting near their seats. Also the seating assignments needs to align with group number. Maybe board those last first and so on? Having said the ALL the passengers on the plane were gracious enough to allow me and other passengers in this dilema to retrieve our luggage and helped us along the way. I always love the flight staff, as always their fantastic and I can't rave about them enough!

It was perfect! I've never flown with United before, but I definitely will in the future

I've been flying American mostly, and it's been very frustrating. This united flight makes me realize maybe the issue isn't flying, but the airline. United was a significantly better experience. The plane was more comfortable, with a normal amount of leg room (vs the ridiculous reductions AA has made), more comfortable seats, screens to watch movies. It was a much better experience!

We had excellent customer service despite the chaos at George Bush airport in Houston!

It isvvery small flight. No leg room . No space to put my personal item at feet.

Didn't make the flight because the first leg of my flight was canceled and the next leg was already booked.

Terrible because it was cancelled due to volcanic ash clouds in Guatemala while all other airlines kept flying. Had to pay for a hotel to stay overnight in Houston and try to fly next day.

Overall we had a good experience during our flight from San Francisco to Houston.

Airport terminal was outdated, flight was on a small jet with no wifi

The crew made our experience extremely bad. They were rude and didn’t have anything for kids.

The power at the seat didn't work and the seat itself was difficult to adjust - this was a business class seat. Flight attendant gave me miles to compensate. The attendant was very professional and on top of his game the entire flight.

Seat was VERY uncomfortable. Flight was delayed and then boarded slowly. The crew was super helpful with boarding and supporting maximizing the luggage in the overhead.

The flight changed gates multiple times and flight had to be delayed multiple times

Delayed for mechanical and no updates on what was happening and how long the delay might be.

On the return flight, arriving in Denver we sat on the tarmac in Denver for over 20 minutes.

Absolutely terrible. Would never fly American again. 2 deplaned incidents and delayed by close to 24 hours. $12 meal voucher for first class passengers was an insult to the injury. Pathetic.

Mostly good. The WiFi wasn’t working so that was not great.

I rated the experience "mediocre" because of the 2 hour delay in take off. This is the 4th flight from DFW on AA where there was a delay and in one of the instances (after 13 delays), the flight was cancelled. I understand weather but for the March 18th flight, there was no weather issue in Dallas or Detroit. I called Concierge Key and they were wonderful, booking me on a later flight in case my flight was cancelled. I have flown with American for many years and never has there been this consistent pattern of delays. Very disappointing.

As a first class customer, there was no power the entire flight which limited my ability to work. I find this unacceptable. The first 11 rows on the left side of the plan were out. I was only offered the option to charge my phone which was not the issue because my laptop was out of power. I asked if there was anything that can be done for me, and the answer was, "no". I was not offered any type of compensation for this AA problem which caused me unnecessary stress due to inability to address business issues on an already challenging travel day. Flight attendants tried to reset the power once but that was the extent of their support. Very disappointing for the lack of expected services on a flight. Please contact me with customer focused response to this complaint.

Easy boarding. Rows are smaller but that may be an older and bigger me now :)

Check in was rough because the check in crew did not know how to manage my international visa documents. Required a long process and 4 people to finally be able to proceed to security. They told us incorrect information several times before acknowledging we did indeed have everything we needed from the start.

Horrible airline .. my flight was cancel , the only offer to flight next day was no good for me , representative from spirit advise everybody to buy the new ticket from southwest airline and spirit will pay back the money we spend on new ticket but after we did this they don’t want to pay us back , .. customer service is not help anybody Chat text messages it is horrible also , robots can’t answer and help u with anything … I send the complains to head quarter in Miami and department of transportation

I cannot effectively rate the food and drink as I had not. Otherwise, the trip was fine. The seats were nice, the crew was fine. They could smile once in a while. They all look like they were mad.

Flight was delayed due to waiting for crew! Flight attendants did not offer us food or drinks. Did not communicate with them at all other than at boarding and leaving the plane.

This was a horrible experience for both KAYAK and Spirit. My flight was canceled with no alternative flight option. I paid $600 for a last minute flight and didn't receive an email from KAYAK regarding the cancelled flight until hours after it was canceled. Never again for either.

I purchased extra legroom so I will be comfortable but the guy behind me is a big guy who keeps on moving and since he is big I can feel his movement at the back of my chair.

For the price of the fare, there really isn’t much to complain about.

I arrived two hours early, and at 9:20 I was still queuing for security.

The seats are the most uncomfortable seats I’ve ever sat in. Don’t believe I’ll ever fly spirit again!!

No leg room. My knee was sore for a day.

Flight was delayed. (To be excepted because of TSA shortage) I’m super short and still struggled with leg room, there was no screen, and the seat didn’t recline at all.

They switched our terminal 3 times and we were delayed for four plus hours!!!

It was an early flight and most people napped/slept and the crew let us which was nice.

The crew acted like they had never done this and kept barking passive aggressive orders at people. + the security line + the delay + sitting on the tarmac for 2 hours + none of the apps or signage updating with correct times

More inflight connection. And leg space is horrible. And the paying for baggage I'd ridiculous!!!

My flight was originally from SAT to MCO connecting from MCO to ORD. We got diverted to ATL and than Frontier staff there was sooo un helpful first they said they couldn’t give us any accommodation since our flight first got delayed that cancelled and now it’s 221am and I am still in ATL since they said they need to create a new flight my final destination is ORD and I have been delayed twice and cancelled. With no real help the frontier app didn’t work no email updates over all such a horrible experience

There's no seats that lean back with little leg space i wad uncomfortable the entire flight. Your charges for extra baggage is despicable and costly!!

Remind customers of the need to have passport or new ID for boarding.

Flight was canceled. Most upsetting was message from Kayak, stating that the flight was canceled and click with Kayak for details regarding rebook, refund details. THERE'S NO INFORMATION PROVIDED BY KAYAK EXCEPT THAT FLIGHT IS CANCELED. AND NOW THIS SURVEY TO FIND OUT HOW WAS THE FLIGHT !!!!!!!

The flight never took off and we spent 7 hours at the airport

Gate not determined until I got to the airport - hard to plan the trip to the airport.
