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 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!

Great vacation. Can't wait till next year for another one.

We got exit row seats both flights. Everything was running on time

The flight crew was extremely rude and especially not helpful when our flight was delayed.

Flight was fine other than there was a gate change that I was not notified of. By chance I happened to check my phone and saw the change, otherwise, we would have missed our connecting flight.

Check-in, Boarding and flight were smooth. All the employees and crew was very nice and funny. They gave the kids crayons and workbooks to keep them occupied which was a big win. I’ve flown Southwest many times and that’s the first time I’ve seen that and it is a great addition.

Still a fan of open seating. Flight was on schedule and arrived on time. The 737 MAX is very comfortable.

Had to get off plane from prior flight even though I had to reboard same plane to continue to my final destination.

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.

I like flying first class, and United has a nice one

They lost my luggage, so, not happy. The crew was nice but my suitcases never made it, still trying to find out what happened!

Unbelievably poor service from flight attendants. They didn’t even do water service on a four hour flight. Just disrespectful.

Flight was delayed 8 times. We were sitting at the airport for 14 hours. We got 2 hours of sleep (if that) on what was not meant to be a red-eye.

Seats had less pitch than a regional jet. Food was OK. Have to buy alcohol on US based carriers flying international. Boarding was a mess. Did not have bags but overhead space was gone quick. Would like to see the airlines enforce the one bag over and one bag under policy

Lately I like the planes have been exceptionally filthy. There’s lines of dust and dirt all across the ceiling in the vents, and the cracks in between the seats are literally full of food. It’s definitely not the quality of service that I was used to with United. I’m also very disappointed with the Wi-Fi! All I wanna do is knock out a few work jobs while I’m trapped in my seat And it spools so bad. They did provide me with a refund, but the process of getting that refund is so complicated. It’s unfortunate.

The TSA check in took 1.5 hours to get through in Austin and I missed my flights back to DC

There was free WiFi (definitely a plus), but the flight was delayed 45 minutes waiting on a catering truck that never arrived. The pilot said there would be food vouchers given out at the end of the gangway to make up for the inconvenience, but there was no one offering those. Delay made me late for work!

Flight was on time and there was an empty seat next to me. That makes for a good flight!

We lost a day of our vacation because AA did not get the plane to the gate on time. Even though the gate attendant was very clear that it was not weather related, AA would do nothing because there was some snow that day. They basically said the gate attendant was wrong even though she was on the front line of the situation and they were not.

The seats are too uncomfortable for anyone over 5ft 8in. I'm 5'10" with a back and hip issue and I was in pai for the full duration of the flight.

Flight was on time and the meal and service were good.

the plane was so hot!! the air-conditioning was barely blowing. The flight was delayed, and we had to sit on the hot plane before take off for an extended amount of time, waiting on international passengers. Would not have been so bad if it was not so hot. They said it would get better after take off, but it did not.

did not have enough meal for first class passengers so offer us snack

Old equipment, needs upgrade and seat comfort. Internet didn't work 75% or the time.

Update to handle the delay was very bad, crews no smiles or welcome or thanks. Don’t care attitude

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.

The Hawaiian lady that boarded me was rude and the one help me a the ticket counter was rude

Vegas is such a quick flight that amenities aren’t the important part, in my opinion. Just get me there efficiently and safely, and that’s exactly what they did!

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

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

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!

This is my second time flying with Frontier. My current experience was very favorable. The staff from the gate to the plane was friendly, warm and professional. The food options lacked in my opinion. This area needs some attention in my opinion.

There was no food and no entertainment, so I'm not sure why these are even in the survey, as my understanding is frontier does not ever offer food without a few, not even a snack, and there are no screens so unless the flight safety talk is our entertainment why ask how we liked it?. One of the flight attendants say in the back of the plane as people filed in to their seats, yelling orders about where to put baggage and telling people to hurry up. It was the least professional experience I've ever had on a flight.

Very well recently! Frontier is improving and less harrassing customer on luggages! Positive!

Good for a budget airline! It was easy to get on, staff was really nice. Can’t say anything about the food or entertainment because it wasn’t available, which is fine.

I am writing to express my disappointment with my recent Frontier Airlines flight. I was charged $99 at the gate because my bag was said to be too large, yet once onboard there was no available overhead bin space, and I was required to place the bag under the seat in front of me anyway. This made the charge feel unnecessary and unfair. Additionally, before the flight even took off, I was asked to move from the seat I paid for into a middle seat so another passenger and her cat could have my seat to themselves. I was not offered compensation or an explanation for being moved from a paid seat. Between the unexpected bag fee and being forced to give up my seat, this experience fell well below acceptable customer service standards. I would appreciate a review of this situation and appropriate compensation.

It was costly and difficult to check in. $85 to take a small suitcase with me, carry on or checked and $75 on the return trip, Plus $25 if I didn't check my self in check in $25, because I couldn't do it on the kiosk. Small very uncomfortable seats, waited on the runway for near an hour each way. It was my worst flight to date.

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