Southwest is typically delayed, and it gets wearisome. It is no longer a discount airline and you get way less than you pay for when it comes to comfort and Ce.

Southwest is typically delayed, and it gets wearisome. It is no longer a discount airline and you get way less than you pay for when it comes to comfort and Ce.

Staff was far less than helpful at all times. Departure and arrival times mean nothing to Southwest. Extremely disappointed, will never fly with them again, and I’ll be sure to share my experience with all.

The seats were a bit cramped and worn, but otherwise okay.

Short flight with plenty of open seats. Drinks and snacks were still provided even on such a short flight. <1 hr

Multiple delays and gate changes. Arrived at final destination 6 hours late. All rental cars had been taken.

The movies using Southwest WiFi kept pausing and I had to restart multiple times.

First, my flight was a usual flight nothing exceptional or unexpected. Over all it was a normal, good flight! Second, your questionaire is wholly lacking in the proper options to which one can answer a question. Often on short flights, there is no food let alone entertainment so why isn't that reflected in your questionaire? A simple "not applicable" would cover that issue appropriately but no, your form arbitrarily enters an answer based on the initial assessment which normally isn't factual. Until you provide an accurate means of assessing flights, I'll no longer be completing of these unimpressive and misleading assessements. Thank you!

Easy to book and to get check in and get on and off.

First time I’ve ever missed a flight and it was an international flight.. Southwest put me on the next flight and it was the best experience possible.

It seems as though the provisions are even less. Although SWA used to be an economy Airline, that isn't really the case anymore. I paid over $700. for a round trip to Denver and I could have flown just about any airline for the price. The drinks are now in a 6-ounce cup and with ice I'm sure a can would fill more than 2 cups. However, I am very proud of SWA for using paper rather than continuing to contribute to the millions of plastic cups being used each day. I've thought of this fr many years and am so glad to see it come to fruition, if not by only SWA so far.

Gate agent did not hold flight for connection, provided no assistance to get new flight

The plane pushed back from the gate on time. However, it stopped on the ramp, and we waited for over 20 minutes before the aircraft pulled back to the gate. Apparently, something of importance had to be removed from the aircraft by the gate agent. I found this to be odd. The delay was not significant, but I felt that whatever was on the aircraft that had to be taken off, should’ve been done before we pushed back from the gate.

Smooth boarding process. Early departure, smooth flight, early arrival. The entertainment package has very good recent movie options. The flight crew were friendly and professional.

I don’t understand the purpose of the orange “priority” tag on my bag. This tagged, my bag is last or near to the last bag to come down the carousel at IAH.

Oh my gosh, I loved my experience with United! they made me want to travel more often.

The planes are so dirty! Food crumbs and finger print smudges, Dust over the vents and carpet stains. It’s disgusting.

The bag drop personal were not helpful. There was no food on the flight. Boeing aircraft, lousy as always. Everything else was fine.

Asked several times dairy free options and was ignored. Was told chips was the only thing I could have that I should have put it on my profile “which it is”. Very unprofessional. WiFi didn’t work have the flight. Overall a very bad experience.

Plane still had screens for watching movies. Good selection too.

Flight crew was amazing! I don't like that the Polaris seats are side-by-side.

The chair cushions may need an upgrade. I have been noticing they are so worn out, thin so you’d sit in a dip 😄. Other than that, all was an enjoyable trip. Thanks AA!

I’m impressed that we were on time in Sacramento after having a late departure in Newark and our made it. The staff was friendly and warm.

5.5 hour delay with no explanation on why, along with no proactive effort to reaccomodate me.

Plane, flight, crew, captain were all great. The first flight had a Chipotle box lunch...delicious.

Plane, flight, crew, captain were all great. The first flight had a Chipotle box lunch...delicious. this return flight not as tasty, but filling.

So awful Unreliable Unfriendly Bad Mad Mean Smelly Hot Late Overbooked Understaffed Expensive Cramped Narcs If they were a fruit they’d be rotten durian

It’s a great flight. Service is good. Staff is awesome.

Boarding on time and fight was early but they didn't let us off the plane on time so we missed our connecting flight to Japan.

DFW-LHR Toilets not kept clean Too cramped. Aisles so narrow crew were constantly banging into people on the aisle seats. Even then, the carts used are reduced width. Other than that it was a decent flight on both legs

Eventless. It was a good flight and good crew. Can’t complaint.

The flight, the pilot, the flight crew, and the ground personnel were all great, despite the sudden and lengthy FAA Ground Stop in Boston, which SPIRIT obviously had nothing to do with and no control over.

Most uncomfortable seating I have ever experienced. And they do not provide any beverage unless purchased. Water was 4.59 a bottle. Same for a soda. A cup of water should be free. I will never fly Spirit again.

Boarding was not clear; no announcement about delay. My sister and kid were seated separately for me and even though there were tons of seats up front, they wouldn't let us switch.

Bare bones but a complimentary class of water doesn't seem like too much to ask.

The plane had to wait an hour before docking, then another 1.5 hrs to get our luggage. Bad experience.

we are al people and we go through stuff so my scale is only how i felt, I understand we are all humans, i would definitely ride with soirit again, people in orlando are very helpful which makes it all the better .

Your employees need to learn how to talk to people as creations of Yah. We are not their children nor are we lower than them.

Flight was ok with exception of the multiple delays. As with all Spirit flights, the sights are extremely uncomfortable and lack leg space. However, the price savings is the plus.

Okay for the most part but Good boarding and on time

Seats had more cushion in this flight. Otherwise, I got what I paid for. Will avoid spirit airlines at all cost.

Since you have to pay for overhead bags then they shouldn't be running out of space and asking individuals who paid to remove stuff from the overhead

Cancelled flight after I arrived at airport after 75 min drive and parking. Next flight was 4 days in the future. Had to scramble and buy a much more expensive flight on another carrier.

Book with frontier airlines with the mentality that they'll cancel your flight, kick you off and lose your luggage. Anything besides that is a win. Compare prices with other airlines (to include luggage) and if frontier is still worth it, book it but know all of their policies.

You get what you pay for nothing essentially but a hard uncomfortable seat that doesn’t recline and kids screaming all around you and chaotic boarding and limited check bag weight allowance when compared to other airlines

I never got to experience the flight because they delayed my first flight and I missed this one. Then Frontier didn't want to help me rebook a flight to get me to my final destination.

The Boarding process in Denver was chaotic, and since the line was so long, we were lined up very far from the gate. If there were any announcements from the gate staff, we didn't hear them. The flight attendants were spectacular. The only negative part of the flight was sitting by a 2 1/2 year old who was unruly and unfortunately had parents that matched his behaviors. Also, the restaurants in Denver on the E concourse, they didn't have food (passengers could only order 1 item on the entire menu) or the restaurants had 12-14 people waiting for orders to be prepared and another 6 people waiting to order. If you have a layover in Denver and need to grab food, be prepared to visit the shops with pre-packaged sandwiches, or you can visit another concourse but it may take a while to transit throughout the airport.

I liked the turn-style feature at gate 209B at LAX. Very efficient process. The gate staff also made several, clearly directed announcements so I felt very informed.

Although an hour and a half early was told by staff at check in they had overbooked and could not check us in for the flight.

The crew was delayed because they came on another flight that was delayed due to weather 10pm flight left at 1.30 am The airline made no effort to align alternate crew

Plane was down graded and I lost my uncharged exit row with more leg room. No mention or offer of refund from podium. Flight attendant was nice to explain this happens often and that I could request a refund via online form submission. I did this and have heard nothing back.
