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.

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.

Service was great, boarding and exiting went smoothly, and the flight was very pleasant.

Southwest is amazing. The only issues I would have to say is. I don't like the unassigned seating, and the fact that the flight is completely sold out. It makes for a very tight fit. Other than that. Crew was great fun professional and attentive.

Everything worked well. Crew was as entertaining as is possible on a plane flight. Southwest still has good legroom:

Great overall. There was a bit of turbulence so they could only serve water because too much turbulence for the carts. Was glad they prioritized safety though

Excellent flight, the planes were newer, they did a nice job with boarding, great service overall.

Great service. Flight was delayed while we sat on the runway for a couple of hours. Weather related. Staff made is very bearable. The steward servicing the first class cabin was exceptional. Thank you! 💗

5 hours of delay that could've been much shorter if Delta had taken the 1 hour delay they imposed on the flight before boarding to run any of the plane checks required for flight to find the hydraulic issue that required nearly 3 hours to fix. $24 of meal credit buys a sandwich and a soft drink. Poor communication within the terminal about what gate we'd be re-boarding from and when we'd be re-boarding.

Amazing flight! I have never noticed the uniforms of the attendants before in twenty years of flying except today when one female had the most amazing dress on. It was beautifully designed and showed she was in charge. I never dreamed I would google who designed Delta uniforms . The ultimate compliment is when another woman admires your outfit. . I hope your designer puts it on the market

It would be nice if was given wires ear buds. Overall was a good experience was able to sleep on the plane

My flight was 6 pm 6/6. Every hour they delayed it again - air condition issues then no pilot then the crew had worked too many hours and cancelled the flight at 11 pm. Sent customers to NJ a 45 minutes uber ride to a hotel. Had to be back by 5 am for a 7 am flight and again no pilot etc with another three hours of delays.

The entertainment and wifi mostly didn't work on this flight.

Terrible entertainment system - kept freezing and audio kept cutting out. Snacks were mediocre at best for a 5 hour flight.

The check in and bag drop off for Sky Priority members is slow. The Clear security was also slow - a TSA issue.

I always appreciate when everything is on time! In this flight you have a short connection and it could be stressful , but is was easy and fast. They even ask people to wait so the ones that have a short connection could leave before. It was the fist time that something like this happened.

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.

My suitcase was destroyed. The top part where the handle is is completed broken. And unusable now.

Since when do I have to pay for my checked bag? I have a United Explorer mileage plus silver card and I was charged for my checked bags. This also is an international flight. So I would like an explanation to be clear before I choose an airline please?

Michael, our FA was very attentive, even finding me a chocolate brownie from economy class when the dessert selections were all dairy based. ( intolerant, not allergic so don’t usually need to order dairy free)

I had a bad experience with the security at IAH and felt like a sardine on all 4 legs of my journey.

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.

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.

Update.us on flight information in a more timely manner. Don’t say we are boarding on time ten minutes before the boarding time when the aircraft isn’t arriving for another forty minutes.

Several delays. Next flight was worse. Did not arrive home until 2am PT

Easy boarding and good flight. Need to work on the beverage and snack situation

The staff was great, but because the 2nd lieutenant didn’t show up for the flight we all had to deboard and wait 2 1/2 hours for one to show up. Very disappointing the crew can’t get schedules confirmed which wouldn’t have caused this issue.

Flight and crew were good, no complaints at all. Easy, uneventful, quick flight. The delays, cancelled flight, hold time to wait for customer service on the phone were not good. One person that answered told me the delays, first on the way to Newark, and again on way from Newark were due to weather (there was no weather on flight coming in); turns out that was not true. Multiple flights were delayed and cancelled that weekend- 6 for the trip leaving on Sunday from what customer service at the desk told me. Newark was having issues with air traffic controller I believe. So, getting false information and only options of rebook (for another day, or one with stops to get in the next day), refund or a credit valid for 5 years, did nothing to help me get to work the next day or get my son home for school that next day. There was no sort of compensation for the wait or cancellation from airline or from airport. Just out of pocket for the uber ride and the missed hours at work.

Flight was delayed a bit, but that was expected (and updated), so really not bad at all for the price. Could’ve used one less email asking me to upgrade my seat; otherwise no significant complaints

Easy boarding. Met expectations for a 2-3 hour flight. Early arrival at DFW caused a 39 minute delay on the tarmac in getting to our gate. 😏 overall, good flight.

My experience with Spirit went pretty much as expected. It's a no frills airline, and you get what you pay for. I don't require much, so I was grateful to have an inexpensive way to travel. It is sad to me that the gate agents and flight crew don't smile much or seem very friendly or helpful. They are competent and efficient, and that's really all I need.

It was fast but uncomfortable seats. Had to pay a bit extra not sure why? Maybe in selection of all my 4 tix together ? Just knew I had a balance before getting boarding pass online when departing from satx ? And flight was delayed..

Last minute 2-3 hr delay in flight schedule; no explanation Unexpected extra $52 charge What's the benefit of choosing a cheap airline if you trick people last minute and force them to pay extra last minute? Did not appreciate being cornered.

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.

Seats are uncomfortable and too close together. Also, you missed my connection in Vegas on the way back and I ended up sleeping in the airport, flying back to Burbank instead of LAX and I got home 12 hours late.
