The checking experience in Orlando was terrible, almost missed the flight. Too many travelers and Southwest completely understaffed.

I'm glad it wasn't only 75% full because I could get a good seat
if I was good. Not happy that I have to pay extra money to get the seat I need for lake room, but I guess that’s a sign of the times.
Seats were very comfortable. They tilted back. Drinks and snacks were free and served 3 times. Attendants were awesome.
Plane was clean and comfortable. Flight attendants and gate staff were professional, friendly and efficient. Boarding and deplaning were orderly and efficient. All in all, the typical excellent Southwest experience.
Truly terrible. Will never willingly fly southwest again. Seats are worse than before they switched to assigned seating. One flight attendant was the opposite of helpful (rude, unhelpful, dismissive, and as my stranger seatmate said unprompted: a total prick). This caused me, 15 minutes into the flight, to book an alternate return flight home on a competing airline (first class 1.2k purchase instead of my existing planned flight) just so I would not have to ever be on that aircraft, with that terrible service person, with those horrific seats ever again.
Not having a five hour delay with little notice! The crew was very kind, though, and just as tired as we passengers were. The flight didn't depart until nearly 1 am...and no reason was ever given.
The entire experience from boarding to landing was amazing! The crew were very friendly. Will definitely be back.
no service at all due to turbulence. they should've at least given us snacks, there were only 10 people on the entire flight.
First time I've had to use the disabled accommodations. And I could not have had a better experience with Southwest, i was having trouble getting from one terminal to another due to my heart failure. And the next thing I know a Southwest agent had made sure. I had a wheelchair at all my flights. Can't thank them enough.
Seats were very uncomfortable and being charged for snacks and water.........
Allegiant actually impressed me, original inbound flight from PBG was so late they gave us a bird inbound from Des Moines and only left 1h late and gained 40 minutes back in the air. Comfortable flight with no frills but no complaints.
Flight was delayed. Crew was good but hot coffee was not available.
Great. No choice for n/a. No food or entertainment options
No food is available without purchasing it and there is no in-flight entertainment. Both of these are OK because we got an inexpensive flight from Allegiant and, otherwise, our experience was excellent.
just had water and there was plenty of leg & seat room. But then i don't weight 220#s!!
Not totally their fault- screaming kids that had zero parent intervention.
It was cold on the flight. The crew was very pleasant. I didn't order any food. We were delayed due to Captain waiting on maintenance log. He kept us informed though. The flight itself was smooth. I would definitely fly with Allegiant again!
I had a fantastic experience with Allegiant. I had wheelchair assistance and they helped me find my luggage and brought me to my car. Even loaded my luggage. Wonderful service!! Thank you Allegiant!
Superb. Staff great. Great flight. As with other airlines, seating too tight and restrictive.
Fine. Nothing to write home about. The plane left on time, and arrived on time.
I was downgraded from first class to coach due to an airplane change. They pulled me out of line and I was the very last person to board the plane stuck in the middle seat with no overhead place to put my carry-.on. Very poor customer service.
Seat comfort was poor (no lumbar or lower back support).
The airplane seats were spacious and comfortable, and the flight attendants were friendly and attentive. The food was delicious like never before. The blankets and toiletries were thoughtfully provided. The captain's navigation was steady and reliable. In short, having flown with Starlux, I won't consider any other airline next time.
STOP MAKING THE SEATING SO CRAMPED. WE NEED A PASSENGER BILL OF RIGHTS!
The passenger in front of of me reclined their seat back all the way the entire flight. Their headrest was in my face the entire flight! I barely had room for the little plastic cup of water to fit on my tray table; can you make the seats and space between the rows any smaller??? You can’t even get up to use the restroom! Worst flight I’ve had in a very long time!
We had several flights and they were all on-time and flawless
My Frequent Flyer nber wasn't put on as I was told it was..... This resulted in a last group boarding and no priority tags on My bags.
Terrible steward... Plane was quite empty... I asked to move "back" in the plane and the steward said no... Unnecessary power trip of mediocre people.
The small flights with Valet Luggage has a poor service
My flight was delayed then put back on time then cancelled and they automatically rebooked me to another flight but that flight was going to make me late to a concert i had planned for. Flight was at 10am concert was at 7pm from Burbank to Las Vegas so I allowed enough time but the flight that was rebooked was too late so I talked with the desk and they were able to get me on an afternoon flight. Thank goodness. That was stressful for a moment. I want to thank the person who helped me get to my show on time. Concert tickets are very expensive and the show was amazing. Hopefully my flight home will be smooth.
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.
The staff at the check in counter was so rude. Made you feel Incompetent
Frontier scheduled a 40 minute connection in DEN. What they failed to mention was that they “close the doors” 20 mins prior to departure, which means you only have 20 mins. Not enough time. Possibly against DOT regulations. Filing complaint.
Flight was scheduled at 9:40pm. Got delayed to 10 am, the next day. crazy
The bag check, flight check-in, and onboard experience convinced my wife and me that we will actively go out of our way to avoid flying Frontier Airlines in the future. At bag check, we were informed that check-in could only be completed via the Frontier mobile app. Unfortunately, the app was extremely frustrating—sending us through repetitive, confusing loops that repeatedly forced us to decline add-on services with nearly every click. While most airline apps upsell, this one felt intentionally exhausting. As the process dragged on, we became genuinely concerned that my phone battery would die before check-in could be completed. We approached the bag check staff—who were standing together talking—and explained both our frustration and our predicament. They laughed. Later, my wife described the interaction as “gaslighting,” which felt accurate. We were then informed it would cost $25 per person simply to have our boarding passes printed. From that point forward, the tone of the experience was consistently hostile. The bag check employees were condescending and combative, behaving more like bullies than customer service staff. Unfortunately, that same attitude continued onboard. One flight attendant argued with me when I attempted to stow my backpack in the overhead bin. I explained that we had each paid $75 to check our bags specifically so we would not need to use carry-on space and could have adequate legroom. She demanded to see my ticket, pointed out that it said “no carry-on”—which I acknowledged—and I reiterated that this was precisely why we paid to check our bags. Her response was, “I don’t make the rules.” She then walked away, but not before asking if I “truly wanted to fly back to Chicago today?”—an unnecessary and unmistakable threat. It is also worth noting that despite booking our tickets together in the same transaction, we were not seated together. Upon our return to Chicago—where we could once again sit together—we compared onboard experiences. We both remarked on how unhappy the flight attendants appeared and how each of us was separately asked whether we would like to purchase a beverage. We declined. At no point was water mentioned as an option, leaving us with the clear impression that even water came at a cost—or that complimentary water, if available at all, was deliberately left unmentioned. Overall, the experience was shocking and deeply disappointing, but it was also a profound learning experience—one we will not forget and will not repeat. -Steve
Plane was hot and miserable and the crew was rude!
12 hour delay required getting on and off plane 3 times - would have at least liked to have been offered a snack or drink
They didn’t offer a water, even after I asked
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
