The last 30 min or so, they put the heat on full. We thought we were being basted.

The last 30 min or so, they put the heat on full. We thought we were being basted.

I like that it was on time and the staff was friendly.

No space for our carryon and needed to check at plane before boarding !

Flight was ok. Boarding wasn’t fun. Flights were delayed by 12 minutes on each leg.

The plane wasn’t full, so we got the best seats

The flight was semi-full with enough space to spread out. Wonderful, smooth, and quick flight.

We boarded the flight and set two and a half hours on the jetway. Would have been better if they had not boarded us at all. Plane was hot and it was limited ability to access the restrooms or get a drink of water. Very unpleasant experience

The flight was great. We were not offered any beverages though. And there was no real turbulence, so not sure why.

I liked the boarding process with our loading group and numbers. I disliked that I couldn't guarantee our seats together. I didn't like that the Internet costs $8/ flight, but did love all the inflight options available through their app. I disliked no charging station at my seat for a 3+ hour flight.

I think Southwest can offer a whole can of beverage instead of such a small cup

I sat in comfort plus. It was fine. Seats were comfortable. I got drinks and snacks.

Crew was nice. Flight was timely. Seats could be better as well as the food considering it’s first class.

Left on time and arrived early this extending our 31 minute transfer. Bags made it also!

Good and consistent Printer in lounge did not work for me :(

Most of my discomfort was going through TSA. However, the Delta seats had inadequate leg room and I tried my very best to connect to the wi-fi and it was a cumbersome process that finally gave me the info that I needed to sign in AFTER I had completed the flight...Why make it so difficult to use? That said I really really appreciate the pilot taking a little extra time to avoid a bad storm area and both landings in Atlanta and Orlando were flawless to my delight!!!

Delayed in taking off because no flight crew. The in seat entertainment was working properly.

I upgraded to first class only to find out that I still had no access to the sky lounge without a sky miles card or AmEx (something that should be emphasized outside of the fine print!) Also, no food or drink service provided during the flight, so I basically paid 4x more just for “free” checked baggage and a bigger seat. Not worth it.

Delta was really good about being transparent with why we were delayed it’s just that’s the plane was really old and outdated and a lot of the comfort and amenities we know Delta to have did not shine through

Bottom seat cushion is almost non existent. Very uncomfortable seat.

Delta was great the entertainment was outdated. Screen was very small and didn’t work.

They canceled our flight and left us stranded to figure it out

Everything was very good. Was able to change a make run flight leaving on direct earlier in the app -seamless!!! Well done

Being stick waiting for gate at ORD cause me to almost miss my connecting flight…being deaf United made no no effort to keep me updated as I couldn’t hear the PA

As usual, United scheduling is completely misleading. A 54-minute layover at O’Hare is too short to make a lot of connections, especially since the flight landed “on time” but had to wait on the taxiway 15 minutes for a gate to open up. Then it takes another 10 minutes to exit the plane before one can run to another concourse to catch a connecting flight.

The seats on the aircraft are like sitting in a rock. During the boarding process they recognize Active Duty Military, why don’t they recognize Retired Military. I’ve always preferred Delta, this flight confirmed why I still prefer Delta.

when you can say you don't remember being at any point upset during a flight, the airline is winning .

The staff was very friendly. The seats seemed quite small. Overall the flight was pleasant.

It was literally one of the worst travel experiences ever. My flight got delayed by over an hour and there was no communication of this from the gate staff. I realized it by checking the screen periodically. Once on board the flight attendants continued to serve alcohol to a man who was clearly already drunk and that was making a bunch of commotion. Never again will I fly United!

Charging and entertainment didn't work. The meal was horrible. They only came by with the drink cart one time for the 8 hour flight. They did come by with water a couple times.

Exceptional, I’d like to specifically recognize Robert for his outstanding customer service. He is professional, pleasant, and personable.

It was nice being on a flight that had working wifi. The boarding was quick - why don’t all airlines have small boarding groups window to aisle? Makes so much sense!!! I was disappointed to be the first person stopped to have to gate check my carryon. Especially when there was plenty of overhead space at the back! But I get it…keeps it moving. Crew was nice.

The flight from Buffalo to Chicago was on an older and smaller plane. Seating was tight. Looking closely at the interior of the aircraft there were definitely signs of aging and wear.

Domestic airlines have really fallen from what they used to be.

The flight encountered a delay exceeding 4 hours. The food voucher issued was valued at $12, insufficient to cover our meal expenses. Consequently, I was unable to take my medication, leading to a drop in blood sugar levels and exacerbating my anxiety.

Overall good. Tight connection in DFW because of gate unavailability upon landing.

Airplane was cold. Flight attendants were rude. Phone charger did not work. No food available.

3hour delay In the last 3 months i had 3 flights and 2 of these had a more than 2:40 hrs delayed

My initial flight to ORD was extended without reason. We circled the airport a few time and then drove on the ground for at least 20 minutes. These kinds of delays are annoying but somewhat expected… it would be nice if the crew would make an announcement to give updates on how long we could expect to be delayed.

The flight was uneventful. What was a problem was I was delayed getting home one entire day because the flight from Sacramento was delayed. That made getting to my connecting flight impossible. I had to stay another night at the hotel and incur that expense as a result.

Flight was on time, no drinks served on the two short flights. Comfortable seats.

The flight landed with a delay and we had to wait almost an hour to be off boarded. So typical of spirit.

The gate employees and the flight crew were friendly and professional. Afterboarding we waited 20 minutes for another flight; a complimentary beverage would have ben appreciated for the inconvenience.

You get what you pay for, but those tickets weren't cheap, so I expected better, but Spirit is just one of those airlines.

Cancelled the return flight moments before boarding, horrible customer service in assisting with any rebooking. Never again will I fly Spirit.

It was on time, no issues, everyone was courteous and of course, affordable.

Flight got diwngraded last minute and left us stranded. I was told I’ll be given credit for my luggage and seat upgrades but haven’t got anything yet

Crew was nice, explained emergency protocol very well. Flight took off and arrived on time. Pilot explained the small delay that occurred with docking and providing updates. I would definitely fly spirit again.

The seat are terrible. Don’t even think of sleeping on a Spirit flight. The kids that run the plane aka flight attendants are pretty rude and straight forward. They get the job done but without class.

I had a death in my family and booked my flight on Spirit. My flight was cancelled the morning of my flight, no explanation, no help to rebook, nobody to talk to. The next available flight was 2days later !!!! Terrible airline, will NEVER fly with them again!

They took a horrible route with a lot of turbulence and I eneded up getting sick. Even if the flight takes longer. Don't put people life at risk just to get to the airport on time.
