On my way home I had a layover. The flight from ATL to CLT was amended 5x while I was waiting. I could have driven home sooner. Overall from Dallas, Tx to Charlotte, NC I started my trip at 4:30pm, I didn’t get home until past midnight. I know things happen, but 5x to make me run back and forth in an airport from different terminals is excessive. I also upgraded to comfort + , I didn’t feel it was worth it. There was no benefit

They did a fine job. Can't wait to use Delta in the future.

There was a loud squeaky sound the whole time we were flying.

Had a broken tray in business class. Crew just shrugged it off.

Seat back monitors and outlets were dead and not working.

Everything was great except for the seat. The backrest would not stay in the upright position.

I usually have a positive experience with Delta. Complimentary upgrades are always nice!

Flight delayed about 2 hrs so it made it a VERY late night

It was a crowded flight. They did the best they could.

Due to one crew member not showing up to work, our flight was significantly delayed causing us to miss our connecting flight in Houston to Mississippi causing us to be delayed by more than 6 hours and missing our event all together. Very disappointing. All because ONE crew member called in sick. United did grant us a $15 meal voucher, which was a small but appreciated concession that I wasn’t able to use because I ordered my lunch and paid for it before applying the concession, and the staff said it was too late to use it. Ugh! We also had a TWO delay coming back from Mississippi, but that was on American Airlines and it was due to weather, so not their fault. Anyway, not at all impressed with United’s handling of our flight and the HUGE disappointment of missing our important family event for our 90 year old mother. All that money and all that stress and emotions for nothing. Having to wait the hour to bring an employee from LAX seemed like something that should not have happened. Why don’t you have a local back-up? Santa Ana is not a little airport in a rural area.

The customer service was excellent! Check-in, baggage check-in, boarding, the flight went very smooth.

It was delayed several hours which delayed our connection in Denver. Not happy.

Ok, but comfort was lacking as the seats were way to small

All good except paid for wifi that did not work

Some of these FA’s need attitude check. Snarky bitches

The plane boarded and deplaned twice before the crew timed out. Flight was 7 hours late departing. Horrible experience!

Got automatically assigned middle seats unless you fork out extra money for a seat assignment, not impressed.

Flight was canceled 12 hours before take-off due to “weather”

The flight was short and that was the best part. The flight was about 90 minutes delayed.

Flight boarded without pilots. Sat on plane for 3 hrs. after over an hour late boarding. Plane never took off. Had to deplane near midnight. Line for rebooking was 3 hours + long. I had to leave.

Missed the flight because of them and up geting a rental car

Delayd flight out of atl as always miss my conection in dfw no flight untill next day

No problems with flight. Even though I had a short layover in DFW, I was still able to easily make my connection.

Good flights. Departure and arrivals were on time. DFW was a little problematic in that the Skytrain without prior notice bypassed the Echo terminal so that delayed my arrival at my connecting flight.

It was a good flight. Of course it was full, but it went well.

Late boarding to clean plane from previous flight; initial boarding announcement not loud enough; fantastic cabin attendant front of plane

Delayed flight, few announcements with information, no comps, cluster f boarding because zones weren’t spread out and announced loud and repeatedly, staff did their job -nothing more nothing less, annoying kids were speaking and kicking the heck out of the back of my seat and parents weren’t willing to parent… so another typical day of air travel in the US.,

Gossipy flight attendants talked the whole flight about bar hopping and dating.

Turbulence was bad and flight attendants gossiped about going to the bar and dating. Could have better awareness.

On time and fast. Overall it was a pleasant experience.

3 hour delay was brutal though not Spirit Airlines fault. the control tower would not let us take off because of weather

Beware of all the extras. Nickel and dimed. Everything was extra. It turns a $90 fare in to a $400 fair quite easily.

It would have been nice to have been on the flight

Delayed several times. Flight was to arrive at midnight and it arrive at 3 am. A 3 hour delay is already bad but one that has you arriving in the wee hour is just disruptive and overall unacceptable. The complete lack of restitution is a joke in keeping with Spirit’s reputation of ranking bottom-low in the pecking order.

It wasn’t as horrible as I would have expected, however, to not provide water and change so much for bags is a ripoff to say the least.

The crew was great but it felt gross how spirit charges you for every little thing. Picking your seat should be free (first come first served). Beverages and food I get. But picking where I sit? Gross.

Cancelled my flight , currently stuck in Houston and will likely miss my cruise

The flight attendants were very personable, extremely friendly, and had a very good feeling of the energy around them not to mention they’re very funny and engaging. What made up for the discomfort of the seats and the fact that the plane sat for a long time on the Turmac. Not sure if the pilot was new, but the landing was very rough sort of like I was at a magic mountain theme park ride that was built in 1959

Unfortunately not great, my flight was canceled with no notice given. I attempted to reach out to spirit airlines and have yet to receive any correspondence. I then had to book a new flight at two times the cost of the original.
