Flight attendants very hospitable and friendly. Pilot flew a smooth take off and landing.

Paid for premium extra leg room but the bin space for rows 1-3 had to go in rows 4-6 and 4-6 had to go to 7-9 because flight attendants have snacks and their luggage upfront. So we pay extra to have to fight thru traffic to get our bags. Only 2nd day of new seating so hope they fix this.

WIFI was great. My selection for seating is an aisle, but during my trip, I never had an aisle seat. If we can get that corrected, I will be thrilled. No snack or drink on this flight.

WIFI was great. My selection for seating is an aisle, but during my trip, I never had an aisle seat. If we can get that corrected, I will be thrilled.

The wifi on the plane is great. The only issue that I have is that I prefer an aisle seat and on my trips this week, I was either in the middle or window. If we can work to secure aisle seating, I will be thrilled. Nice trip.

All good except once again bags took an hour at Midway Airport Happens all the time. Ridiculous

Everything went smoothly and we even arrived a little bit early.

Great vacation. Can't wait till next year for another one.

Great flight but super high price. Glad it was a business trip and not personal

On time. Friendly staff. Took to long to pre bord all the specialty groups. Cramped small plane

Update to handle the delay was very bad, crews no smiles or welcome or thanks. Don’t care attitude

It would be nice to have some low carb options in the snacks.

I was trying to take 2 one and a half hour one way trips and I experienced almost 20 delays over the course of those two trips. Only a few of them were due to weather the rest was disorganization

No gates avail at DFW so our incoming had to wait 30 mins for a plane to push back because they Had mechanical. We boarded 90 mins delayed and then we had a mechanical. Come on American…do better. Also at my seat the tray table had not been cleaned. Floor had not been cleaned. But captain and flight Att were very picture and apologetic.

Crew was helpful and cheerful especially when they had no refreshments to work with. The plane was never serviced and had nothing but limited water and coffee onboard. For the price point, a concern of services.

Flight was smooth, quick and felt safe. The 2 delays not happening would have been better but I guess that happens in the airline industry

Flight was canceled. I asked to be rerouted to OKC and then took an Uber.

AA did not allow to board a flight because my connecting flight from DFW had been canceled. I got on another flight to another city. No service on the plane and I did not use their entertainment system.

On time on a day with lots of weather cancellations on other flights. Thank you for getting me home during a winter storm!

Don't change gate multiple times make people run across the airport. Announce delays in a timely manner. Have maintenance crew ready. Don't delay and keep passengers on the plane for 3 hrs. on tarmac.

It was smooth sailing snags we had a really smooth landing and a great flight!

Flight was cancelled with very little notice. Had to scramble to find transportation to my Mexico vacation.

Every Spirit flight we took was delayed by nearly 2 hours. We arrived in MCO and learned that our connection had been canceled. There were no options for rebooking for 4 days. No hotel vouchers provided, no transportation etc. The airline essentially stranded us, and rhe passengers from 6 other flights hours from our destinations with no assistance. Still no word on my refund. Terrible customer service.

AWFUL THEY CANCELED MY FLIGHT LESS THAN 12 HOURS BEFORE AND GAVE NO WAY TO GET A REFUND OR BOOK A NEW FLIGHT. THEN HAD THE AUDACITY TO GIVE ME A $30 VOUCHER ON A $500 FLIGHT

We had too many delays for the crew not the plane

Spirit cancelled the flight very late last night, I was on the way to the airport when I found out

Horrible. Arrived at my gate at 6:37 for a 6:50 flight and was denied by staff to board. Literally watched my flight leave from the window and it didn’t take off until after 7am. Tried to talk to staff and they were rude beyond compare. Will never fly with this airline again.

It was a no show, so we got put in hotels for a nite. The A320 plane was very modern and flite and crew (if a pilot shows up were fine). Price was very good.

Had a issue with catching flight due to airline, was unable to board flight

Better than my las vagas experience, but still dissapointed with the airline support service.
