Flew first class so everything was great. But maybe because the flights were red eye, no meals were served, just chips. I flew Alaska Air 1st class at 9PM (2 hour flight) and they served beef short rib sliders!

Flew first class so everything was great. But maybe because the flights were red eye, no meals were served, just chips. I flew Alaska Air 1st class at 9PM (2 hour flight) and they served beef short rib sliders!

Had to change aircraft due to a faulty door. Surprisingly it only caused about an hour and a half of delay. Delta handled this situation as well as can be expected.

Paid premium for Delta only to be on safe but tired old 767 with ancient cabin in mediocre condition. Poor wifi and horrible inflight entertainment. Hardly a premium experience. Should have flown SW and had fun flight crew and no pretense

Half the bathrooms assigned to economy were out of action

Carly the flight attendant was extremely helpful and very accommodating to passengers on the flight from what I noticed. Couldn't be more satisfied with the service and assistance from Delta's flight attendant, Thanks again Carly!!

Had to run to make it only to have the flight delayed to wait for all the late connectors Second drink service skipped up

It wasn't really their fault it was the horrible winds and we just got unlucky.

There is no free Wi-Fi or screens in the seats for this flight. It would be nice if they had actual actual healthy drink options like a flavored sparkling water. The flight was very dark because nobody was sitting on the left side and they didn't open any of the windows. The plane was kind of and had small overhead bins. There was no distinguishable difference between economy and comfort Plus.

I recently had foot surgery and traveled my first time needing assistance. The flight attendants on this flight went above and beyond accommodating my partner and I. I had a panic attack from the medication I was on, and the flight attendants made me feel safe and comfortable when they saw me in distress. They relocated me to an area of the aircraft that made me feel more comfortable and we had our own row which helped reduce my anxiety tremendously.

On time departure and early arrival. Excellent customer service from flight crew

This was the smoothest flight I have had in awhile. I was also offered an exit row seat for a great upgrade cost and was able to sleep almost thr whole flight due to comfort and a smooth flight. We left on time and arrived on time.

No food not even water offered unless you buy it and no usb in the seat but other than that everything was good

Because our flight from marsh Harbor to Fort Lauderdale was over three hours delayed it caused us to miss our flight in Fort Lauderdale. Because we missed that flight, it cost us nearly $100 apiece for four different travelers which totaled nearly $400. We are seeking a reimbursement for the flight that we missed in Fort Lauderdale Florida.

Flight expected to leave at 6:40 pm ended leaving at 8:00 am the following day. I slept in a cold airport. Never again Spirit for me…

The flight was on time and nice as always for me with spirit but the cabin crew were not good. They left the lights on on a red eye for the entire flight.

This was the return leg of my journey with Spirit Airlines. Despite its reputation, I found no issues as it got me from point A to B safely and without delay, especially with no mechanical delays, which is fantastic in my book! The staff, from ground crew to cabin crew, were all pleasant and hassle-free. The flight was smooth from takeoff to landing. I have absolutely no complaints about this no-frills airline!

I got a one-way, last-minute nonstop flight from PDX to BWI for only $125. Yes, I got nicked $79 more for a checked suitcase and $89 more for the BIG SEAT option, but it was worth it, even with $4.50 for coffee and $10 for a snack (the latter no different than any other airline). The grand total was still less flying on any other airline.

It was the worst ever, i will be filing a lawsuit to get a refund. Our flight was delayed 4 hours so we would miss our connecting flight, we were not rebooked to our destination the same day, we were not offered any options to get home on the same day despite being clear that we absolutely cannot get stranded at night due to family, we were forced to book our own flights on a different airline to get home, and spririt is refusing a refund because our flight wasn't cancelled, only delayed. oh yeah, and they lost our luggage on the first part of the trip and you cannot get a hold of customer service when anything goes wrong, on hold for 30+ minutes. and their app breaks so you can't use that either.

This recognisable no-frills airline gets me from point-A to point-B. I was able to get to Chicago without stress. The checked baggage collection and reclaim could be improved.

The crew was the best and very accommodating I know you don't offer any complimentary items but water and coffee will not break the bank !!
