Airline reviews

The weight limit per bag was really low - 40 lbs - so we had to pay extra. Then, they said their carry on size was 14x18x8, and we measured our bag very carefully. It was within the limit, yet they said it was too big, so we ended up paying an extra $100 for that too!! So it wasn’t the cheap flight we thought it would be. Then, they moved up our initial flight to depart 3 hours earlier which meant we had to be out on the road by 7 am and then have a 6 hour layover and we got home at 2am. It was a grueling day. I won’t be flying with them again.

Flight was canceled. Knew there was weather, and were notified of 20 min delayed, and then suddenly canceled. Next reschedule was for 2 days. No help other than to refund. Thankfully full refund and appreciate that. I appreciate discounted airline but felt they could've done more for customer inconvenience.

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.

Didn’t happen. They stranded us in Orlando and had to book a flight on frontier to get to our destination.

Our flight was changed from a direct flight at 7am to 10pm the night before with a 9 hr layover which we had 24 hr notice and then had to pay for a hotel room. I asked for one free carry on for the inconvenience and they said no.

Changing flights days after confirming an itenerary and moving a connecting flight to the next day which resulted in the layover extending from 2hrs to 10 hrs was a great inconvienience and burden to passenger

The plane itself felt old, rattled a lot, was louder than most planes, and made us so nauseous that our son vomited on both flights.

Check-in process was a nightmare. Boarding pass wouldn't show up in email. Had to have it printed at airport. Unclear if connecting flight was included in check-in process. Tons of pop-ups during check-in process; extra fees for everything, as well as attempts to get you to sign up for stuff. Such a misleading, gimicky operation... I won't fly with them again.

Seats could use more padding. Kind of hard on the tush.
