Delayed..4 times...completely disorganized boarding. After 5 hours they scrambled to move ppl off plane bc they overbooked. Then they didn't have a cabin crew. WiFi on plane didn't work. Zero amenities. Once we boarded we sat on tarmac for an hour. Explore all alternate options including purchasing a pair of hiking boots and walking to your destination instead of flying spirit.

The seat was very uncomfortable from Boston to Nashville. Otherwise the flight was excellent.

Our flight was delayed two hours. We nearly missed our connecting flight and had to rush across the airport with little kids and all their luggage. They didn’t give us enough time to walk from one gate to the other, then when we got on, we waited another half hour while the crew loaded cargo. It seems like they could have given passengers more time if they had cargo to load anyway.

I had a phobia for Spirit and now is 100% confirmed. Flight delayed, missed connecting flight and staying overnight . Now not even able to get my boarding pass until I’ll get into the airport. It’s really really bad at this point

the landing was terrible. the plane touched down and had take off. the plane flew around and landed a second time.i understand the weather might of been the problem. It was a scary experience and no explanation from the captain.

Service was awesome 👍🙏 thank you Spirit Airlines...love the Big Seat...😎

Crew was very engaging and welcoming. Seat very uncomfortable and inadequate leg room made the trip a long 3 hours.

Plane two hours late. Missed flight to Boston. Spirit should have already reticketed us at the last jet blue flight. But no. No help, only confusion. Reticketing line a mile long. Agent couldn’t care less whether I lived or died. Offered flight two days later - unacceptable. Now going - hopefully - via Orlando to Boston with a 7 hour layover. Locator GJLSJG BTW, am a travel counselor at a large corporate agency.

There are additional charges for everything including water. If you are unwilling to pay additional charges you are afforded no comfort at all. Seats are smaller than other airlines and do not recline. Schedule changes appear to be customary because you encounter them on departure and return.

The flight was delayed. The boarding process disorganized. Poor communication regarding the delays. We were sitting on the runway in Boston for over 1-hr. Again very poor communication regarding the status. Bags didn’t arrive after almost 2-hr wait. I gave up and went home without my bag and had to return to the airport to pick it up the next day. Very exhausting experience!
