Pros: "Great machine"

Cons: "Spirit is a horrid airline. The counter people were rude the flight crew was rude and unprofessional. The spoke about passengers that were in ear shot of them. They were just plain rude to customers"

Pros: "The crew was awesome!!"
Cons: "After buying my ticket, a day before boarding, I was charged separately for checking bags and carry-ones. Once I got to the airport, I was charged another $30 for the weight of my bag. I should have been made aware of these fees during the purchase of my ticket. Nearly $200 unexpectly taken away from my vacation fund. Soooo not cool. I believed I was getting a great deal, but in actuality I was being charged just as much as any other flight. The ride may have been better with another airline because the seats where compact, hard, and immobile. It’s definitely was my best experience."

Pros: "Pilot was very nice and entertaining"

Pros: "1st time trying your airline"
Cons: "Hidden fees, delays, baggage fees cost more than plane ticket. I was not told of extra cost to check in at airport. There was no update of delay, no passenger knew anything. Very disappointing."

Cons: "Noisy flight attendants constantly slamming and banging things in the galley. Trying to sleep while sitting bolt upright is hard enough without all that noise."

Pros: "Flight was as expected."
Cons: "Handling of the 5 hour hour delay. Delays are normal and I appreciate the attention to safety. After we deplaned, I would have liked more information. Everybody in line asked the same question - when’s the next flight? The worst part was the delay with meal vouchers. They said they were going to read off the names, when I saw them flipping through and not reading the names, I asked why, to which they responded “because it’s hard to read”. Well, they aren’t going to read themselves. Either try, or spell it out. Or call out confirmation numbers. Eventually they got them mixed up, gave up, and asked us to come up 1 at a time so they could find ours."

Pros: "The price"
Cons: "Stewardess were really cool"

Pros: "Good price"
Cons: "Couldn’t even get water without paying for it. No in-flight meals offered, no blankets or pillows, no entertainment whatsoever."

Cons: "First time flyer with Spirit, overall bad experience. Our flight was delayed due to weather, they didn’t tell us what the problem was after 2 hours stuck in the plane at the gate. It’s expensive with all its add ons. You have to pay for carry on, seating, they don’t offer water, as basic as water you have to pay for it!! No entertainment No WiFi No charging outlets. Old planes. Never ever again will I give them my money."

Pros: "Nothing"
Cons: "The dont have it anywere during booking process that not a single bag will be allowed onboard. (i mean even a hand baggage). After that they say that they have it mentioned on the boarding pass. I dont think anyone reads that in particular. More over when i checked the lady did not have a problem.
