Pros: "The male steward was very nice"
Cons: "Flight was delayed on tarmac for 2 hours better communication"

Cons: "Delayed boarding but received notification from Kayak was good."

Pros: "Friendly crew. Great movie selection through gogo inflight entertainment!"

Pros: "Aircraft was clean and comfortable. Crew was efficient and friendly. The whole experience was excellent!"
Cons: "There was lots of entertainment available but plain old music was not an option. What if I don't want to watch a movie or TV, just listen to music!"

Cons: "Seat cushions are too thin."

Pros: "Great on time too"
Cons: "Very happy"

Pros: "The seat was comfortable and the plane wasn’t over booked."
Cons: "I didn’t like that we took off an hour late."

Cons: "Two rows up from us, I kid threw up all over the center aisle as we were pulling away from the gate. We returned to the gate to allow a cleaning crew to board and clean. However, the cleaning job was rushed and left remnants of the throw up behind which smelled the whole 2.5 hour flight. It really felt unsanitary and unsafe being that it’s unknown what caused the child to get sick. It very well could have been a stomach virus and could have infected the people in rows around the incident due to the mediocre cleaning job. I understand that it’s important to keep flights on-time, especially for connecting flights, but the safety of the passengers and their health should ALWAYS be the #1 priority."

Cons: "Gogoinflight didn't work for at least the first 30 minutes of flight. I upgraded to first class, but there was no service until we were above 10,000 feet. I don't know if this was a one-time thing, or if other airlines are just better at accommodating first class."

Cons: "So many bags that were suppose to go under the seat infront of you that weren't. So that those of us that boarded last had to wait while stewarts removed small carry ons. So that our one carry on that fit in the box but not under the seat could be stowed. It would be nice if the smalls bags that are to be stowed under the seat were. The family next to me had 9 bags in the over head. There were two adults and two children 3 and 4."

Pros: "I like the efficiency and the price of frontier flights."
Cons: "I don't like that it is very cramped and it is hard to get comfortable. Also you have to pay for non alcoholic beverages which is annoying. As well as the fees for luggage and seat assignments. Overall they were still cheaper than the other flights available, but it is false advertising to initially pay such low fares but then upon check in have to fork over another $60+ for bags and seats. Felt sort of scammed"

Pros: "Sort of cheap"
Cons: "Cheap at every level. Makes you feel unsafe. Are they cutting on cheap pilots too?"

Pros: "The horror started in LA standing for over an hour before a ticket employee came to check us in and take our bags.

Cons: "Flights delayed multiple times both ways."

Cons: "I got to Denver safe-thank you"

Pros: "It was cheap, comfortable and safe. I would use this airline again."
Cons: "The sits can't move back to lay back. Please change that."

Cons: "Basically Spirit airlines is deceiving the customers when you play the ticket price game. Everything is an add on. Really?? I have to pay more to select my own seat? The final price of the ticket did not compare to other prices I could have gotten, but since I never flew Spirit I was unaware. I will never fly your airlines again."

Pros: "All was great but the extra large seat did not recline?"

Pros: "Absolutely nothing"
Cons: "They nickel and dime you to death. Just horrible. The ghetto of airlines"

Cons: "Wasn't clear when purchasing tickets that carry on would be 40 something extra per way. Also that snacks and drinks would cost. And no reclining option for chairs. Would have factored into my decision. Would have like to have known that beforehand so I would not feel nickel and dimed. Otherwise - it was a good experience."

Pros: "Not crashing"
Cons: "Late schedule, last bags, rude airport personnel"

Pros: "Nothing"
Cons: "Everything"

Cons: "I was not informed of the 45 min check in cut off, and so Lost hundreds of dollars. I will never use your site again."

Pros: "the service was wonderful, the l8nes wwnt by quickly"

Pros: "We didn't crash"
Cons: "Everything else"

Pros: "Nothing, although the air was breathable, so could have been worse"
Cons: "Bag charges thru the roof, charge for coffee (that tasted terrible as well), ticket change policies, etc, etc"

Cons: "I don't like being nickled and dimed. If you need to charge more for the airline ticket instead of charging for 1 bag, I would much rather prefer that."

Pros: "Everything"
Cons: "No complaints"

Cons: "Several delays, Lax staff for Spirit airlines need better customer service skills."

Pros: "everyone was personable friendly, and professional."
Cons: "the were no peanuts."

Cons: "No complamintry snacks"

Cons: "After making the reservation I tried to call to make an adjustment and your website is the worst I have seen in quite sometime and completely worhtless as far as making changes and much less trying to reach someone for assistance. NEVER WILL I CONSIDER THIS AIRLINE AGAIN AND WILL GLADLY TELL EVERYONE I CAN ABOUT IT."

Cons: "On the sight online does not tell you that you have to pay for each baggage $50 dollars people should know that! !!!!so they would not be surprise .At cheking in my parents the lady wasn't as nice just because we didn't know that we have to check in on one of the machines! !!!not a good experience!"

Pros: "NOTHING."
Cons: "$100 to bring a bag on board. The worst!!!"
