Pros: "I like that we eventually arrived at our destination."

Cons: "Missed connection and utterly dismal options!"
Pros: "Funny flight attendant on the way to Houston. Loved his sense of humor. Good price for ticket"
Cons: "Very cold in the plane Boarding crew at the gate - looked and sounded like they just got out of college. They need a better script/training for making announcements. No option to check-in online without signing up for Free Spirit. Guess bare minimum means many things..."
Cons: "Seats are horribly uncomfortable and did not recline"
Cons: "Two hour delay was very unfortunate because the link light rail stops running at midnight so I had to spend quite a bit more money for an Uber home"
Pros: "Low Price"
Cons: "High adder for seat and luggage. Very uncomfortable seats. Seats do not recline. Not enough leg room. No complementary snacks or drinks. After you add the unexpected luggage fees and seat fees Spirit would NOT be the best price! What a scam! I will definitely steer clear of this airlines after I complete this trip."
Pros: "They boarded quickly, the flight left and landed on time. The crew were friendly. I was glad that I had paid extra for a front seat, which was very comfortable."

Pros: "Crew is friendly"
Cons: "Seats are uncomfortable. They told us when we checked in that they were running on time. They sent an email saying we would arrive early. HA"
Pros: "Boarding was fast. The flight was on time and even landed sooner than what was quoted. The cabin smelled fresh, not like usual planes. The seats did not feel too gross."
Cons: "Two crew members (a flight attendant and perhaps a pilot) were SO loud during part of the flight that it triggered epileptic side effects for me (dizziness, extreme nausea). I threw up several times due to this. The crew members were not talking about essential flight needs, it was social. However, after I began vomiting the crew was quick to help me with extra bags, ginger ale, and dimming a light closer to me."
Cons: "The flight left 9 minutes earlier than scheduled so we missed the flight and had to go to hotel and missed a day at my job as well as my wife too."
Pros: "Very friendly crew"
Pros: "Customer service was phenomenal. Very happy with the price and service"
Pros: "we had a safe flight, no major issues, and were able to get off the plane quickly."
Cons: "I had to pay $97 to check my bag...kinda defeats the purpose of booking a cheap flight. This was by far the smallest seating space I've ever had...I'm 5'9 so normally I don't have an issue with this but my knees were about an inch away from the seat in front of me and I had no space to move around. The headrests were hard as a rock, and I could feel a metal bar in the middle of the seat poking out at my back. The seats don't go back, there was no entertainment whatsoever, not even a magazine to read. The main lights were left on during the 4.5 hour nighttime flight. There was not even a complimentary cup of water...$3 for water. It was also freezing in the plane and there was a 2 hour delay for no apparent reason. Look up the fees they charge for everything before you book with Spirit."
Cons: "Unprofessional cabin crew. Talking loudly while passengers were trying to sleep. It was a 10pm- 2am flight. Asked for help and lady told me to wait a moment, continued to talk to another cabin crew member before coming back to me."
Cons: "The flight was already delayed for over 1hr 30 min and then the Baggage handlers put the bags in the wrong place we had to go back to the gate and wait for them to move bags from the front to the back"
Cons: "The fact the flights got delayed because there were bad weather in Florida, when the flight was Houston Seattle."
Pros: "This was the shortest travel time from Houston to Seattle."
Cons: "Baggage policies, lack of USB or electrical outlets, limited food selections. If another airline offered a nonstop flight for an additional $100 I would gladly have paid more."
Pros: "Got to Seattle safely."
Cons: "Massively delayed. Overbooked flights"
Pros: "I liked the price. I got home safely."
Cons: "The flight attendants were straight up rude from start to finish. The seats didn't recline, meh. The A/C was non-existent and it was too warm. The flight was delayed for departure and once we landed, we spent almost an hour on the tarmac waiting for a gate to depart."
Cons: "Delayed 3 hours. I'm 6'6" seating in the middle seat. Never flying SPIRIT again."
Pros: "The temperature on the plane was perfect"
Cons: "Seats were not comfortable. It was my first time flying with spirit and once you pay extra for a seat, bags, and food, it ends up costing more to fly with this airline than it does with others. I will not be flying with spirit again."
Pros: "Low price, left/arrived on time, friendly crew."
Cons: "High Carry-on fee, tight leg room, non reclining seats."
Cons: "It was too cold."
Cons: "Our flight was canceled due to "weather" but other flights were taking off. Really messed with our trip and we will never fly with Spirit again."
Pros: "The whole experience was absolutely wonderful. I will fly spirit as often as I can for the destinations I fly to. Great service, and very importantly to me, very good to active duty military and veterans. Big thumbs up!"
Pros: "The schedule. Departure and Arrival."
Cons: "Was difficult for the person that was supposed to pick me up to find me at the airport."
Pros: "We got to our destination safely"
Cons: "The line, the payment for luggage, arrived late"
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. The lady a the boarding brigde wanted a 100 dollars just becuase we had 1 hand bag. Pure cheating."
Cons: "I had to cancel at the last minute. No refund or credit."
