Pros: "Crew was entertaining, but that didn’t make up for the flight being dry, stuffy and uncomfortable."
Cons: "Having a minimum a 20 degree seat shift would’ve been nice, but flying spirit I guess you can ask for the world."

Pros: "Nothing really was standing out to like."
Cons: "Flight was late by one how which resulted in problems with car rental. Non standard weight limit for checked bag. It used to be ~50lb on all flights, it's 40lb on Sprint. I did not have to pay, it's just more packing effort. Spirit seems to try to sell everything, even if it's included already. To select a seat (any seat) I would have to pay ~$20. If I do not select I'll get it anyway. Seats could not be reclined. No entertainment."

Pros: "Safe travels. Good crew."
Cons: "Comfort is not good at all."

Pros: "That they didn’t cancel the flight"
Cons: "Staff didn’t care. Boarding was terrible. Delayed without communication. Didn’t have a gate open when we landed at 1am"

Pros: "Loading was quick"
Cons: "Unloading was very slow"

Pros: "Everyone was so polite"
Cons: "They do not give free soda and cookies no more"

Pros: "Nothing at all"
Cons: "Who bumps you off a domestic flight if you're not already checked into 2 hours ahead of time? Spirit that's who. The adage is true, you get what you pay for. We paid for a scam with spirit. They apparently have an odd policing if you haven't checked in at the airport 2 hours ahead of your flight, you don't get to fly. No one alerted us to this policy and spirit even double down on the claim the my didn't have our contact information to alert us while I was actively receiving texts from them. Did nothing to try and help us. Pay more elsewhere. It will save you in he long run."

Pros: "on time, staff"
Cons: "plane uncomfortable, small seating. no beverages or snack included. extra cost for luggage that put price point over the top when comparing to other airlines"

Pros: "Cost"
Cons: "Seating - seats did not recline & were too close to the seats in the row in front of our row. A bottle of water was $3. Will not fly this airline again!"

Cons: "Seats don't recline at all , late departure"

Pros: "Cheap airline ticket"
Cons: "$52 checked bag Non reclining seat No drink/snack Late"

Pros: "Comfortable seats. Safe arrival."
Cons: "I used the bag measuring mechanism to determine if I should pay. My bag was about 2 inches too long. I paid the 50$ but observed that many folks had similar bags in the overhead compartment. Then, my son laughed and said that most people pay no attention to the measuring device. Oh well, lesson learned."

Cons: "Never flying spirit again"

Cons: "I hate the spirit model and I hate that the regular airlines are starting to do it. Also they don't put enough padding on the seats, which is uncomfortable on a 5 hour flight. Flight was overbooked so it left late, but they padded the arrival time by an ENTIRE HOUR so it arrived "early"."

Pros: "Nothing"
Cons: "Charged way too much for bags, seats so uncomfortable with half a tray table, no drink offered to me besides for purchase during flight, delay of over 2 hours all day long- why couldn't this be resolved in 8 he window? unacceptable."

Cons: "Last minute cancel"

Pros: "Pretty miserable flying experience."

Pros: "Uncomfortable seats, zero leg room, a website that has yet to function properly without me having to call customer service several times per flight. Not to mention the "Low fares" Spirit offers you don't actually account for the money you shovel out for EVERY SINGLE EXTRA you can think of. I ended up spending 65$ on my last flight just to bring a carry on and choose a seat. Tie that all together with an angry, impatient, and unprofessional staff, and you result in a customer who will never be flying spirit airlines again."

Pros: "While my bag was left in Boston, they eventually delivered it to my door on New Year's Eve."
Cons: "Both flights were delayed, yet the airline still managed to leave my bag in Boston. When it didn't arrive in Oakland, they couldn't tell me if they had left it in Boston or in Las Vegas, and it was only through how long it took the bag to arrive that I figured it out. They were responsive at the ticket counter, and gave me the number of the baggage office to call to figure out where my bag was. The baggage office, however, never answered their phone nor did they return my first 2 messages. When I called the main customer service line, they could tell me nothing beyond the phone number for the Oakland baggage office, which I already had, and was not returning my phone calls. Eventually, my bag was delivered to my house, but it took about 48 hours from when I landed for me to get my bag back."

Pros: "Spirit delayed flight 6 times before ulimately canceling the flight hours after it was supposed to take off due to "mechanical issues.""
Cons: "Everything"

Cons: "Horrible"

Pros: "Nothing"
Cons: "Delay in flight, horrible service, delay getting baggage"

Cons: "No leg space. Not even offered water."

Pros: "Efficient, fast"
Cons: "Seats don't recline."

Cons: "No wifi"

Cons: "Delayed.... Delayed... Delayed"

Pros: "Pleasant flight attendants"
Cons: "Individual costs for everything, most uncomfortable seats ever, had to pay extra for services I never even received, confusing and frustrating registration process ... Nothing was positive about this experience!"

Cons: "The flight was 3h late and not only they did not apologize but didn't even offer anything while flying. Even waiting for the baggage is being awful, we landed 30' ago and it is not here yet"

Pros: "They did give me a sick bag for free. Correction: they did give me a trash bag to use as a sick bag for free...."
Cons: "Not sure why the tray table were so small, basically enough room to hold a drink or write a cheque... The seats do not recline so a bit uncomfortable especially on red eye or longer flights. Flights almost always delayed. Baggage fees, fees for everything. No complimentary refreshment."

Cons: "- I didn't realize you have to pay for carry-ons - more than usual nickle and diming - least comfortable seat I've had on a plane"

Cons: "You get what you pay for..."

Cons: "Babbage fees"

Pros: "Nothing"
Cons: "Everything, everything is about money and nothing is about the customer"

Cons: "Will never fly Spirit again."

Cons: "Customer service was terrible."

Pros: "Airfare"
Cons: "Seats very uncomfortable"

Pros: "I got the whole row to myself!"

Cons: "Seats do not recline and no wifi!! Additionally you pay for everything from carry on and water!! Will never fly Spirit again."

Pros: "It was easy to board"
Cons: "Not even offered water. Both departing and arriving flights were late by over an hour the departing flight was late by two hours. Unless there is no other choice I will never fly on Spirit again. I am a retired high school teacher and you guys get an F. It is the worst experience I ever have had on an Air Line In my life time I have traveled over a million miles"

Pros: "Direct flight, convenient times"
Cons: "All the extra costs for every little thing. Uncomfortable seats"

Cons: "this could not have been more terrible in any way, awful food crew service. flight delayed 4 hours and then we say on the plane at the gate for an additional 2 hours before take off. no explanation was given for the delay at any time. baggage fees we not advertised anywhere at any point prior to arriving at the airport. had i know about the bag fees flying literally any other airline would have been cheaper than this bogus "discount" airline."

Pros: "I enjoyed landing in Las Vegas that's about it."
Cons: "There was a lack of comfort, lack of space, and lack of entertainment. The only thing that I didn't charged for was breathing and I appreciate that."

Pros: "I like how quickly the plane emptied out from the incoming flight so we could board faster."
Cons: "Didn't like the hidden fees, didn't like the cramped seats that fail to recline at all. Didn't like the surprise cancellation three hrs before my flight and having to scramble to make arrangements, tho I will give Spirit credit for putting me in a decent hotel. I will still use this airline for trips to Costa Rica but will fly blue for all domestic flights."

Cons: "Surprise bag fees higher than advertised online. The whole process is obviously designed to price gouge. The flight ran out of all whiskey and scotch less than two hours in."

Pros: "Literally the only good thing about my experience was that the flight attendants were excellent."
Cons: "They trick you into thinking the fare is cheap, but they nickle and dime you. One 50lb bag and one carry on and a purse cost me $137 to check. Yes, that's right, they charge your for a CARRY ON and their bag weight limit is 40lbs! If your flight gets delayed and you miss a connection it will likely be days later (4 days in my experience ) before they can fly you home and they will fight you on any sort of refund or compensation."

Cons: "THEY SUCK"

Pros: "Nothing!"
Cons: "They charged $50.00 for one small bag to check in and they lost it. All my belonging is in that bag for this trip. What am I going to do now?"

Cons: "Left 1 hour late Very noisy"
