Cons: "I am a 5'3" 125# woman who, unfortunately, had a middle seat assignment. The passenger to my right, on the aisle, weighed approximately 375# and took up 1/3 of my seat. The arm was not able to go down comfortably, and when it did it was not usable . The passenger on my left, window seat, was probably 6'7" and had to sit with a man spread in order to fit. I could not move and was extremely uncomfortable. The plane was overbooked so I was unable to move. Therefore, worst flight ever. Plus, I paid for a full seat and was only able to occupy half of it."

Cons: "The flight was delayed due to several mechanical issues but the ground crew did not communicate effectively on the issue or how long the delay would be.

Cons: "Don't do it. Don't fly Frontier. Business model does not provide real training for the staff. No contingency plans for aircraft failures; no training for staff to handle day-to-day normal flights variances (aka, downed aircraft, weather, airport delays). Had three delayed flights trying to leave out of the same gate, instead of separating angry, tired, hungry passengers, they kept them all in the same gate which heightened tensions. Potential crisis situation only made worse."

Cons: "No free soft drinks.."

Pros: "Cheap..."
Cons: "Delaaaays"

Pros: "Made up time in the air"
Cons: "Flight was delayed half an hour"

Pros: "No service issues. Our seats were arranged so the family was together for no charge. We were given a bottle of water to mix baby formula for no charge."
Cons: "Hard seats"

Cons: "Bag was lost. Office doesn’t answer the phone when I can to find it. It’s been ridiculous."

Cons: "Very late."

Pros: "That the pilot gave us an account of why the plane hadn’t taken off when it should have. he also told us if the great things coming with spirit airlines. The ticket agent let go the fact that despite my removing items from my suitcase it still remained heavy. I felt like he cared. It put a great smile on my face. I felt special as opposed to being nicked and dined like I usually feel with Sprit."
Cons: "Being nickeled and dinmed. Paying $3. for a can of soda."

Pros: "Flew spirit a few years ago to Vegas and had an awful experience. I will say this experience was much better. I will now continue to consider spirit airlines for my travel."

Pros: "Spirit doesn’t have screens at the airport to tell you which gate they are flying out of - must cost too much - only American airlines has them and i thought they were for the whole airport - how can you tell? so i went to the gate that said san diego - the only one. waited in line. find out as near the last one to board that i was at the wrong gate."
Cons: "had to run to my flight leaving at the same time about 10 minutes away in an by running. Didn’t make it and Spirit only flies to San Diego once a day. So i miss Thanksgiving dinner with my family. So i have to go back to my apartment, an hour by subway, and come back tomorrow. First and last time flying with Spirit."

Pros: "The snack selection on the flight and food package options were reasonably priced, and there were quite a few good options."
Cons: "We arrived at the airport and were through security over an hour prior to our flight's takeoff. We decided to grab breakfast at a restaurant approximately 2-3 gates down from our gate. We arrived back at our gate 17 minutes prior to the departure time and the door to the entryway was already closed. No spirit attendants remained at the gate to assist or inform us about who we should speak to regarding this matter. We sat at the gate and watched our flight take over 15 minutes to pull away from entryway with no one available to direct us. After the plane pulled away, a few Spirit staff members came back out the door to the gate, and when we inquired as to why our names were not called throughout the airport (as we heard many other names called while sitting at the airport) they informed us we would have to talk to the customer service desk if we had an issue. We went to the customer service desk and they put us on another flight, which did not depart until late that day. We went to the customer service desks of 3 other airlines attempting to find a sooner flight, and when we explained Spirit closed the gates 17 minutes early, each airline stated that the industry standard is 10 minutes. Not only does Spirit not follow the industry standard, but they also shut the gates 2minutes prior to Spirit's standard which is 15 minutes before the flight. Additionally, no effort was made to call our names prior to the flight, as is customary with all airlines. Two days later, we went to board our return flight, which a week prior to our trip we paid $585 to change to that day, and when we went to check in we were not scheduled to be on that return flight. We showed proof of switching our flight and luckily the attendant was able to get us on that flight, however, we were extremely rushed getting through security and due to Spirit's mistake almost missed this flight as well. If no seats would have been available we would not have been able to get home despite paying to switch the flight a week in advanced. Overall, we were very disappointed with our experience traveling with Spirit and would not recommend the airline to anyone. We are frequent travelers for both business and recreation and have never experienced such poor customer service."

Cons: "That I missed a flight"

Pros: "No way to contact wheelchair assistance when being dropped of to begin flight. Waited 30 minuted for a wheelchair. Had to ask Amer.Air agent for help. Other airlines are far more attentive. Seats need 2 more inches, felt squished. Very costly baggage policy, charge for carry- ons."

Pros: "Nothing interesting to share or comment on this"
Cons: "Sprit Airlines has charged me additional $52 for cabin luggage, which is very high when compare to other airline operators. The service is very poor even for water it is charged, for such a long trip from Chicago to San Diego. Seating are very bad ...."

Cons: "Terminal at Chicago was disorganized, crowded,. Flight left late. Even arriving in Chicago was crazy as as getting off the plane we had to take a long detour winding through barricades on the runway, through two buildings, up a flight of stairs, before finally reaching an almost standing room only boarding area."

Pros: "I wish I had known that they charge BOTH for carrying on AND for checking a bag. I probably would have spent more money to fly a different airline in more comfort. I wish Kayak had made that a little clearer."

Pros: "Prompt, took off on time. Seat was excellent."
Cons: "Nothing comes to mind"

Pros: "easy and on time"

Cons: "Flight 3 hrs late. We were never told what was going on until it had already been almost 2 hrs, just kept receiving delay emails. Keeping the passengers informed would have cut down the tension and anger. No monitors in the terminal or at gates in o hare. Terminal dirty. Customer service personnel in o hare very, very rude. I will never fly them again. With all the extra charges they add on it is not cheaper either."

Pros: "The flight was great, the flight attendants also were very helpful and very nice great personalities which is always nice to find. Overall the four-hour experience was a nice experience thank you spirit"

Pros: "Everything and everyone were excellent. I was pleasantly surprised."

Pros: "Being tall, I like the fact that the seats can't recline; it means the person sitting in front of me can't put his head in my lap and stare into my eyes the way he can on other airlines."
Cons: "I will be more careful figuring out the effective price of a ticket on Spirit next time, knowing now that checking in a bag costs so much. I tend to think that this isn't a very good policy -- it just encourages people to drag more stuff into the cabin than they should or otherwise would."

Cons: "Mechanical issues. Initially, airline tried to fly with a fuel leak, until they learned the fuel leak was not within the plane manufacturer's tolerance for safety. They then made me wait 9 hours in the airport for them to bring another plane. It appears that they delayed flying in a new plane until after they tried to fix the fuel leak for approximately 2-3 hours. At the end of this ordeal, they provided only a $50 credit for their airline and a $7 voucher to buy a coffee in the airport. I will never fly this airline again."

Pros: "Boarding seemed to be non-problematic and without delay. The flight crew was nice/animated. I would suggest this airline for flights that are less than 1-2 hours and not a flight across the country for the cheapness. Caveat is you pay for carry-ons, but just pay in advance (onine)."
Cons: "The tray tables could accommodate two drinks next to each other and were not full-sized tables. So glad I did not bring my laptop as I would not have had ample space on the table to set it. Seats don't recline. Again, all things considered, you really do get what you pay for."

Pros: "It's over"
Cons: "$$for carry on, cost for H20. 30 min late. Bad customer service"

Cons: "I wasn't aware I had to pat for bags for both a inbound and outbound Flight. The economic Flight all of sudden turned into a premium price where at minimum I would at least gotten a free water. Never booking on Spirit again."

Pros: "The flight was on time."
Cons: "$30 service charge because we needed help with my 92 yr old mother-in-law and had to talk to an agent. Never again will we travel Spirit."

Pros: "Nothing"
Cons: "The seats don't recline at all, and they are so narrow, you can't avoid hitting or rubbing against your neighbor. Very claustrophobic. I hated that they hawked the "Spirit Credit Card" when we passengers were jam-packed into the plane with no amenities for 4 hours. Just bad."

Pros: "Flight was smooth"
Cons: "too many charges. Luggage took about 35-40 min to come out."

Pros: "Flight attented were nice"
Cons: "Delayed 45 min waiting 4 a crew member. On time to arrive but it was unprofessional we had to wait. Sits are bad, don't even go back"

Cons: "Everything"

Cons: "SEATS VERY UNCOMFORTABLE CAN'T EVEN HAVE A GLASS OF WATER WITHOUT PAYING FOR IT WILL NEVER FLY SPIRIT AGAIN AND THE PLANE WAS DIRTY"

Pros: "Space under the seat fit my backpack luckily."
Cons: "Baggage policy, everything had to be paid for, I ended up sittingin the middle, arrival time was delayed."

Pros: "The plane"
Cons: "The plane"

Pros: "Nothing"
Cons: "Seats are ungodly uncomfortable, they done recline and hardly any cushioning"

Cons: "Baggage restrictions are ridiculous. Especially that your checked bag can't be more than 50 lbs, and that before I booked a spirit flight I called to make sure that my checked baggage would be free of charge, as I am a military spouse. I was told it would be, but then during online check in I was told that it was not. I would not have booked with spirit if I had known this in advance."

Pros: "Smooth flight"
Cons: "Had to move seat because of other passengers issue but was not compensated and my car reservation was not made"

Pros: "nothing"
Cons: "the baggage fees check process took too long not enough ground staff to make check in process faster or efficient on flight staff unfriendly"

Pros: "Free upgrade to emergency row."
Cons: "Nothing."

Pros: "The flight was fine"
Cons: "The check in at ohare before going through security was terrible. There was a line of 6 people and 3 people working the counter- it took over a half hour. They were extremely slow, unmotivated, and overall unpleasant. They were rude, telling me I showed up late and that I should have showed up at the original flight time even though I had gotten an email that morning staying my flight was delayed. I'm not sure why you would show up for the original flight time when your company emails the passengers to notify everyone the flight is late."

Cons: "Spirit is very difficult to deal with. If you have any problems it will snowball out of control quickly because of their poor customer service."

Pros: "On time"
Cons: "No consideration for disabled"

Pros: "Low cost at first look."
Cons: "Way to many potential fees or up-charges."

Cons: "Spirit Airlines boarding staff were not engaged with their work at the boarding gate. Did not give final boarding call notification. Prevented us from boarding while the plane was docked. Did not assist us in rescheduling our flight after it debarked without us. Did not let us know the necessity of confirming our return flight. Furthermore, the policy of cancelling someone's reservation for their return flight automatically after they miss their initial flight, without informing them via text or email, despite them checking in within the 24 hour period prior to its departure is a morally bankrupt practice that is highly detrimental to building customer rapport. It is also bad for the bottom line of the business as it ensures confusion and customer dissatisfaction. While it is financially desirable in the short term to over book flights and cancel flight reservations without a refund or notice, it is in the long run detrimental to the company as it guarantees wasted time and resources for the airline and the consumer. You must do better with the communication between passenger and airline, you need to post the boarding time, the gate closure time, and the departure time clearly on the tickets customers print. You also need to text or email confirmation and cancellation information. And you must have energetic staff at the gate who are interested in performing the routine work of gate stewards. These are mandatory changes that must occur. They are not suggestions. Basic customer service functionality is required of any transportation service. It is not something you can include when you feel like it if the customer pays extra."

Cons: "The gate agents in Chicagp were rude and gave us incorrect information. They were chatting with their friends instead of answering our question. Then she told us we could use a different security line. When we went over there, we were told if we were flying spirit we had to use the long one on the other side of the airport! Our flight was then delayed twice, when we asked for an update, the gate agent was again rude, though she did eventually tell there was something wrong with the floor of the plane. Once we were on the plane, we were stuck on it for another 45 minutes before we took off. Baggage claim in Chicago was also a mess. There was only one carasaul and it took about an hour to get our bags. Our ride had to circle for an hour. We will not be flying spirit again."

Pros: "The walk off the plane."
Cons: "There was no obvious indication before booking these flights that I would need to pay for a bag. That should be in bold letters and flashing at the person buying the ticket. I was very mislead and plan to never use your air line again. Also, my chair area was not cleaned. There was used tissues and a barf bag in front of me the entire flight. I could have gotten sick because of your negligence."

Cons: "It was cancelled and I'm having trouble getting a refund."

Cons: "seated outside the rear toilet and it smelled like I was flying in an overstuffed Porta-Pottie for 4+ hours mon my ride home. Besides that there were very obnoxious kids seated right next to me and in front of me. On the flight to Chicago, there was a kid behind me who kept kicking me in the back all the way there."

Cons: "the flight attendant was much too talkative. She kept making comments and announcements over the loudspeaker to the point that I could barely read my book"

Cons: "Trash scattered around plane. Dirty seats. Loud attendant on the speaker that talked too much."

Cons: "that you had to pay for EVERY single thing you did with your airlines. you should tell people this upfront before they book a ticket with your company. I could have went with a different airlines for a ton less money after all the fee and charges you do. I will never fly again and I will also pass along to friends and family"

Pros: "The price of the flight, how easy it was to accommodate me for the cancellation of my flight. Good customer service"
Cons: "You have to pay to pick your seat, for a carry on (you are allowed to bring smaller luggages aboard). The gate agents don't have a good grasp of the lines and people around the gate. Seems more chaotic boarding than the other airlines"

Cons: "Spirit cancelled flight without any offers"
