Cons: "Children (3 within the age of 8-12)unattended left to pull on and kick the seat in front of them, loud arguing that was never addressed. My hair was pulled several times when they would grab the top of the seat to stand up or just harassing each other. I also witnessed them on cell phones that were not in airplane mode and never once did their parent reprimand them for their behavior. I had to do this from the seat in front of them. When the flight landed the entire family talked loudly about pushing their way off the plane to get to another flight, little did they know others had connecting flights to reach as well. Poor behavior & left to make others have a worse flight"

Cons: "See above"

Cons: "The baggage fee for carry on baggae is very high."

Pros: "No entertainment on the flight and we didn't have any food. Flight was a direct flight. Everything went smoothly. Actually arrived a little earlier than scheduled. Didn't have to wait too long for our luggage."

Cons: "First flight was delayed to wait for connecting passengers, connecting flight was not. Had to leave the terminal and wait in line with people checking bags to get another flight which made me I miss multiple alternative flights I could have caught if they had a desk inside the terminal. What was left was an 11 hour set of connecting flights the next morning instead of the original 4 hour direct flight. Speaking with the person rescheduling me, she admitted that no one had informed them that our flight was running late, which could have been to blame for why the connecting flight was not held a few minutes. Icing on the cake: my missed connecting flight landed 30 minutes early."

Pros: "The crew were very polite"
Cons: "The hidden expenses and fees. The small useless tray tables and arm rests. The narrow seats and non movable seat backs."

Pros: "Overall experience was excellent."

Cons: "never saw that flight, it was delayed due to severe weather and we were still in baltimore. see above!!!"

Cons: "My seat mate described the experience as "The Flintstone Airline" and I have to agree. Most uncomfortable seats of any airline."

Pros: "Flight attendants were all super nice. Very friendly and caring. My first time taking plane with Spirit. Loved it!"
Cons: "There is no actually good meal so I had to take it with me. I'm pregnant so I need lots of good snacks and a lot of water too. So I just took with me to take care of myself. Will food and drinks you need to stay healthy includes in one carry on baggage? Cause if so, I had problem with it. :("

Pros: "Low cost"
Cons: "Carry on fee way too much $$"

Pros: "Long Hold times to reach customer service"
Cons: "Long Hold times to reach customer service Uncomfortable Seats didn't recline , not much space . Additional Charge for everything"

Pros: "The airplane was clean and new. Didn't buy food. Nice attendants."

Pros: "The staff was friendly enough & the boarding was simple."
Cons: "Printing the boarding pass was SUPER confusing, the ala carte pricing is SUPER annoying. Give the guy a free cup of coffee."

Pros: "The price was all right. I did, however, later (2 days) find a better price with another airline..."
Cons: "I do not like the carry-on luggage policy. Even with the change in the "carry on" size, I was still "hit up" for another luggage fee; which the amount is robbery for such a small bag. Also, the seating space is just too darn small. I'm an average size woman and I felt squeezed and restricted in my seat."

Pros: "nothing"
Cons: "They delayed the flight on purpose such that they would not have to rebook on other airlines. As soon as the last flight to the destination left on another airline, they cancelled the flight and refused to rebook on any other airline. I got rebooked 2 days later. The cancellation was due to a lack of a crew."

Pros: "Nothing"

Pros: "Left on time"
Cons: "Read the fine print. I guess it's a better deal if you don't have any bags (check in or carry on) and don't frills like water. Crappy gates, baggage service, check in, etc."

Pros: "The only redeeming thing about our trip was that it was a nonstop flight."
Cons: "Ridiculously tight seating. Even water costs extra. We'll never use Spirit Airlines again."

Cons: "I charging outlets, chairs are highly uncomfortable, staff was rude. They were more worried about the off dutie pilots than anything. I won't be flying spirit ever again."

Pros: "You get what you pay for...and with Spirit you have to pay for everything - even water or a carry-on or help from the agent when checking in. So much for "affordable" flying. On top of that, their planes are uncomfortable, with no power for devices and no internet. No thanks."

Cons: "Baggage claim seemed extremely long to receive our baggage"

Pros: "Low fare"
Cons: "Departure and return flights were both delayed. Baggage fees are excessive.Not sure the low fees are worth it."

Pros: "Nothing"
Cons: "Every thing"

Pros: "Direct flight"
Cons: "Lack of customer service and attempt to charge for every little thing possible."

Pros: "Better leg room, departure and arrival faster than expected which was awesome!"

Pros: "Nothing"
Cons: "My flight got cancelled and had to go with another airline."

Pros: "Nothing bad service all the way"
Cons: "Miss info paying for my bag 55 $ 18 $extra for my seat"

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. The lady a the boarding brigde wanted a 100 dollars just becuase we had 1 hand bag. Pure cheating."
