("our" included 27 passengers flight to Bradly)"
Cons: "There are many opportunities for improvement with company. First there were no service employees around for ticket check in at 8pm so there was a huge line/crowd of people waiting for 2+ hours to simply check in tickets and bag drop.

Just wait at the 51B Is so hard to get some power to recharge all my gadget... Overall the staff are good... I'm so tired, i don't know are they give a food/no?"

Pros: "No nonsense just fly and get to your destination. Staff seamed competent from check in to unboarding."
Pros: "Assigned seats"
Cons: "Charges fir everything"
Cons: "My initial flight was delayed over an hour AFTER the plane was completely boarded. We were scheduled to depart at 9:20am and didn't depart until 10:45am. I understand that things happen, BUT I certainly wish this had been anticipated before the plane was boarded AND no one came on the intercom to let the passengers know what was going on until we had been sitting there for 45 minutes. THEN, while in flight, I expressed concern about making my connection. The flight attendant suggested that I would probably need to just "run" to make my connection. This was also disappointing. Can't there be a little communication between Frontier staff? OR could the flight attendant HELP usher me to the front so that I don't miss my connection rather than just suggesting over the intercom that other passengers let those with connections off first? Fortunately, some other passengers spoke up for me so that I could get off and "run," but this was overall stressful and disappointing. I prefer the experiences I've had flying OTHER low-cost airlines like Spirit and Allegiant. Frontier needs better communication."
Pros: "Very professional."
Cons: "That it had to end."
Cons: "My flight was delayed several hours and I would miss my second flight and be stuck in Denver over night. Frontier refused to accommodate me so I canceled the flight and booked with American Airlines. I am still waiting for a refund both from frontier and kayak for the fees bad."
Cons: "We got delayed for over 2 hours just siting on the tarmac, the crew didn't explain what was going on, they weren't very apologetic about how inconvenienced we all got and made no attempts to compensate or appease the entire flight. The wait for bags after we got back to Denver was horrendous. We all went to a different bag claim because we weren't told where to go at all and the signage and labeling was all wrong. I usually don't mind flying frontier but yesterday I was angry and disappointed at the service we received."
Cons: "I did not like the idea of refreshments being sold on board. Even if it means incorporating 3-5 dollars for refreshments. The bills will give better outlook. Moreover that can still be accommodated it the current bills"
Cons: "I was removed off the flight for another off duty crew member to have a seat."
Pros: "No lines at all very smooth :-)!"
Cons: "They're over charging $40.00 for a carry on bag thats way too much it sucks!! They don't even say anything about it until is time to precheck your bags!!!"
Cons: "They changed gates and there were no signs or announcements. We would have missed our flight if I hadn't searched out an airline employee and asked."
Pros: "The boarding was fast."
Cons: "The seats are not comfortable and do not recline, you have to pay for carry-on and drinks. No radio or complimentary snacks or drinks. This is completely no-frills. By the time I paid for a carry-on the ticket would've cost the same as a regular plane flight on United, Delta, or American. Not worth it for the overall discomfort."
Cons: "Check in counter crew were 45 minutes late for work."
Pros: "I got home safely"
Cons: "Almost getting hit by a metal box. I was sitting in the front row on the isle seat when one of the boxes containing the flight attendants safety demo items came flying at me along with a giant water bottle during take off. My arm was grazed and another person was hit on the leg. The fight attendants didn't offer an apology or explanation. They didn't secure the box or put away their personal bottle of water. I'm not usually anxious while flying but that did it."
Cons: "Seats are like cardboard. Had a delay on connecting flight and got stuck in Denver for 4.5 hours because the crew was scheduled to come in late. Poorly managed. Rude staff. Never again."
Cons: "I was not told until I was getting my boarding pass that there was a $40 charge to carry on my bag. The plane was dirty and the bathroom smelled horrible."
Cons: "Fly was late"
Cons: "I did not realize they charge extra money for a carry-on bag. At that point you have no choice to pay the money. That should be noted up front."
Pros: "I enjoyed no part of this flight, it was terrible."
Cons: "Seats were uncomfortable and didn't recline, no free drinks or snacks of any kind were offered, and the check baggage fee was $40."
Cons: "An hour on the runway before take off and an hour on the runway after landing."
Cons: "The check in counter did not open until late where a large number of customers including me had to wait for over an hour and a half to check bags in. The plane had to sit on the runway for over 20 minutes waiting......"
Cons: "The Cost to get soda and snack.We had to wait in the plane for at least a half after the plane had landed before being allowed to pull into a gate."
Cons: "The ticket price doesn't indicate the real total cost. Every extra service or amenity is an extra charge. Everything! Check-in bags, carry-on bags, “ticket processing”. They even tried to charge a $522 dollar “name chage fee" when they made a mistake on my personal info. It's border-line false advertising. Very disappointed"
Cons: "The checkin staff were absolutely horrible and delayed me until my bag was about to be pushed off until the next day's flight. They charged me $35 for my second bag when it should have been $30. They scam and steal your money."
Cons: "Round trip fare was $178 - but $104 "additional fees" for seat (????) and baggage. I know it was in the details when I booked, so I paid, but I won't fly Frontier again because I'd rather just pay for the full amount at once. Silly process - feels like bait and switch and takes more of my time paying 3 separate times. It was a short flight, but to not even get free water or usb plug in is sub standard."
Cons: "They get you with all the add-on fees. And the base fair isn't even cheap."
Pros: "Getting off"
Cons: "It sucked the bologna from peehole"
Cons: "Frontier has way too many fees, fees to check bags, carry on bags and to pick a seat. I would rather pay extra in the beginning to avoid the hassle of juggling all the fees while checking in. Also the staff at LAX was no where to be found during boarding. I needed to speak with somene regarding my flight and there was no one around to assist and that may have taken part in me missing my flight."
Pros: "Organized on boarding"
Pros: "I liked the convenience of hours flown during my travel time."
Cons: "I did not like the outdated seats which had no headphone adapter, no charger for phones,."
Pros: "The plane went to the right city."
Cons: "Got a middle seat both ways. Not very comfortable."
Cons: "Hours of delays in both directions"
Cons: "Smooth flight."
Cons: "Spacing in between seats Comfort of the seats"
Pros: "Great price for seat. Seating a bit harsh for the longer flight. Space and padding. I was made aware of all the baggage costs, no surprises. So I believe you are improving that issue."
Cons: "Everything. Never using them again"
Pros: "Sort of cheap"
Cons: "Cheap at every level. Makes you feel unsafe. Are they cutting on cheap pilots too?"
Cons: "Charged me 60 dollars per carry on so I had to leave one of bags in the airport. Didn't exactly advertise that to us because we would have changed or canceled my flight, which is another way of saying that Frontier mislead us into buying their flight. Never flying frontier again."
Pros: "The spirit employees were very helpful when I checked in"
Pros: "The crew"
Cons: "Everything else"
Cons: "Crew was noisy, kept talking all together ,4 of them, in the front of the of the plane, loudly, and gossiping about other employees, so it was impossible to sleep and they seemed unconcerned with the passengers."
Pros: "Didn’t eat, no entertainment offered."
Pros: "Plane was new and clean"
Cons: "20 min Delayed departure"
Cons: "I had a question about a carry on and could not get an answer online nor on the phone for an hour. Ended up leaving the carryon in the car in case I wouldn't have been able to carry it on. Couldn't afford the possible "no" and the time it would have taken to go back to the car."
Pros: "How fast everything was and great service."
Cons: "Not a goof service no professional"
Pros: "The people were really nice"
Cons: "Paying $52 for my one luggage"
Cons: "I wasn't flying to hawaii"

Pros: "I liked the stewardess coming back to denver she was nice and beautiful"

Pros: "It was great everything on time and the fare was not that expensive"
Pros: "I love the low fares. Expect no perks, and no freebies. I'm totally fine with that in exchange for the super low fares."
Pros: "Nice job"
Cons: "Did not receive application to get refund on flight, now after i called several times i am told that its too late to receive my refund. I couldn't fly due to medical issues and no one helped me resolve this issue or get some kind of credit so I could possibly try and schedule for another trip. I paid for insurance because I was afraid that with my health issues, I may need to cancel. No one helped me fix this and no one called me back to resolve it. I was transferred all over the place and was told to call multiple people to get the issue fixed, just to be told to call someone else. I am very mad about this situation and will not be booking through this site or with Spirit airlines"
Cons: "Service desk with attitude"
Pros: "Reaped off by agent. Sold other ticket and then tell me if want cancel. I. Two minutes like to charge me other 100.00. All unproficional and agley and rude counter included super visor. The just like reaped off Custmers."
Cons: "No service and charged me extra. They atrophying game to cheat people. No satisfaction at all. I got charged 140$ I had 40 minutes to get yo gate. They did not let me an sails on their ticket. The supervised was very unproficional and rude. Counter employee was rude and abusivs"
Pros: "Flight was late"
Pros: "I did like the price point of the tickets very little in delays and customer service was on point all the way around"

Pros: "Great boarding time! Fit my schedule perfectly!"
Cons: "Seats don't recline."
Pros: "It was on time and good leg room"
Cons: "No wifi"
Cons: "In the last 30 minutes of our flight we hit a HUGE patch of turbulence that dropped our plane a considerable amount of feet. It also rocked us all around and about and passengers were screaming because of the terrifying jolts and movements. After this very un-nerving turbulence had subsided Spirit airlines decided not to say one word to the passengers the rest of the flight. There was no voice at all that said, "well folks we apologize for not seeing that patch of turbulence," or "we apologize for how bumpy that was," or even a simple, "welcome to Denver" once we arrived. Spirit airlines did not take the simple steps in reassuring the customers that we were safe or taken care of and I was very uncomfortable being on board my flight. This flight has left a bad taste in my mouth and will choose to pay more next time for a SouthWest flight compared to a cheaper, sketchier, Spirit flight."
Pros: "Large comfortable seats, leg room and punctuality."
Cons: "Cabin crew guy. Unfriendly attitude, spoke so fast into microphone he was unintelligible."
Pros: "I appreciate the low cost airfare and don't mind the simplicity of the in-flight services."
Cons: "Baggage fair is absurd."
Cons: "Flight delay. No bathrooms. No entertainment. No room. No food."
Pros: "I used Kayak to find a good deal and unfortunately selected Spirit, not knowing much about the airline. I later had to deal with the stress of cramming all of my belongings into a backpack to avoid the exorbitant costs of checking in luggage. I also learned that the airline had a horrible reputation for being late, and lo and behold, on the day of the flight, we were informed that the flight was 1 1/2 hours late."
Cons: "READ ABOVE"
Cons: "Employees were rud flight dirty and seats beyond uncomfortable and price became more expensive than an american airline business class with so many extra charges"
Pros: "Needs more room. Packed like sardines"
Pros: "Good seat, enough room"
Cons: "Cost for food"
Cons: "The flight went from "delayed" to cancelled in an hour giving us no chance to get a reasonably priced later flight to arrive in LAX by 10:00 a:m the following morning. We ended up having to cancel our LA reservations, paid to overnight near Denver airport and paid over $700 per person for 2 tickets with another airline. No advance notice was given to us . Nor was a reason given . This seems almost illegal !!! We will never fly with Spirit airlines again."
Pros: "Crew were helpful"
Cons: "The uncomfortable seats, the fact you have to pay for your check in, they are always late. Never traveling with spirit ever"
Cons: "Flights delayed multiple times both ways."
Cons: "Overheard the pilot saying that the plane we were boarding was a "POS," and that he didn't feel confident in the repair that caused our flight to be delayed."
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."

Pros: "Not crashing"
Cons: "Late schedule, last bags, rude airport personnel"
Cons: "Flight was cancelled. Terrible experience. Horrible customer experience. Will never fly Spirit again."

Cons: "If they gave free glasses of water it would be nice"
Pros: "the service was wonderful, the l8nes wwnt by quickly"
Pros: "We didn't crash"
Cons: "Everything else"
Cons: "Nothing was complementary. Uncomfortable seats."
Cons: "No complaints"
Cons: "My bag was Lost on my connecting flight and did not make it to my destination. The customer service that I experienced with spirit and the baggage pick up in LAX was the worst I have ever encountered. I had to contact corporate in order to start seeing resolutions [words of the employees]"
