Cons: "Basic Economy options for carry-on confusing/not clear. Surprise charge of $110.00 once we got to the airport. Airline specified on website that a full sized carry on was not allowed. We were under the impression that meant a personal item (second personal item) was allowed as that is not a full sized carry-on. Confusing language! Airport personnel were entirely unforgiving. Basic Economy is a tactic to attract customer at low price but with substantially subpar options."

Pros: "On first and off first"
Cons: "For paying for a business ticket and to be offered a bag of potato chips is unacceptable though I did have a few alcohol drinks. Seats were also well worn."
Cons: "Seat was tight in the shoulders 3 wide for a grown man."
Pros: "out stewardess only had 7 people on the flight so she spend time taking care of us. I'm not sure how things will go as this was the maiden flight.. but getting into watertown from BWI in 5.25 hours was really nice!"
Cons: "overall price. the flights to ORD from BWI was a little high. Having this airline advertise outside so that I could have flown cheaper to ORD and known about this connecting flight."
Pros: "The crew in first class was amazing. Friendly and helpful."
Cons: "Vegetarian food on first."
Cons: "My name was on both reservations, i did not notice this until my wife and i tried to check in. They would not change the name on one of the tickets to my wife, Kathleen. So we had to cancel the entire reservation. I have trip insurance with Allianz, and am trying to get a refund for the tickets. If"
Cons: "Boarding could have been better. If you have 5 groups you should have 5 lines — not 2. Also the terminal in Holland was extraordinarily cold."
Pros: "The crew was very helpful and kind."
Cons: "The entertainment app did not allow me to watch any of the quality programming and my seat to Chicago was extremely cramped and did not recline."
Pros: "Everything was really smooth sailing."
Cons: "Everything was great! The Charleston airport is small yet very nice inside"
Pros: "The sleeper seats. Flight attendants"
Cons: "Temperature during the entire flight was too cold! Food was not great for a first class flight!"
Pros: "I got to where I wanted to go"
Cons: "I reached out to your customer support already about this, but haven't heard back. The departure time (for both legs of my trip) that was confirmed with my purchase from Kayak was incorrect and caused a major inconvenience. I'd very much like to receive a response. My email addres"
Cons: "The plane was delayed due to “maintenance” but no explanation was given as to why."
Pros: "Crew was very nice"
Cons: "Better off paying more upfront with any other airline. As tickets will end up being same by the time you finish paying for luggage and your seat. Not worth the hassle and discomfort"
Pros: "Smooth flight and pilot a spoke to us a couple times"
Cons: "Stewardess over intercom had poor diction."
Pros: "Good boarding process"
Cons: "A crew member had a very loud, extremely personal conversation for the entire duration of an early morning flight. She made eye contact so I knew she knew what she was doing"
Pros: "The crew was nice and they were apologetic. I know it wasn't their fault. They gave status updates every 15 minutes but in the end they were generally 'wrong'. Some people were angry about this but it wasn't their fault. How could it be? They were just repeating what they were told. It's not their fault that their organizers told them incorrect stuff. I sympathized with them more than I usually would because some passengers were such jerks to them. I appreciate that they were keeping us in the loop. We basically knew as much as they knew. It made me feel like we were all in this bad situation together, which we were. They wanted to get home, too. That was the right way to handle this. The actual flight was uneventful. Plane was clean. Seats were about as comfortable as you would expect for the price."
Cons: "Where to begin. It was delayed 1.5 hours, then we boarded, waited maybe 30 minutes, then we UNBOARDED because they needed a new plane, then it was delayed AGAIN. When we finally landed in Chicago we were about 5 hours behind schedule. I feel bad for the crew because they were left dealing with angry passengers, I know it wasn't their fault. Just poor corporate planning. In addition I did have a truly mind boggling experience with an employee. We were lined up for our first boarding, in a huge line, having waited for 1.5 hours, and suddenly a woman with multiple bags cut in line. I said "Excuse me ma'am but there IS a line" and she smiled and said "Oh, sorry, I'm an employee". I apologized and she cut everyone and boarded. That's when I realized that she was NOT WORKING THE FLIGHT. She was just using her privilege to cut in line. She cut in front and saved maybe 5 minutes. I mean, why bother. Why bother pissing off paying customers to save 5 minutes. People around me were so angry. Then she got on the flight and held everything up because she needed to load her 4 pieces of luggage into the overhead bin, taking up an entire bin. Flight crew actually moved people's bags to accommodate her. And one of her bags was a full sized suitcase that would never have been allowed if she wasn't an employee. Simply ridiculous, the only thing saving her was that there were open seats. She was not taking a seat from a paying customer. I would say that I wouldn't fly Frontier again but honestly all of the companies suck so I don't know who to pick. Every airline has some story or another of crappy customer service. I wish the barrier for entry wasn't so high so that competitors could swoop in....as much as I dislike the Elon Musk's of the world it would be great if some billionaire swooped in with their money and made an airline that actually worked."
Pros: "on time and efficient"
Cons: "gave me seat in row 30 when other seats were empty"
Pros: "expeditious boarding, low fare"
Cons: "bad seats they do not recline of a 3-plus hour flight, no snacks or drinks without charges,"
Pros: "Friendly crew Fairly clean air craft"
Cons: "Seats don't boot recline There is not even one complementary drink during duration of a flight"
Pros: "Lower cost, but sacrifice comfort and amenities, flight attendants fine"
Cons: "Sat in row 26, nothing except bare bones service"
Pros: "The crew on the plane was sooo nice. The pilot was great. Super good hospitality."
Pros: "The price"
Cons: "I went to check in and the kiosk wasn’t working for anyone!! But they wouldn’t let you get agent assistance without going to the kiosk first. There were only 2 agents working behind the counter, and 3 walking around. The 3 walking around wouldn’t answer any questions. I was supposed to be tsa-pre check. it said it in the system but wouldn’t print on my ticket. She didn’t try very hard and told me to just explain it to the tsa agent. Riiiight, like they would believe me! They didn’t. The crew on the plane were fine. The seats are horribly uncomfortable, but again you get what you pay for."
Pros: "Attendants were pleasant"
Cons: "I had no idea the seats were going to be so small and close together."
Pros: "The male flight attendant was a lot of fun. He made us all laugh and helped to lighten up the experience."
Cons: "Late start with boarding."
Cons: "The crew handed out cookies and water. They should have offered softdrinks."
Pros: "That we took off and landed."
Cons: "I had to pay $58 for a CARRY-ON bag and then join the "$9 Club" to then spend something like $49 for the same bag to come home. The flight attendant laughingly said "The only two things that are free on this flight are the bathroom and the trash collection." On my flight back from Chicago, I ordered a double, neat Buffalo Trace to celebrate the fact that I'll never fly Spirit again. At least they have their humor showing right in their slogan: "Less money. More go." Yep, less money for me, and now much less go."
Cons: "Way too much time between flights. Too many extra costs."
Pros: "Great price!"
Cons: "A bit nickel and dimed for carry on and checked bags. Travel light for maximum savings on Spirit!"
Pros: "About the only thing that I can say I liked is, the boarding process went smothly for me & my luggage was on time."
Cons: "Where to start... paid more in bag fees & to get an isle seat for each(4)flights than I did for damn plane ticket! Flights delayed 4hrs another flight in same trip delayed 2 hours. Staff wasn't interactive/friendly I'd say 6/10 were nice. Asked for an isle seat the person helping at counter, said I'd have to pay to upgrade. Seriously- upgrade for isle seat!! I paid to have an isle seat on all 4 flights(I'm a disabled vet who was injured in the line of duty) I need easy access to toilets I'm unable to crawl over people, in turn need idle seat). Paid for isle seat all 4 flights- just to see the flights were super empty, people were sitting where they wanted anyway. Thanks for taking my $ for the seats tho spirit:-|. Staff wasn't that friendly compared to other airlines I've flown on. Not food. No entertainment on flight. Not worth it. If they don't do better business they won't last long I feel. There is potential just needs some work!"
Pros: "Nothing."
Cons: "Rip off airline...not worth the cheap price to then pay $55 for a carry on bag...plus you have to pay for drinks on the plane."
