Scores according to KAYAK customer reviews
Pros: "It got the job done"
Cons: "We were delayed about 45 minutes, which happens, I’m fine with that. I did not like that there was zero communication about it. Up until the scheduled takeoff they still hadn’t told us it would be delayed and nothing else was updated either to indicated a delay."
Cons: "The way have to bus us to the plane."
Pros: "Plane interior was bright and new."
Cons: "Baggage retrieval. Chairs don't recline."
Pros: "This airline is completely disorganized and with no apologies. I waited an hour in a bag drop line and then an hour and a half in the plane with no real explanation as to why. Planes are super bare bones which is fine. They just seem to be incredibly understaffed and unorganized as a company. All of the attendants and desk workers were trying their best but were set up for failure"

All of the attendants and desk workers were trying their best but were set up for failure"
Cons: "layover nothing was in order staff sucked yall kept moving gate yall could at lest give us a soda for the long rides"
Cons: "It was a total shit-show. Only one person to check people in the counter. No kiosks were working on my way back. On the way there very few were working, I did it once, paid for my one bag, and it printed blank. There were no available workers to help me, so I switched to another kiosk and had to again, pay for my bag. On the way back we landed and had to wait 30 minutes to get to the gate. It was a horrible experience in all."
Pros: "Family emergency caused us to stay 4 more days -"
Cons: "No credit offered"
Cons: "The breaks failed on the plane so we had to deplane at the gate. They couldn't get us out until late the next day so I had to cancel my trip."
Pros: "Timely as expected"
Pros: "I sat in row 3 and had a lot of leg room. I am 6' 2" and usually have 0 leg room in most coach seating."
Cons: "There were no free snacks/soft drinks available."
Pros: "Reclining seat"
Cons: "Not having a seat in front to stretch legs out."
Cons: "No one at Frontier desk. Sign stated to check in at kiosk or online, but there were no kiosks. Online check in was unnecessarily long and onerous, and then last step couldn't be completed; advised to download app. Then had to repeat process with app. Then had to go back to desk to drop off luggage; still no one there, very long long formed, and finally when someone came to the desk the line took 20 minutes. Every other airline has figured out how to avoid this!"
Pros: "Cheap, kind of"
Cons: "No food, no water, no recline, no relax, no hospitality"

Cons: "Uncomfortable and everything was delayed. Overall terrible"
Cons: "We landed early and then had to sit on the tarmac for 45 minutes for a gate. And then the jetway didn't work. So instead of getting home early for a change, I wasn't home until very late."
Cons: "It is very clear that Frontier is a budget airline that prioritizes money over people. Right down to the unnecessary announcement that you may not drink your own 'minis' but are required to purchase their liquor (at ridiculously inflated prices). The pretty girls who approached us and offered perks...for a price as we queued for more than an hour simply to check in, made me feel even more like faceless animal prey with dollars in my pockets. I will not fly Frontier again, no matter how 'cheap' their tickets."
Pros: "I got home safely"
Cons: "Both flights were over an hour and a half late. The seat designer should be arrested! Drinks and snacks were beyond "overpriced"!!"

Pros: "Nothing in particular stood out"
Cons: "Cost of ~49 $ extra for a carry on. This adds 90$ to trip. I would have choose another airline if I had known this was the ask."
Cons: "The hour and a half delay. Some of the passengers who were drinking were a little noisy, and used language inappropriate for the kids and the location for adult"
Pros: "Delayed 2 hours with no update information. As a frustrated passenger asked for answers. Called all over the nation for help. Upon boarding, was told Frontier had the right not to serve me. Refunded my money and then i had to book through another airline at 3am... long story short, nightmare."
Cons: "All of it."
Cons: "Showed up a day late. Oops!!!"

Pros: "It was ontime and uneventful. OTOH it was Spirit."
Cons: "Cramped seating"
Cons: "So just remember that while the ticket itself might not be that expensive, you'll be charged for everything other than your personal bag, which might make up for the difference in ticket cost. Both of my flights were also delayed by about a half hour, which didn't make that much difference to my trip, but could be problematic if you have a tight layover."
Pros: "Nice to have an economic no frills option for flying. Would like them to allow a normal size carry on for free. It wouldn't be worth the price if I had to pay the large bag fees."

Pros: "Nothing much"
Cons: "Paying my small luggage for 45 dollars"
