Mediocre 2.6

Pros: Started with the nickel and diming during check in. The app wouldn't take my card so I had get on the website. Apparently buying the ticket doesn't give you a seat, you have to pay extra for that. Taking more than a laptop bag or purse, that's extra. Right there, your low fare is shot to h#ll. Definitely check the hidden costs before booking. Then came a 5 hour delay of the flight, apparently the plane had mechanical issues at it's previous stop. Frontier provided $10 meal vouchers, which doesn't go far in an airport. Seats don't recline at all and you feel like you're in a cattle car. The seat back tray is about 6" and doesn't hold much. The combination of turbulence and a pilot yanking the plane around during landing brought out the air sick bags by several passengers around me. Then on the ground, he was racing around and taking turns like an Indy500 race car. I seriously thought he was going to do a handbrake turn into the parking spot. Frontier provided vouchers worth $100 per ticket for the flight, but only good for another Frontier flight. I don't think so...

Cons: Several hidden costs. Uncomfortable seats Rough landing

Then we're asked to clean our seats for next flight to save time for the crew to clean up. All the hidden costs, ridiculous! The seats uncomfortable.

Mediocre 2.6

Pros: Started with the nickel and diming during check in. The app wouldn't take my card so I had get on the website. Apparently buying the ticket doesn't give you a seat, you have to pay extra for that. Taking more than a laptop bag or purse, that's extra. Right there, your low fare is shot to h#ll. Definitely check the hidden costs before booking. Then came a 5 hour delay of the flight, apparently the plane had mechanical issues at it's previous stop. Frontier provided $10 meal vouchers, which doesn't go far in an airport. Seats don't recline at all and you feel like you're in a cattle car. The seat back tray is about 6" and doesn't hold much. The combination of turbulence and a pilot yanking the plane around during landing brought out the air sick bags by several passengers around me. Then on the ground, he was racing around and taking turns like an Indy500 race car. I seriously thought he was going to do a handbrake turn into the parking spot. Frontier provided vouchers worth $100 per ticket for the flight, but only good for another Frontier flight. I don't think so...

Cons: Several hidden costs. Uncomfortable seats Rough landing

Okay 4.0

Pros: The prices

Cons: Paying for a carry on Seats do not recline No complimentary beverages Flight was delayed and we rarely received updates I understand that you charge for everything in order to offer better prices, but by the time the customer pays to bring on luggage, we are paying the same price as an airline that allows baggage for free with inclusive drinks, snacks and seats that recline.

Good 6.6

Pros: Overall good flight.

Cons: I’m tall so comfort is not an option unless I want to pay for it. No food unless I want to pay for it. No entertainment unless I want to bring it.

Cons: Weather delays happen. But Frontier left me stranded in a Denver and offered me no options other than a refund? No rebooking no hotel nothing.

Prices are per person and are for e–tickets and include all taxes & fees in USD.

We attempt to get accurate prices, however, prices are not guaranteed.

Here's why:

We’re not the seller.
At KAYAK we don’t set the prices, so it’s not possible for us to guarantee what other companies are selling.

We compile tonnes of data for you
Our service lets you quickly and easily compare results from hundreds of travel sites at once. In this sense, KAYAK is a search engine and we can't guarantee prices we find.

Why aren’t prices accurate 100% of the time?
Prices on airline seats, hotel rooms and car rentals can change frequently. Several people may also be trying to buy the same travel option simultaneously. As a result, you may find, on occasion, that certain prices are no longer available.

If you have more questions or if you have a bad price to report to us,
please send us an and someone from our team will get back to you promptly.
