Good 7.0

The flight attendants were more friendly and down to earth than the staff of other airlines I've flown. The airline doesn't give out free snacks or beverages but at least the bag of Chex Mix I purchased was sizeable. Since I chose not to pay to pick my seat, a seat was selected for me at random and I ended up in row 5 without and y seat mates. This random seat assignment probably goes bad as many times as it ends up good so I wouldn't want to take my chances with it too often.

As a Colorado native, it's sad to see that Frontier has become a bare bones, pay extra for any and everything we can think of kind of airline. Charging $35-60 for carry/on luggage is RIDICULOUS. Why bother having a ticket class where nothing but a purse or briefcase can fly for free? Setting the prices to look low and then adding an additional $35-60 charge (depending on when/where one purchases their luggage allowance) is duplicitous and shady.

When 6:30 a.m. flight home was postponed until noon, we weren't able to make our connection and they didn't have another flight to get us home until the next day. Had to cancel and go with another airline.

The flight attendants and pilots were professional and there is not any complaint with them. Please see the other box to explain the reason for the crew to be rated poor.

When my flight landed in Denver at the end of my trip the crew under the plane unloading bags were having a shouting fight with extreme profanity being screamed at each other. From what could be understood there was one person shouting the loudest. It sounded like a bar fight and all the passengers on the plan heard it all. We were all waiting to get out of the plane and listened to the whole argument. Very unprofessional. It will cause me choose another airline next time I fly.

The plane was VERY uncomfortable, the flight was delayed because of a flat tire and a "brake problem" that wasn't communicated to the crew until we were all lined up in the gangway to board. Everyone was extremely uncomfortable on the flight due to the cheap seats. I wasn't aware that I would have to pay for my seat on top of everything else that we are nickel and dimed on. It was a horrible experience and I will never use Frontier again.

The seating is even tighter than normal coach, but my flight was only 2 hours so it was no big deal. I don't think I would take a longer flight with seating that tight.

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.
