I arrived at the airport two hours before my flight out of Denver. The Frontier counter had a line that wrapped out of the ticketing/check in area and out into the main part of the terminal. I ended up missing my flight because it took me over an hour to get checked in and to security. There were several other flights leaving at the same time where a large numbers of passengers were also going to miss their flights. I've never seen anything like it in all my years flying.

I was forced to pay for my carry-on which was the same price as the check in bag. The complimentary drink and nuts were a charge and I missed my layover flight because they did not announce it. I want my money back! I had to get a whole new ticket from a different airline.

Quick, easy boarding. Flight arrived, and left on time. Tickets were very affordable.

How can I rate a 10 dollar sandwhich with a tiny bag of chips any higher? Entertainment? Non existent.. Wifi didnt work. I made several calls ahead of time to check if i can carry alcohol in 50 mL labelled bottles, sealed. I was told yes. Asked if i could drink them on the plane. Yes. Then I was told AFTER on plane consumption of my own alcohol that this was a federal offense. Epic mess up you guys..

The crew was friendly. Ticket cost was appropriate.

Seats were HORRIBLY uncomfortable. I’m slender but tall and in my window seat my head hit the ceiling so I had to either slouch or turn my head to the side for the whole flight. In flight entertainment was awful (some weird sitcom loop) and the WiFi didn’t work with my phone nor laptop. Basically sat uncomfortably sideways with nothing to do for 2 hours. Flight also arrived late, causing transportation issues.

We got there safely.

They made the flight more than an hour late so that 12 people could make a connection. I understand having some compassion, but more than an hour? What about the rest of us who, do to the sardine can nature of plane travel these days, had to all listen to each other call their appointment s and explain the delay? Also, they charge for nearly everything -- soda, checked luggage ($45 for one!), carry on. I won't choose Frontier again unless it's my only choice.

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.
