The main crew person checking us in was very nice and attentive, tried to keep me posted on changes, and remained pleasant even though some were getting upset.

flight was delayed, staff didn't update us so people were getting upset and irritable while waiting to hear. Then flight times changed without announcements, upsetting some.

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.

Everything. The staff kept lying about the fueling issue. They kept blaming the fuel tankers being frozen. They said 3 of them came, however i sat on the window seat and only one tanker came. After being delayed for 2 hrs and 15 minutes, when we got to cruise altitude they asked us for money for water. Are you serious? Also i was told that same plane will depart from Denver to Phoenix. I was told the same thing while in Chicago, during the flight to Denver and in Denver. It turns out everyone knew the flight left already from Denver to Phoenix. Needless to say, I won’t be flying with frontier ever again.

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.

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..

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.

If you have more questions or if you have a bad price to report to us,
