Crew was amiable.

Fees for carry on were hidden and expensive. Boarding called groups 1&2 immediately, the. 3&4 within 30 seconds. This was due to plane being delayed. In either case the boarding turned into a zoo.

The crew had a great attitude and was able to make us laugh despite the fact that we were leaving late.

The plane was dirty- there was balled up gum wrappers, food wrappers, and bites of food on the airplane floor. To make maters worse the carpet was already stained in multiple spots. My tray table also was dirty with sticky soda that had spilled on a prior flight. I was quite disgusted by the condition of the plane.

Okay 4.0

The flight attendant who presented the pre-flight info was snarky, made inappropriate remarks that she thought were funny and was unprofessional. This totally undermined my confidence in the crew. I think they should present that they take our safely seriously. I am unlikely to use this airline again.

Flight was on-time, into a lightly traveled airport. I sat in the back and had the row to myself. Most Frontier seats do not recline and this is a blessing as on other airlines someone usually ams their seat back into my knees.

If you're going to charge for everything (including water) at least make the food selection interesting.

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.

The fares displayed include all taxes and fees for economy class travel and were found by the provider in the last 72 hours. Seats are limited and may not be available on all flights and days. Fares are subject to change and may not be available on all flights or dates of travel. Some carriers charge additional fees for extra checked bags. Please check the carriers' sites.
