Staff is rude and incompetent, they way over charged my account for for services that weren’t even available but wasn’t told this until after they charged my card. Seriously considering taking my experience with them to local news outlets so this doesn’t happen to anyone else !!

BESIDES BEING IN ZONE 1 & HAVING A WINDOW SEAT? NOTHING. It probably happened by accident, because I booked the Shy before and that's all that was probably left.

Just build carry on to your flight fees. Making it an option is inconvenient. Besides business class who travels with just a personal bag? SERIOUSLY?

Tried to change flights because of my mother's passing and had so much frustration to change the flight it became too much to deal with. I will be happier to pay more for a different carrier in the future than fly on Frontier.

The screen at the also gate did not reflect this was headed to Orlando or that it was a frontier flight causing unnecessary confusion. Unsure why no signage was used.

Trip was cheap and the flight was great

I didn't like I had to fly night time flights both times and that my seats changed unannounced to me for my first flight resulting in extra charges.

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.
