The staff on the flight was awesome, very helpful and kind to my friend who is terrified to fly. We were even ahead of schedule.

To pay for a carry on item is just crazy to me... not to mention you have to pay for beverages and snacks. All you are given is water.

Website would not let me check in the day before or the morning or my flight. There was an error every time and I almost got to the end once. I could not change the time of my transportation and arrived 10 minutes past the check in deadline (an hour prior to the flight taking off). I was refused access to the flight and offered a flight 5 hours later. The staff was rude and not helpful. I had heard negative things about Frontier and now I know why.

The plane took off over an hr late due to lack of heat and the pilot had to reboot the system, once the plane finally took off the flught attendsnts then explained they would start the beverage service but were iut of most options and we could get ready to pay for what was left, maybe if they offered complimentary beverages at that point would've been a nice touch.

There's no "complimentary" snacks on Frontier. Which is fine, their flights are cheap and comfortable and the snacks are affordable. I also don't really appreciate having to pay for a carry on. I knew about this so made sure my bag would be considered a personal item, but I just don't know how I feel about that as a backpack may not even fit under that seat. But again, the flight was cheap. So, I don't know.

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.
