In my own ignorance I booked with Frontier, believing that I was getting a good deal, so I suppose it was my own fault for the experience I had. $40 each way for carry-ons, $2.99 for a can of sprite, and being packed into seats like sardines really made me rethink ever flying with Frontier again.

The flight attendants we're very friendly. They actually took a lot of abuse from a few not so nice people.

I paid extra to be able to pick a seat. When I checked in, they had moved me. What did I pay for? Also you have to pay extra for things that I think should be standard. Such as reclining seats and enough space to open your laptop.

The flight was fine - it was on schedule and smooth. It's Frontier so there is no entertainment or food.

The flight was delayed for 2 hours without an explanation. On top of the delayed flight they changed the gate from one frontier flight to the next. The seats were uncomfortable, there were no complementary snacks or beverages. The food tray was smaller than the ordinary tablet device. And to top of the entire trip, the airline lost my baggage. I was informed that it may be due to the lack of flights they had coming out of my departure city and that it "should come the next day".

Travel process was smooth

During online check in I was charged for a bag I did not need. I called and was placed on hold for over an hour. Then the operator told me my bag fee was nonrefundable though I hadn't wanted to purchase a bag in the first place! I ended up checking a nearly empty bag for $40. Ridiculous. Horrible phone customer service. Will never fly Frontier again. Ends up being more expensive.

No where in my confirmation emails from kayak or frontier was there mention that 45 minutes before boarding I forfeit my ticket if I didn't already check in. I had no luggage to check and the line to security was non existent, but frontier had no one at their check ins and the auto check ins wouldn't print my boarding pass. I would have absolutely made my flight with ease, but no one answered the 800 number and no one around or that could be called could help me print my boarding pass. For 45 minutes I asked anyone and everyone I could for help. Not only did I miss my best friend' father's funeral, but frontier will not contact me back to refund the ticket that I paid for but was not permitted to use. NEVER fly with them, it's worth the extra money to fly with someone half respectable

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.
