The fact the flight was only a bearable 2 hours

The ticket was $30, but then taxes and fees were $43. That's just the start of the money trap...to have a carry on- $60 To check your bag- $45 Then to "reserve your seat" it's any where from $14- $30. The seats didn't even recline. Then during the flight everything costs money, even WATER! I will never fly Frontier again unless I'm desperate...I mean, REALLY DESPERATE!

DID NOT like having to wait in Denver airport for the scheduled 9 hour layover and then delayed for another 1.5 hour for a total of 10+ hours. DID NOT like getting lured into a great schedule in March and then in May you cancelled the flight and we had a 9 + hour layover. TERRIBLE. Will never fly with Frontier again. :(

Cheap tickets

You must experience the rigid, non-reclining seats packed impossibly close together to get the full Frontier experience. Nonetheless they often have the cheapest airfare so what is a budget traveler to do?

I was supposed to be the volunteer for overbooking problem, but the ground attendent helped me by arranging a seat for me. If she didn't do that, I would miss my next international flight. I'd like to say thanks here!

Premium economy is a must for me from now on. I am 6'4" and the extra leg room makes all the difference in the world. My flight was at night so I had little interaction with the crew. Overall I had a very pleasant experience on united and would definitely fly with them again.

Food options were limited to snack boxes. I had a layover in Denver. At the time of my arrival all of the food options in the Denver airport were closed. I would have appreciated some more substantial food offerings on the plane, as I had to go without dinner thatnight.

New airbus has even LESS room!! Have to manhandle your personal bag out of the even smaller space under the seat! A soda is $3! There is Nothing to read anymore and the crew are overwhelmed with cranky people... making them cranky.

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.
