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 !!

Price was low for a last minute necessary trip

By the time you add bags, etc you are right around the price of a typical ticket without any of the extras we still get to enjoy, such as wifi, complimentary items, or comfortable seats. Baggage is always late as are the flights.

Boarding was good

How do you board a multi-million dollar aircraft, yet still find yourself in an old western tv show. Easy, fly Frontier Airlines. The seats were like riding on an old horse buggy. Hard and unforgiving. The only positive was I didn’t get any slivers in my butt. No complimentary anything. Even the old settlers from the past could rustle up something simple to eat and drink, but not on Frontier. They need to get up to speed in this department, other airlines are starting to give drinks and snacks again for the long wagon ride in front of them.

I liked the cheap fare, but it was misleading because once you pay for your seat, bags and water, its just as much as a regular price.

Nickel and dimed for everything. Minimum $5-$25 for a seat, $45 for checked bag, $40 for carry on, $3 coffee, no beverage service. And the plame was filthy to boot. So gross, never again.

The fares are great. And the flight was on time which is the most important thing. Boarding was organized

The seats are very uncomfortable and don’t recline . That could certainly be improved

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,
