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.

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.

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?

We loved the flight! Everyone was super friendly and the plane was really clean.

The actual seats were super uncomfortable. Great leg room, but no cushion or comfortfor your back and bottom.

The crew was friendly.

The boarding policy changes are confusing. No longer boarding from the rear of the plane and no explanation of how to board sooner without buying an extra space seat. Also the seats are less comfortable.

I did like that "new plane" smell. Good pretzels.

Plane was too new; computer system hadn't been set right. Left 45 minutes late, though made up some lost time in the air. Very rude passengers (obviously not the airline's fault, I know). Everyone thinks they should be the first to get off the plane!

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.
