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.

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 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!

For the first time I did not fly on a puddle jumper. Not only was it a real jet, it had good seat comfort and leg room even in economy class. The crew was friendly and attentive. They came by with offerings of water at least 4 times for a 2+ hour flight. Contrast that with my last two 5 hour flights on Virgin and American where they came by with water — ONCE. WiFi wasn’t working for either flight and of course the lack of decent food is discouraging. The coffee has improved which is a plus. Overall, good job, United! Nice not to be jammed in like sardines for once.

WiFi wasn’t working and food selection is non existent. Other than that, a very pleasant flight overall.

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.
