I want to clarify that I boough tiquests with Lufthansa not with United... and I had to travel United most of the time to Africa and Bach to the USA... united socks terrible ... bad food and old plain to cross the Atlantic... besides the service and the bad actitude of the employees... when I travel international I want only Lufthansa. So, kayak you tricked me ....horribly!

Fast boarding and that's the only good quality. No refreshments or snacks offered without a price tag included. Seats don't recline. Uncomfortable hard seats without any head rests for Support. Small tray tables that won't hold a laptop or drink.

It's been 45+ minutes after landing that we have been stuck on the runway unable to dock the plane due to some delays. How Terrible is it that the pilot gets on the radio to say he has no updates or much information to give! People are antsy, children crying and this delays all passengers with other accommodations. Seems like there's no communication or organization from Frontier at all!!'

What I liked? That the flight ended and I could get off the plane.

They charged to pick seats. They charged to carry on a bag. They charged for any drinks. The seats had NO padding. The seats didn't recline. The gate at O'Hare was dark and dirty. The travelers in my flight would have scared the residents of Mos Eisley.

Everything. The staff kept lying about the fueling issue. They kept blaming the fuel tankers being frozen. They said 3 of them came, however i sat on the window seat and only one tanker came. After being delayed for 2 hrs and 15 minutes, when we got to cruise altitude they asked us for money for water. Are you serious? Also i was told that same plane will depart from Denver to Phoenix. I was told the same thing while in Chicago, during the flight to Denver and in Denver. It turns out everyone knew the flight left already from Denver to Phoenix. Needless to say, I won’t be flying with frontier ever again.

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,
