I did not like the fact that I was charged $45 for a carry on piece of luggage both ways. It added $90 to the cost of my trip.

Mediocre 3.3

Baggage fees... oh and every flight was late and if they couldn't fill a plane, they would push people back to the next one to combine the loads and have the nerve to say it's a delay caused by TSA. My return flight home was delayed almost 3 hours, I missed my layover and there were no other flights out to my destination til the next day. I was a full day late and missed a very important interview thanks to Frontiers poor ethics.

Nice flight with competent crew.

Kiosks did not work for check-in so I had to queue up and wait for help. Then I got charged $45 for a carry-on. Not a great start to the day.

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.
