Frontier had a very nice/helpful/empowered young woman working at the check-in counter at SLC and later at the gate.

Frontier has unclear fees, so be warned. Kiwi.com never offered me the option to purchase a bag; I had to go to Frontier's website to do that (confusing enough, but also, I shouldn't have to use two websites). However, to purchase a bag, I had to pay an $88 booking fee because Kiwi.com couldn't check me in. The nice young woman at Frontier check-in counter in SLC took mercy on me and only charged me $45 for my bag instead of $60. Their customer service was chat-based and VERY slow (not to mention they had no way to actually help me). I contacted them twice; once to cancel the flight (they charged a $20 fee to do so, which I thought was illegal within 24 hours) and once to deal with the bag fee issue. I would NEVER use kiwi.com again.

Price was great. Flight was great from take off to landing, luggage arrived in reasonable time upon landing.

Technical problem with Kiwi, so had to go to Frontier website and print my own boarding tickets. Not a big deal, didn't have any problem doing so, not sure what Kiwi problem was. Plane seats are close together, lucky I am an average size person so didn't feel too crowded.

At some point my stroller was lost and never recovered - it's a $300 stroller and they are offering $75. Hopefully I can find a one-year old receipt somewhere and get a little more reimbursement :(

The planes did not crash.

Luggage charges more expensive than United. Very little room for carry-on bags. Only the seats in the first 3 rows reclined--and only slightly. No free beverages. I don't care about entertainment but my kids missed it.

Price was great. Flight was great from take off to landing, luggage arrived in reasonable time upon landing.

Technical problem with Kiwi, so had to go to Frontier website and print my own boarding tickets. Not a big deal, didn't have any problem doing so, not sure what Kiwi problem was. Plane seats are close together, lucky I am an average size person so didn't feel too crowded.

This plane was very nice - clean and comfy

At some point my stroller was lost and never recovered - it's a $300 stroller and they are offering $75. Hopefully I can find a one-year old receipt somewhere and get a little more reimbursement :(

Frontier had a very nice/helpful/empowered young woman working at the check-in counter at SLC and later at the gate.

Frontier has unclear fees, so be warned. Kiwi.com never offered me the option to purchase a bag; I had to go to Frontier's website to do that (confusing enough, but also, I shouldn't have to use two websites). However, to purchase a bag, I had to pay an $88 booking fee because Kiwi.com couldn't check me in. The nice young woman at Frontier check-in counter in SLC took mercy on me and only charged me $45 for my bag instead of $60. Their customer service was chat-based and VERY slow (not to mention they had no way to actually help me). I contacted them twice; once to cancel the flight (they charged a $20 fee to do so, which I thought was illegal within 24 hours) and once to deal with the bag fee issue. I would NEVER use kiwi.com again.

All of the extra fees. Absolutely ridiculous. It would have been less expensive to take another airline.

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.
