Cons: We missed this flight because our earlier flight was delayed and all frontier would do is tell us that we could “google” flights on other airlines to get us where we needed to go. No hotel voucher for the forced overnight, no refund for the missed leg, nothing. I really don’t understand how this company is in business.

Pros: The clerk was accommodating enough to look up other airlines where I could purchase another ticket. She also told me to never trust the alerts or website and to show up on scheduled time. I wish I had known this an hour earlier and $400 later. Thanks Frontier!

Cons: Got alerts from Frontier and checked their website and both said that the flight had been delayed an hour and a half. I showed up an hour before the delayed departure time and the clerk told me that the plane was loading and I would not be able to board. I understand I should have showed up earlier but my rating is based on the dishonesty of the time I was given.

Mediocre 2.0

Pros: The clerk was accommodating enough to look up other airlines where I could purchase another ticket. She also told me to never trust the alerts or website and to show up on scheduled time. I wish I had known this an hour earlier and $400 later. Thanks Frontier!

Cons: Got alerts from Frontier and checked their website and both said that the flight had been delayed an hour and a half. I showed up an hour before the delayed departure time and the clerk told me that the plane was loading and I would not be able to board. I understand I should have showed up earlier but my rating is based on the dishonesty of the time I was given.

Cons: The crew was rude to the passengers. They charge form 9$ to 40$ for seat selection. Charge for a Carry on bag (anything that doesn't fit under your seat). The flights had maintenance issue, hence delayed. I will absolutely avoid traveling with frontier in the future.

Mediocre 3.0

Pros: Not to much

Cons: Was like riding a city bus. Even in row one didn't have much room to stretch out. Check in took awhile. Only thing they had going for them was good pilots and staff. But the planes are trash no entertainment, little selection of food and drinks. Don't suggest at all.

Cons: We missed this flight because our earlier flight was delayed and all frontier would do is tell us that we could “google” flights on other airlines to get us where we needed to go. No hotel voucher for the forced overnight, no refund for the missed leg, nothing. I really don’t understand how this company is in business.

Cons: Website would not let me check in the day before or the morning or my flight. There was an error every time and I almost got to the end once. I could not change the time of my transportation and arrived 10 minutes past the check in deadline (an hour prior to the flight taking off). I was refused access to the flight and offered a flight 5 hours later. The staff was rude and not helpful. I had heard negative things about Frontier and now I know why.

Okay 4.3

Cons: Everything. The flights are constantly being delayed. Poor selection of snacks and beverages. If people are going to pay $3 for a can of orange juice. It should be a lot better than concentrate minute maid. There are no business class seats. None of the seats recline on the whole plane. Im still waiting for a voucher from a previously canceled flight.

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.
