Pros: Being one of the first on and first off the plane and in Row 1

Cons: I didn’t like the fact that the extra legroom I paid extra for wasn’t really that much more than a regular seat. Also, being in row 1, there isn’t anywhere to stow my personal item. It then becomes a carry-on because I had to stow it.

Pros: Being on time at departure and arrival is a challenge, but despite having a completely filled cabin, they made it look easy.

Cons: I boarded in Group 4 and all bins were full. So my carry on case had to be checked (several others’ cases as well). This caused me a 30 minute delay at baggage claim and some minor scuffs on an item that wasn’t designed for checking in. These are 2 reasons why I no longer check in. 3 is lost items.

Pros: I’m pretty positive everything would’ve been great however we called frontier Airline several times to tell them the connecting flight was delayed unfortunately making us eight minutes late and they departed without us so we were not able to be on the flight and now we contacted the office.

Cons: In this uncontrollable circumstances with proof possibly allow a credit or refund better because now we have to book another flight or make a red another arrangements to drive or salon and pay for rooms. Town that we flew out from did not have frontier. This is a family medical ER trip not pleasure

When I went to the airport to check in, 5$3 man at the counter said he was off shift and just walked away with no one to release him. It took us 15 minutes to get checked it. There are also NO barf bags anywhere to be found on flight. It was awful. Our flight arrived AN HOUR early and it was extremely turbulent and I barfed so much. It was disgusting. & will never take Frontier again.

Cons: Everything. I hate Frontier. They are the dumpsters of airlines. 8 would rather pay $100-500 extra to fly ANY OTHER airline.

Pros: Simple, straightforward

Cons: I didn't like being charged $40 for a carry on bag. I didn't like the uncomfortable seating for a red eye flight. Most people sleep on those and need some comfort. I didn't like having to pay for drinks and snacks. Yes frontier is a little cheaper but after figuring in what I spend on carry on bags and drinks and snacks, I should of paid for a different airline with more amenities and comfort.

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.
