Pros: The flight was fine and the crew were nice.

Cons: Gate agent was too much. A family had not been required to pay for carry ons on their outbound trip but she required them to pay $250. English was not their primary language. The mother apparently swore in Spanish- agent threatened to call police. Disagreed with FA, kicked off family.

Pros: The staff was excellent and the boarding process was quick and smooth. While the flight was delayed, staff really did a great job moving everyone along quickly and safely.

Cons: This was my first time flying Frontier. The flight was 2 and 1/2 hours delayed. While the boarding process was quick, the delay really put a damper on the flight. Seats were very uncomfortabe and seemed smaller than other airlines I have traveled more frequently. The carpet had gum all over it.

Okay 4.8

Pros: The crew was nice and boarding was easy. The plane was on-time. That was the only good things. Seats didn't recline and there was very little leg room.

Cons: Don't be fooled by the cheap price unless you plan to bring no luggage or pick your seat. After getting charged for each piece of luggage plus carry on and choosing our seat the price was much higher than it would have cost had we gone with another airline that included these items. Disappointing.

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.
