Really nothing.

The additional cost to pick a seat, and luggage. I no longer considered it a good deal. Our layover was extended 2 hours in Denver no explanation was given. The staff never came out to let the waiting passengers know. I only found out because I went to the customer service counter. Waiting passengers were mad and it could have been prevented. No food or entertainment was provided only a glass of water was free. All snacks and beverages were additional cost. No entertainment was available not even at an addditional cost. I probally won't fly Frontier again.

In LAX the check desk was supposed to open at 7am, the came out about 20 minutes like and put no effort into urgency. On my flight from LA to Denver we left departed more than 20 minutes late and none of the flight attendants felt it was necessary to explain what was going on to the passengers. Probably one of the worst flying experiences I've had.

Flight wasn’t full

I had to re-purchase the same ticket I already bought because I missed another flight on the same itinerary, they cancelled this leg of the trip for me. Spirit will rush the planes out so they have a better on time percentage and regularly leave many passengers behind. Then you have to buy tickets again because it’s in their terms (and I believe other airlines terms too) that they cancel remaining legs if one is missed, and there’s nothing you can do about it

Overall I liked the price. Never had any problems with Feontier before so that is why I booked it.

Leaving Denver it was confusing when boarding because the boarding agent was talking on the loud speaker and was saying that it was going to be a fast turnaround and some other stuff but more like rambling something about we were going to be late to Dallas. We wound up being right on time when we landed in Dallas. Wasn't really sure the purpose of the confusion.

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.
