Cancelled the flight. Too few employees to get us booked on new flights for a couple hours. Missed my friends' wedding. I'll never fly on Spirit again. They actually put me on a flight with American Airlines, so they did me the service of never having to fly Spirit again.

Great price for a nonstop cross country flight. Arrived on time with no drama, except for the seat neighbor who couldn't keep her feet out of my area.

Would've welcomed a snack, but hey...can't be choosy.

Was upgraded to premium economy in order to accommodate a family that wanted to be seated together. Never been upgraded in my life. The seat was very comfortable and legroom excellent. I was exhausted from a long weekend and not feeling well but managed to sleep almost the entire four hours without being bothered. The flight attendants left me a snack in my seat pocket which was very much appreciated. Almost wish I hadn't slept so much of the flight so I could've witnessed other amenities and service of flight attendants.

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.

The fares displayed include all taxes and fees for economy class travel and were found by the provider in the last 72 hours. Seats are limited and may not be available on all flights and days. Fares are subject to change and may not be available on all flights or dates of travel. Some carriers charge additional fees for extra checked bags. Please check the carriers' sites.
