Sprit should not charge for carry on luggage. They should add that cost into the cost of the ticket and stop falsely advertising like they have cheap flights and they don’t. Also charging for snacks after people have had to pay high prices for luggage is highway robbery.

I would never fly spirit again because of the nickle and dime cost. We had to pay for each seat on each flight, baggage for each flight which came out to $160 for one bag round trip. Not to mention they charge you for basic food on the plane. Like are you kidding me. The fairs it self might be cheap but you will spend an arm and a leg to fly and check baggage.

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,
