Absolutely nothing

From the moment I checked in the limit for bags was 40 I s not 50 I s. The bag price to check one normal was 50$ plus 30$ if it was under 50 not 40. The customer service could not have been more rude the flight was delayed 6 hours for “crew “ reasons. We were given only $7 to use and. Or bing eas openfor food. Awful experience never want to fly again.

Spirit doesn’t have screens at the airport to tell you which gate they are flying out of - must cost too much - only American airlines has them and i thought they were for the whole airport - how can you tell? so i went to the gate that said san diego - the only one. waited in line. find out as near the last one to board that i was at the wrong gate.

had to run to my flight leaving at the same time about 10 minutes away in an by running. Didn’t make it and Spirit only flies to San Diego once a day. So i miss Thanksgiving dinner with my family. So i have to go back to my apartment, an hour by subway, and come back tomorrow. First and last time flying with Spirit.

Zero leg room. Zero arm room. The entertainment system did not function. No food for such a long flight unless you pay more then the food is actually worth.

Flight crew was good, we arrived early on flight out and back! Feel like seats are tinier than ever, maybe it was just me. Food (water & pretzels) were OK, but nothing special (then again it was a short flight, so I didn't expect anything). Plane was small so we needed to gate check bags and the gate attendant came around and tagged everyone's bag for us, well before boarding which was hugely efficient - kudos to her on that!

Gate attendant's mic was broken (or she didn't know how to use) so she had to yell into the boarding area.

The flight attendant named Steven went so far beyond the call. He was attentive, he fixed our video system when no one else could and when he learned we were celebrating an anniversary he brought us a present. He was awesome!

Entertainment and crew were great- comfortable seats, got to watch a couple of movies with headphones provided by Delta; forgot mine so I assumed I would be miserable thru the whole 4 hour flight. so glad I was wrong! Would definitely take another flight with Delta... looking into the frequent flyer program as we speak

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.
