Horrible customer service. They rescheduled the flight 6 times. they kept lying on the status. Finally departed at 3 AM (instead of 7 PM). Totally arrogant behavior by their ground staff. They have food coupons that no one accepted in the airport.

I will not fly the airline again due to the cheap quality seats, discomfort and lack of any entertainment. not to mention all the additional costs/fees they have separated from the cost of the flight.

I didnt like the $50 charge for each suitcase. I didnt like that they charged $3 for a snack and another $3 for a soda! The 45 minute wait to get our suitcases was crazy.

Price was nice. I am quite tall so I also paid to upgrade my seat so the extra leg room was great.

The website, app, and customer service from their 800 number is absolutely terrible. I don’t know if I’ll fly Spirit again due to the lack of user experience on their site/app and the difficulty I had trying to upgrade my seat both online and over the phone. Everything else was as expected- no frills. No food, drink, carryon, etc.. unless you pay for it.

JetBlue did a good job, as usual.

There was a screaming Infant in the seat next to me that continued to scream for the first hour and a half. I requested earplugs, and wore them under my 34 dB noise isolating earmuffs (which were made for use at a gun range). The screaming was still loud enough to give me the worst headache that I've had in 4 years. Once this baby stopped, the baby in the row behind me began to scream and the one across the isle from him/her joined in. I would happily rebook with JetBlue if there was an option to not be seated within 5 rows of a toddler.

The seats are comfortable. Enjoyed the TV. JetBlue is our preferred airline. Haven't had a bad experience.

The free snacks could be a lot healthier, i.e. apples, hummus,

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.
