Inspire of making it clear all through booking, check-in and seat assignment, I was assigned a seat in an emergency exit. I told crew before I boarded that I could not open the emergency exit at assigned seat, due to an injury. I had to board almost last waiting for them to find someone who would take that seat. Then they put me in a non-reclining seat. I was given the wrong free beverage and the crew never came back. So I had nothing to drink on a 4+ hour long flight.

First time flying with Spirit, only thing I did not care for was the prices for checked on luggage. $45 for carry on luggage and $40 for checked luggage? Although paying for this service gets you on the plane quicker

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.

Free movies on the plane, because of errors.

4 hour delays both ways. We missed our connection flight due to delays on the way home. That connection was the last flight out of that airport home. We ended up having to sleep in the airport overnight, because United wouldn't pay to put us in a hotel even though the delay was because of a mechanical error on the plane. Our 5 hour flight turned into a big ordeal.

Getting on the plane was quick and we took off on time. The plane was clean and the seats were as comfortable as i guess airplane seats can be.

I didn’t like the fact that they made me check my bags and then there was so much space on the plane where i could have placed my very small duffle. It was totally a waist of $50 and the attitude i received from the flight attendant wasn’t appreciated.

The crew was excellent, very friendly and helpful. the pilot announcements were unintelligible. I appreciated that the crew anticipated that overhead luggage space would run out and offered gate checking of luggage all the way through to my final destination. I took advantage of their offer and it made my connections so much quicker and smoother

The room for seating is way to crowded, I need more leg room and don't feel I should have to pay extra for a minimum requirement for air travel. Beverages were skimpy, should be offered more often.

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.

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.
