The bathrooms were disgusting. I understand that the flight crew can only do so much, but they didn't do anything after they were told more than once that the bathrooms were gross. They just gossiped with one another. Also, I am a teacher abroad and have been to many countries in many flights, but this is the first time I have ever been sick in a flight. My head is throbbing from the change of pressure and in all of my years of flying, I have never felt like this. it was a poor experience, and I will be grateful when I don't have to fly with Spirit airlines in the future.

Everything was good. The stewardesses were really nice. I didn't try the food or entertainment, but I'm sure they were good. They let me sit in an exit row for free, which is nice because I'm tall.

The flight was delayed a couple of hours.

It got me there alive. They gave me a full can of soda.

It was inexplicably late (no reason given nor obvious weather concerns). Staff varied between disinterested to unpleasant throughout the trip. Had to check my carryon at the gate despite the fact it fit in size regulations (was threatened it would be put on the next flight if I didn't). They allowed group 3 to board way before everyone in group 2 had gotten through. Power outlets in concourse K at ORD are a joke. I could go on and on.

Plane was available waiting at airport, weather was ok... switched gates -made only one announcement,had people line up at new gate, then switched gates again had people lineup for boarding,then announced flight will be delayed 1.5 hours - though plane was at gate. Meanwhile about 11 Spirit staff were running around giving conflicting info- Totally a disorganized operation at Chicago O'Hara Spirit crew- and bad communication with passengers. I flew 4 flights in two weeks the crew in O'Hara were totally spaced out. Most likely will select another airline for future travel.

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.
