This is the worst airline I have ever travelled! Such rip off artists!! Not only do they find every opportunity to gouge you in price, but they are also over booked, delayed and vulturistic (yes, I'm so angry I made up a word) in their practices.  Upon check in, I was gouged $10 bc they don't have clear signage that states that check in is a TWO STEP PROCESS WHERE YOU MUST FIRST GO TO THE KISOK. You actually don't see the $10 indication until you are right in front of the teller. Then! It's too late, because you've already stood in line 40mins and are running late for your flight. Next, you discover that it will cost you $50 for a bag, whether you check it or carry it on with you! Since you must pay for everything that is not a purse or a laptop. When questioning these fees, you'll love the scathing yet lethargic response you get from the Spirit staff (however, I'm sure that they're so used to it that they just blank everyone out). Finally, the best part? Is a hr long delay for \"scheduled maintenance\" - please tell me, if it was scheduled, why do we need a delay? And yet, we're still not going anywhere. As I submit this review, we have another 45 minute delay to cool off the plane. And, the one that made the announcement? He sounded as if this could end up being a longer delay. I may never make it back to Chicago & that poor kid making the announcements may end up hung by his toenails in the bathroom by an angry mob. Spirit? You Suck.
