Not cheap at all, they charge $150 for a cancellation made less than 7 hours, i cancelled because they want to charge for baggage $45 plus $40 carry on, plus water in the fly on Spirit. I decide to pay the $150 cancellation fee to avoid flying on that company, then next day i check my bank account and the charge $44 extra they never mention they will charge, it was for their service using their website to booking the fly. Cheap on Air? Not at all. That is not the right way to do business. WORSE EXPERIENCE EVER.
