Frequently asked questions

Is it cheaper to buy a plane ticket from Spirit of St. Louis Airport (SUS) to Charleston Intl. Airport last minute?
Being the spontaneous type is a rewarding way to travel, but it's not necessarily the best way to get your hands on a cheap flight.

Based on flight pricing and demand studies in 2022, we have found that the best time to book domestic flights is between 28 – 35 days ahead of the departure date, and international flights three to four months in advance. We recommend saving that spontaneity for when you're discovering Charleston Intl. Airport (CHS)!
