Frequently asked questions

Is it cheaper to buy a plane ticket from STL to RSD last minute?
When it comes to booking your flights, being prepared pays off. While it's possible to pick up a last-minute deal on a STL to Rock Sound Airport flight, tickets usually don't get cheaper as the departure date nears. Based on flight pricing and demand studies in 2022, we have found that the sweet spot to book a domestic flight is between 28 – 35 days ahead. For international travel it's three to four months.
