Is it cheaper to buy a plane ticket from St. Louis Lambert International Airport to Petersburg James A. Johnson Airport last minute?
Being the spontaneous type is an amazing way to discover the world, but it isn’t necessarily the ideal way to track down a bargain airfare.

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.
