Frequently asked questions

Is it cheaper to buy a plane ticket from Lambert Field to Casper Airport last minute?
Being the spontaneous type is a fabulous way to see the world, but it isn't always the best way to track down a bargain airfare. Think about booking your STL to Casper Airport trip well in advance rather than waiting till the last minute. 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 reach your destination!
