Frequently asked questions

Is it cheaper to buy a plane ticket from WBU to STL last minute?
Being spontaneous is a fabulous way to travel, but it's not necessarily the smartest way to pick up a bargain airfare. Consider booking your WBU to STL journey ahead of time rather than waiting until 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. Save all that spontaneity for when you arrive in STL!
What airports do you fly into for St. Louis from Boulder?
From Boulder, you can reach St. Louis through Lambert-St. Louis Intl. Airport (STL), Spirit of St. Louis Airport (SUS) and St. Louis Downtown Airport (CPS). It's a good idea to check which terminal is right for you before making your decision. If you choose Lambert-St. Louis Intl. Airport (STL), it's roughly 19 kilometers northwest of the downtown area. Use the dough you save when booking your fare with Expedia to enjoy the city's awesome attractions, such as Busch Stadium and Gateway Arch.
