Frequently asked questions

Is it cheaper to buy a plane ticket from Baton Rouge Metropolitan Airport to St. Louis Downtown Airport (CPS) last minute?
Being the spontaneous type is a wonderful way to travel around, but it isn't always the ideal way to get your hands on a cheap airfare. It's better to book your BTR to CPS trip well in advance 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 reach your destination!
What airports do you fly into for East St. Louis from Baton Rouge?
From Baton Rouge, you can journey to East St. Louis through St. Louis Downtown Airport (CPS), Lambert-St. Louis Intl. Airport (STL) and MidAmerica-St. Louis Airport (BLV). Determine which airport works best for you before you make a decision. If you choose St. Louis Downtown Airport (CPS), it's approximately 3 kilometers south of downtown. Use the cash you save when booking your seat with Expedia to tour the city's awesome attractions, such as Busch Stadium and Gateway Arch.
Can I change the date of my flight from BTR to CPS?
