Frequently asked questions

Is it cheaper to buy a plane ticket from DEC to CPS last minute?
Booking your trip from Decatur Airport to St. Louis Downtown Airport (CPS) last minute could save you a pretty penny if you luck out and find a real steal. However, tickets usually don't get cheaper as the date of departure nears. If you wait around, flights could also be sold out or the best seats taken (we hope you like the middle seat!). If you'd rather not take any chances, book well in advance of when you want to leave. It's worth noting that some of the best deals can be found up to a year in advance. If your preferred carrier hasn't released its airfares yet, check back regularly as deals are constantly updated on Expedia.
What airports do you fly into for East St. Louis from Decatur?
St. Louis Downtown Airport (CPS), Lambert-St. Louis Intl. Airport (STL) and MidAmerica-St. Louis Airport (BLV) are your choices when flying from Decatur to East St. Louis. Roughly 3 kilometers south of central East St. Louis, St. Louis Downtown Airport (CPS) is the city's principal entry point. Consider factors such as flight arrival and departure times and the distance to your hotel before settling on an airport. Busch Stadium and Gateway Arch are a couple of amazing attractions to put on your to-do list when you arrive at your destination.
