Frequently asked questions

Is it cheaper to buy a plane ticket from CPS to Brussels - National Airport (BRU) last minute?
When it's time to book your flights, it pays to be prepared. While it's possible to score a deal on a St. Louis Downtown Airport to BRU flight at the last minute, prices usually don't get cheaper as the date of departure nears. Based on flight pricing and demand studies in 2022, we have found that the sweet spot to book a domestic flight is between 28 – 35 days ahead. For international travel it's three to four months.

From East St. Louis, you can travel to Brussels through Brussels - National Airport (BRU), Antwerp Intl. Airport (ANR) and Malle (OBL-Zoersel-Oostmalle Airfield). Determine which terminal is right for you before you make a decision. If you opt for Brussels - National Airport (BRU), it's roughly 11 kilometers northeast of the center of the city. Use the money you save when booking your fare with Expedia to enjoy the city's popular attractions, such as La Grand Place and Atomium.
Can I change the date of my flight from St. Louis Downtown Airport (CPS) to Brussels - National Airport (BRU)?
You can easily make changes to your CPS to BRU ticket by logging in to the Expedia Trips portal. But before you begin, browse the rules in your itinerary to see what you can do and if fees apply.
