Frequently asked questions

Is it cheaper to buy a plane ticket from Ottawa Intl. Airport to St. Louis Downtown Airport last minute?
Booking your trip from Ottawa Intl. Airport to CPS at the last minute could save you a pretty penny if you're lucky enough to find an epic deal. However, fares generally don't get cheaper as the date of departure nears. If you choose to wait, flights could also be booked out or the best seats taken (because who wants the middle seat?). If you'd rather play it safe, book well ahead of when you want to leave. In fact, some of the best deals are available on Expedia up to 12 months in advance. If your favorite carrier hasn't released its fares yet, check back regularly as deals are constantly updated on Expedia.

With St. Louis Downtown Airport (CPS), Lambert-St. Louis Intl. Airport (STL) and MidAmerica-St. Louis Airport (BLV) to select from, making your way from Ottawa to East St. Louis is a breeze. The city's main hub, St. Louis Downtown Airport (CPS), is roughly 3 kilometers south of the center.
