Frequently asked questions

Is it cheaper to buy a plane ticket from Montréal–Trudeau to St. Louis Airport last minute?
Booking your flight from Montreal Airport to St. Louis Airport at the last minute could save you some dough if you strike it lucky and find an amazing deal. However, fares don't typically get cheaper closer to the departure date. If you wait around, flights could also be booked up or the best seats taken (because who wants the middle seat?). If you'd prefer to play it safe, book well ahead of the date 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 favorite carrier hasn't released its fares yet, check back regularly as deals are updated on Expedia all the time.
What airports do you fly into for St. Louis from Montreal?
Spirit of St. Louis Airport (SUS), Lambert-St. Louis Intl. Airport (STL) and St. Louis Downtown Airport (CPS) are your choices when jetting off from Montreal to St. Louis. Around 40 kilometers west of downtown St. Louis, Spirit of St. Louis Airport (SUS) is the city's principal gateway. Keep in mind things like flight arrival and departure times and the distance to your hotel before choosing an airport. Busch Stadium and Gateway Arch are a couple of amazing attractions to put on your itinerary when you get to your destination.
