Methodology: learn how we calculate these figures

The best day to fly and how far ahead to book shown in this table are built from the prices Priceline customers actually paid for flights to this destination over the past 12 months or more.

Where a route has too few bookings to fill a figure, we borrow the shape from a group of routes with similar price behavior and fit it to the fares booked on that route.

Because past fares don’t reflect today’s market, we then adjust the historical prices for current conditions such as inflation and fuel costs, using the round-trip fares found in recent searches.

The cheapest round-trip and one-way fares, the good-deal price and the best time of day to fly come directly from the fares found in recent searches, not from historical bookings.

Where a route has too few bookings to fill every point in a chart, we borrow the shape of the curve from a group of routes with similar price behavior and fit it to the fares booked on this route.

Frequently Asked Questions

Everything you need to know about flying from St. Louis to Canada.

When is the cheapest time to fly from St. Louis to Canada?

The cheapest months to fly from St. Louis to Canada are January, September, and February, each about 5% below the yearly average, with the very lowest fares found in late January. The priciest months are December and June, running 9% and 7% above the yearly average respectively, with late December the single most expensive period. These figures come from the busiest city pairs between St. Louis and Canada, including Toronto and Vancouver.

Methodology

These seasonal fares look at the busiest city-to-city routes between the two places (up to four, chosen by scheduled flights) and at the seasonal fare curve Priceline's own archive provides for each route. Months are ranked by how far each month's average fare sits above or below that route's yearly average, taking the middle value across the routes, so one expensive route cannot dominate.

How far in advance should I book flights from St. Louis to Canada?

For St. Louis to Canada, the best booking window is 25 to 45 days before departure, with the lowest fares typically about 4 weeks out. Fares do rise when booking very early, as prices at 180 days out run higher than at 30 days out on both the Toronto and Vancouver city pairs.

Methodology

This booking-window guidance looks at the busiest city-to-city routes between the two places (up to four, chosen by scheduled flights) and at the booking-window fare curve Priceline's own archive provides for each route. The best time to book is the middle value of those routes' cheapest lead times.

What are the most popular cities to visit in Canada?

Popular Canadian cities from St. Louis include Toronto for urban culture and Niagara day trips, Montreal for French heritage and festivals, Vancouver for mountains and ocean, and Calgary as a gateway to Banff.

When is the best time of year to visit Canada?

For Canada, May to June and September to early October balance good weather with lighter crowds and lower prices than the busy July and August peak in gateway cities like Toronto, Montreal and Vancouver.

How do I get to Lambert Intl Airport from the city center?

The fastest and most popular way to reach Lambert International Airport from downtown St. Louis is by ride‑share or taxi, with curbside pickup at both terminals and a typical drive of 12 to 15 miles via I‑70. MetroLink light rail runs directly from downtown to the airport and is the most affordable option, though it takes longer. Several airport hotels offer shuttle buses, and driving yourself is straightforward with on‑site garages and surface lots at both terminals, plus free cell phone lots for drop‑offs.
