What is the cheapest day to book a flight in Canada?

Tuesday and Wednesday are typically cheapest for booking. Airlines often release sales on Monday night/Tuesday, and mid-week flights have lower demand. Sunday tends to be most expensive.

How far in advance should you book flights in Canada?

For domestic flights, book 1-3 months ahead. For international, 2-8 months ahead depending on destination. Last-minute deals exist but are unpredictable. Booking too early can also mean higher prices.

Do flight prices go down on Tuesday?

Often yes. Airlines frequently release fare sales Tuesday mornings, and competitors match prices by afternoon. Prices tend to be lowest Tuesday through Thursday for both booking and flying.

Is it cheaper to book one-way or round-trip flights in Canada?

It depends on the airline. Budget carriers like Flair and Porter often price one-way tickets at half the round-trip cost, so mixing airlines for each leg can save money. Air Canada and WestJet sometimes offer round-trip discounts, so always compare both options. Google Flights lets you search one-way and round-trip side by side.

Best Day to Book Flights Canada 2026 | Cheapest Days, Times & Booking Windows

Timing alone can save you $100–$200 on a domestic Canadian flight and even more on international routes. Airlines typically release fare sales on Monday nights and Tuesday mornings, which means Tuesday afternoon — after competitors have matched prices — is consistently the cheapest window to book. Flying mid-week (Tuesday or Wednesday) instead of Friday or Sunday shaves another 20–40 % off the ticket. Combine flexible dates with the right advance-booking window — roughly 3–6 weeks for domestic, 2–4 months for international — and you’ll pay near the lowest available fare without relying on unpredictable last-minute deals. Below is a breakdown of the best days, seasons, and strategies to keep airfare as low as possible, plus tips for stacking savings with travel credit cards and price-tracking tools.
