Flying from Canada can be expensive — domestic flights within Canada are often pricier than international ones. But with the right strategies, you can consistently find great deals. Here's everything you need to know about booking cheap flights from Canada.

Book at the Right Time

Timing is everything when it comes to airfare. For domestic Canadian flights, book 1-3 months in advance. For international flights to the US or Caribbean, 2-3 months ahead is ideal. For transatlantic or transpacific flights, 3-6 months in advance typically yields the best prices.

Use Canadian Budget Airlines

Canada's airline market has more options than you might think. Flair Airlines offers ultra-low-cost fares on domestic and US routes. Swoop (now part of WestJet) provides budget options as well. Porter Airlines has expanded beyond its Toronto City base to offer competitive transcontinental fares. Lynx Air may also serve your route.

  • Flair Airlines — Ultra-low-cost fares on domestic and US routes
  • Porter Airlines — Premium economy experience, expanded routes from Billy Bishop
  • WestJet — Major Canadian carrier with domestic and international routes
  • Air Canada — Canada's flag carrier — Aeroplan points earning

Fly from US Border Airports

One of the best-kept secrets for Canadian travellers is flying from US airports near the border. Buffalo (BUF) for Ontarians, Bellingham (BLI) for British Columbians, and Plattsburgh (PBG) for Quebecers can save you 30-50% on international fares compared to flying from Canadian airports.

Set Up Fare Alerts

Use CanadaFlies to search and compare prices across hundreds of airlines. Set fare alerts on Google Flights and Skyscanner for your desired routes. Follow deal accounts on social media — Secret Flying Canada and YVR Deals post error fares and sales regularly.

Consider Positioning Flights

If you live in a smaller Canadian city, sometimes booking a separate cheap flight to a major hub (Toronto, Vancouver, Montreal) and then taking your international flight from there can be significantly cheaper than booking the entire route. Just make sure to leave plenty of connection time.

Use Points and Miles Strategically

Aeroplan (Air Canada), WestJet Rewards, and credit card travel points like Amex Membership Rewards and TD Travel Rewards can dramatically reduce your costs. The key is earning points through everyday spending on the right credit cards and redeeming them at the highest value.

  • Aeroplan points are worth roughly 1.5-2 cents each when redeemed well
  • WestJet dollars are straightforward at 1 cent each
  • Amex Membership Rewards transfer 1:1 to Aeroplan
  • Sign-up bonuses on travel credit cards often cover a round trip to Europe

Watch for Mistake Fares

Airlines occasionally publish fares with pricing errors. These "mistake fares" can save you 50-80% off normal prices. Most airlines now honor these fares if you book quickly. Follow flight deal communities online to catch them within the short window they're available.

Finding cheap flights from Canada is a skill anyone can learn. Combine these strategies, stay flexible with your dates and destinations, and you'll be flying for less in no time.
