Travel is a lot like real estate: Timing and location are the keys to get maximum value. To help you get a better handle on vacation planning, the data experts at Cheapflights.ca crunched data from 4.5 million flight searches to 20 of the most popular destinations to find out when airfares from Canada are at their lowest and their highest -- and when the best prices tend to be available for booking.
All our number crunching about the best time to buy flights reveals some key findings:
- Some destinations (we're looking at you, Cancun and Costa Rica) are better suited to the last-minute travel planner than others (say Vancouver and Los Angeles, for example).
- The holiday season is really the most expensive time to fly. The last couple weeks of the year topped the list for priciest flights to all but one destination. It's best to make your Christmas or New Year's plans over the summer.
- It's not too late to plan a bit of pre-Valentine's Day romance in Paris, but you better get cracking.
- If you want to take full advantage of January travel deals (and there are many), make peace with it being next year.
- Now is the time to focus on spring and summer travel plans.
