Since flights towards the middle of the week tend to be more popular, this causes the prices to rise. This is why, on average, airfares booked on Travelocity.ca in 2021 were most expensive for Wednesday departures.

Here's the deal: It is typically possible to start comparing international airfares on Travelocity.ca up to 12 months in advance.
