Guess what? It turns out that early in the week is the best time to score the cheapest plane tickets. Looking at flight demand on Wotif in 2021, we found that flights purchased on a Monday had the lowest airfares on average. Booking your plane ticket on the weekend also seems to score pretty good deals.

On the other hand, the month of December can be one of the most expensive times to travel, with the highest average ticket price, so it's best to get in early if December is your preferred travel month.
How far in advance can you book a flight?
