What are the cheapest days to fly?
Here's an insider tip: Monday is typically the cheapest day to fly! Looking at flight demand on Wotif in 2021, we found that flights departing on a Monday generally had the lowest average price, closely followed by flights on a Saturday. You might want to think twice about flying on a Thursday though; generally, our data showed that it had the highest average ticket price.
What is the best day to buy a plane ticket?
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. However, airfares purchased on a Friday generally have a higher than average ticket value, so you might want to prepare your budget if you're booking on that day.

When comparing airfares booked through Wotif in 2021, our data shows February is one of the cheapest months to fly. 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?
Trying to figure out how early you should book your flight? It's possible to start comparing international airfares on Wotif up to 12 months in advance. However, it does depend on the carrier as not all airlines release their prices that far out.
