The best day to book your flights

Travellers who book on Sundays instead of Fridays tend to save, on average, around 20 per cent on domestic flights and 18 per cent on international flights, Expedia found.

Aussies should also aim to book domestic flights at least 14 weeks before travel and international flights at least a month before travel.

Travellers who booked their domestic flights at least 14 weeks prior to departure also saved 20 per cent, on average, compared to those who waited until the last minute.

International airfares tend to be rather stable during the six-month period prior to travel but, for optimal availability, selection and savings, it’s best to book at least a month out.

The cheapest day (and time) to depart

Departing on a Friday could save Aussies up to 23 per cent, Expedia found. It’s also best to avoid departing on Sundays, which are the priciest days, on average, to start a trip.

To save yourself some pain, travellers should aim to depart after 3:00pm to reduce the chance of a cancellation.
