The previous school of thought was that Tuesday was the best time to book a flight, but ARC disputed that theory.
ARC analysed both US domestic and international airfares between January 2013 through July 2014, and found that the lowest average airfare was available on Sundays. Travellers who booked flights on Sundays paid an average $US432 for domestic flights and $US958 for international flights.
