When’s the best time to book plane tickets to get cheaper flights?

According to travel app Hopper, the idea that Tuesday is the best day to book cheap flights is a myth. The belief originated from a time when airline prices were manually adjusted on Mondays if routes weren’t selling well. However, with the advent of dynamic pricing and automated computer models, the lowest fares can be found on any day of the week. Instead, Hopper suggests picking midweek departure dates, being flexible with travel dates, booking domestic flights a month ahead, and planning ahead using price monitoring systems.
