There's no definitive rule for which days are best to fly for cheap flights to all destinations. Every airport and place is a little different and have their own specific days and times when there's less travelers usually flying in and out, creating a higher surplus of available seats with less demand and causing airlines to charge less.
There's also seasonal and holiday travel, which creates more demand and lowers any chance of cheap flights. But there is a general pattern in how most people travel that you can take advantage of to save money on airline tickets.
Most people will book to fly on Friday and the weekend and that's why flights on those day are generally the most expensive. So, just being willing to fly Monday through Thursday will increase the likelihood of snagging cheap flights.
