When I posted the list earlier from Money.com, I forgot to add something to rule #23.

When it comes to buying airline tickets, almost everyone knows that buying in advance saves money. But not many people konw to check for airline tickets on Wednesday from midnight to 1a.m. in the time zone where the airline is headquartered. That’s when the computer systems of most airlines get rid of the reserved but unbooked lower fare reservations. You will most likely get a pretty good discount at that time.
