The ITA Matrix uses algorithms. It can scan hundreds of billions of fare combinations in one second. The result is the famous "Calendar Grid"—a color-coded chart showing you the cheapest day to fly in the next 11 months at a single glance. The Secret Weapon: Advanced Routing Codes Where the Matrix truly shines (and scares beginners) is the Advanced Routing Code . There’s a code for that
