The Matrix series of films was a rare combination of complex storytelling and a financially successful film franchise, but an even more richly opaque Matrix is ITA Software’s Matrix Airfare Search.
In the right hands, the Matrix Airfare Search can be a very powerful tool for finding flights at the right price. Like the better known search engines such as Orbitz, Expedia, and Kayak, the Matrix allows you to search with a flexible date range, restrict airlines, and even select nearby airports for an origin and destination.
However, the Matrix also offers powerful tools for frequent travelers, such as restricting a search by an alliance, forcing connections at specific airports, and searching for available flights with availability in certain fare booking codes. I used it frequently during my mileage running days before earning elite status and, more recently, multi-city bookings became much more difficult.
Once you’ve used the Matrix, you might be ready to move on to the advanced functions it offers frequent flyers. Google, which owns ITA Software and its Matrix Airfare Search tool, published a guide for the advanced routing codes that will search for flights using a variety of criteria. I recommend checking it out. However, if you feel like you need a basic primer on using the advanced routing codes, the folks at Upgraded Points list tips for finding the right flight using the Matrix.
Both guides are very long and detailed, but knowing how to maximize the potential of this flight search tool could help plan the right itinerary for you. It helped me when I used to care more about flying frequently.
