The ITA Matrix is a powerful, research-only flight search engine developed by ITA Software and acquired by Google in 2010 to power Google Flights. It allows advanced travelers to use routing codes and data visualization tools to find complex, low-cost itineraries that cannot be booked directly. For more details on using this tool, visit Upgraded Points.

  1. Google Flights API (via QPX Express): While discontinued, legacy partners can still request enterprise access. The SOM logic lives inside Google's internal AirportMatrix service.
  2. Routehappy / ATPCO: The modern successor to fare matrices is ATPCO’s Routehappy API, which uses a similar "uber-matrix" for ancillary fare families.
  3. Duffel (Modern Alternative): Duffel’s Booking API uses a matrix response structure heavily inspired by ITA. Their documentation sometimes references offer_matrix and sort_by="som" (Sourced Optimization Metric).

The travel industry has undergone significant transformations over the years, driven by technological advancements and changing consumer behaviors. One of the key developments that have impacted the way travel agencies and airlines operate is the introduction of matrix-based software solutions. Among these, Matrix:ITA Software has emerged as a leading platform, revolutionizing the way travel professionals plan and manage itineraries.
