| Goal | Syntax Example | |------|----------------| | Avoid a specific airline | -UA | | Prefer an alliance | *A (Star Alliance) | | Only nonstop flights | N in routing | | Only specific booking class | f bc=K | | Weekend trips only | Use Saturday stay filter |

For the software engineers reading this, let’s simulate the logic of matrix.ita software.som.

The Problem: 10,000 flights JFK to LAX. Combining them with 5,000 connecting flights yields 50M itineraries. matrix.ita software.som

The ITA SOM Solution:

Result: Sub-second response times with 99.999% accuracy on valid fares. | Goal | Syntax Example | |------|----------------| |

New data scientists at Delta, American, and United are often required to reverse-engineer legacy systems. The SOM matrix is taught as the "gold standard" for solving the NP-Hard problem of fare combinability. Understanding how ITA structured its matrix allows modern engineers to build better AI-driven pricing engines.

The Bad News: You cannot. Google never open-sourced ITA’s core matrix software. The public endpoint matrix.itasoftware.com/search redirects to Google Flights. Result : Sub-second response times with 99

The Workarounds:
