ITA Software

ITA Software is a travel technology company, now part of Google, that builds airfare pricing, shopping, and availability software for airlines, online travel agencies, and travel management companies. Founded in 1996 in Cambridge, Massachusetts by MIT computer scientists (notably Jeremy Wertheimer) and backed early by Battery Ventures, General Catalyst, and Sequoia Capital, the company was acquired by Google in 2011. Its flagship QPX engine powers pricing, revenue shopping, ticket rebooking, award-flight search, ancillary merchandising, and flight schedule/seat availability for carriers including Air Canada, American Airlines, Delta, United, and Virgin Atlantic, and its technology underpins Google Flights. ITA Software also operates the consumer ITA Matrix flight-search tool at matrix.itasoftware.com. The former public QPX Express REST API was retired by Google in April 2018; today ITA Software's QPX solutions are delivered as an enterprise engagement through Google account teams, with no public self-service developer program, portal, or SDKs.

ITA Software is profiled on the APIs.io network. Tagged areas include Company, Travel, Airlines, Airfare, and Flight Search.

ITA Software’s developer surface includes tooling and 3 more developer resources.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/ita-software: open an issue to ask a question, or submit a pull request to add artifacts.
