Google just announced about its purchase of ITA, a Cambridge, Massachusetts based Flight information provider for to airlines, travel agencies, and online reservation systems. Basically, it is the center of flight data.
A consortium of rivals including Microsoft, Kayak, Expedia, and Travelport; has tried to stop Google from getting it's hands on ITA by trying to beat Googles offer, last spring. But Google’s $700 million was bigger than theirs, I guess. Microsoft, Kayak, Expedia, and Travelport rely on ITA for their flight data needs.
