Sorry we didn’t get to this one earlier today, but Farecast, a pretty cool service that helps you predict and ensure the best time to buy air flights, has raised $12.1 million from Sutter Hill Ventures, PAR Capital Management, Pinnacle Ventures, Erik Blachford, Greylock Partners, Madrona Venture Group, and WRF Capital, for a total of $20.6 million raised. We’d written about the company before. What used to be a nice little acquisition target is getting quite large on its own!
