ITA and Kayak were both founded in the Boston area. I've never really figured out why travel sites seem to have such a base in the Boston area. Anybody have ideas? Proximity to Logan for international travel? MIT and Harvard being located there hence lots of travel...?

Founders of ITA were MIT grads, and hired lots of MIT folks. (Former ITA Software employee here - though not an MIT grad). ITA has been around for over a decade FWIW.
