Jetsetter, the exclusive travel community for globetrotters, seems to be on a roll. In recent days, the company has announced a dozen some new corporate partners, a handful of new sale formats to entice customers, and new distribution partnerships with high-profile sites like Kayak, The Economist and the vacation rental service HomeAway. But while many think of Jetsetter as a flash sales for travel site, it's been finding growth in other verticals: curated recommendations and personal service.
