While much of the aviation industry struggles, an Atlanta-based air-taxi company is enjoying strong growth. Founded by a couple of Georgia Tech student pilots who met through the Yellow Jacket Flying Club, ImaginAir boasts 15 employees and a fleet of five fuel-efficient Cirrus SR22 GTS aircraft. "It really opens up point-to-point transportation for the first time," says CEO Aaron Sohacki. ImaginAir has flown more than 600 routes at about one-third the cost of a typical air charter, a price advantage that is fueling the company's growth. "We basically doubled our business from 2007 to 2008, and we think we can easily double that for the rest of the year," says company President Ben Hamilton.
