Jet card company Sentient Jet said that 2013 was its best year since 2008. The company sold more than 32,000 hours last year, the equivalent of some 1,300 twenty-five-hour jet cards, and expanded its revenue to more than $150 million. “We could not be more pleased with our 2013 performance, which included our best summer since 2008 and best holiday flying season since 2007,” noted Sentient Jet president Andrew Collins. Sentient also said its top-five busiest airports last year were (in this order): Teterboro, N.J.; West Palm Beach, Fla.; Aspen; Las Vegas; and San Francisco.
