Sentient Jet’s private jet travel and jet card sales continue to grow year-over-year, reaching levels not seen since before the onset of the financial crisis in 2008, the company said yesterday. “We started to see a sharp increase in jet card sales at the beginning of the year–a trend that continued throughout the summer,” said Sentient Jet president Andrew Collins. “We sold about 11,000 hours from May through August, equating to roughly 450 jet cards, and saw a 10-percent increase in total hours flown over this period last year.” In response, Sentient has expanded its jet card offerings by adding a 25-hour card for both super-midsize jets and large-cabin jets.
