Air charter firm XOJet announced today that it achieved more than a 30-percent year-over-year growth in flight hours last year. The company said its continued growth has been limited only by fleet size, since it claims demand has consistently exceeded capacity. To drive continued growth this year, XOJet is focused on expanding its fleet. In fact, the company placed an order for 12 Hawker Beechcraft Hawker 800XPr twinjets in October and introduced seven of these aircraft into its fleet this month.
