JET LINX AVIATION “Demand for private jets is far from robust, but at the margin some developments suggest improvement,” J.P. Morgan aerospace analysts said in their latest business jet monthly update, released Sept. 10. Among these positive developments, U.S. flight operations climbed 4.7 percent year-over-year in July, which the investment firm said is the best result since May 2011 and the fourth consecutive month of year-over-year growth.

“It has been hard to imagine a broad-based recovery without U.S. operators flying more, and recent data shows an important step in this direction,” wrote J.P. Morgan aerospace analyst Joseph Nadol III. The firm also estimates that the material downtick in the proportion of young aircraft for sale (five years old or less), which it noted in last month’s report, “remained steady in August.”
