TraqPak data released yesterday by aviation services company Argus shows that business aircraft flying in the U.S. rose for the 12th month in a row in November, climbing 3.7 percent year-over-year. While this was a solid gain, it was slightly below Argus’s estimate of 3.9 percent.

All operating segments recorded increases last month, and Part 135 charter activity led the way with an 8.6-percent rise. This was followed by a 3.3-percent lift in fractional flying and a 0.8-percent advance at Part 91 operations.

In addition, flight activity was positive across all aircraft categories last month. Large-cabin jets posted the largest expansion, rising 6.7 percent year-over-year. Light and midsize jet flying jumped 2.8 percent and 5.4 percent, respectively, while turboprop activity was up by 1.5 percent.

By individual segment, Part 135 large-cabin jet flying logged the biggest uptick at 19.8 percent. Other double-digit gains in activity included charter midsize jets, up 11.1 percent, and fractional turboprops and light jets, which rose 16.9 percent and 13.9 percent year-over-year, respectively. Only two individual categories experienced erosion last month: fractional midsize jets slid 1.9 percent and Part 91 turboprops dipped 2.8 percent from a year ago.
