Business aviation flights in the U.S. and Canada topped 3 million last year, reaching that mark for the first time since 2008, according to a 2017 Business Aircraft Activity Review released today by Argus International. The 30-page review, which details Argus TraqPak flight activity data in 2017, reports that business aviation flights increased 3.9 percent overall and flight hours jumped 5.5 percent over 2016.

Year-over-year gains were posted in every month of 2017, Argus said, adding that the improvements were fairly consistent throughout the year. Activity in the first half of 2017 was up 3.9 percent over the same period in 2016, while activity in the second half of 2017 was up 3.8 percent.

Part 135 operations enjoyed the greatest gains, rising 9.2 percent last year. This improvement was driven by Part 135 large-cabin jet operations, which led all increases in 2017 with a 14.9 percent jump. Fractional flights ended the year up 4.7 percent, while Part 91 flights inched up 0.1 percent in 2017. Increased Part 91 large-cabin and midsize jet flights—up 2.9 percent and 1.2 percent, respectively—offset a slide in Part 91 light jet flights, down 0.7 percent, and turboprop flights, down 1.3 percent.

Flights across the board has consistently increased since 2014, rising from 2.80 million that year to 3.06 million last year—a 9.4 percent improvement.
