Business aircraft operations in the U.S., Caribbean and Canada jumped 5.3 percent year-over-year last month, thanks to solid across-the-board gains, according to the latest Argus Business Aircraft Activity report. The business aviation data firm expects the improvements to continue, predicting a 3.9 percent increase for this month.

Based on the Argus TraqPak IFR arrival and departure data, large-cabin jet flying surged 8.8 percent from a year ago, with midsize jet activity not far behind with a 7.7 percent increase. The lighter aircraft categories experienced smaller gains. Turboprop and light jet activity rose 3.3 percent and 2.9 percent, respectively.

Looking at the data by operator, Part 135 charter flying soared 11.3 percent from April 2016, while fractional activity logged 8.5 percent growth. Meanwhile, Part 91 flying increased 0.5 percent year-over-year.

Several double-digit gains were seen in individual categories. In fact, Part 135 midsize and large-cabin jet flying each recorded 20 percent gains from a year ago, while fractional turboprop and large-cabin jet activity climbed by 22.2 percent and 14 percent, respectively. Only Part 91 light jets posted a loss, falling 0.9 percent from last April.
