RE:From CIBC Aerospace weeklyFrom ainonline article dated April 20th "Worldwide, business jets flew 70,657 sectors during week 15, which is a decrease of 4 percent from the same week a year earlier. In the last four weeks the global trend for business jet activity fell 9 percent compared with the same period in 2022, WingX said".

IADA analysis is inline with other outlet which track business jet activities.
Unless i misread, Cibc skipped 2020, 2021, and 2023 to compare it to 2019. Ainonline article breaks down the traffic by region too, and they are all down from last year.
