📉 KOSH Aircraft Movements Fall to 105 After Previous-Window Peak
Business aviation activity at KOSH contracted significantly across two consecutive 14-day windows, with the elevated levels seen from late July to early August proving unsustained. Avi-Go data show that from August 8 to August 21, 2026, KOSH recorded 53 business aircraft departures and 52 arrivals, for a total of 105 movements. Compared with 376 departures, 74 arrivals, and 450 total movements from July 25 to August 7, departures decreased by 85.9%, arrivals declined by 29.7%, and total business aircraft movements fell by 76.7%. Under the airport-based methodology, each departure or arrival counts as one movement. This short-window change confirms that the concentrated activity in the previous window has subsided, but it should not be used to assess the long-term trend in local charter demand.
Impact: Of the 450 movements in the previous window, 376 were departures, representing a significant difference in the arrival-departure mix compared with the nearly balanced 53 departures and 52 arrivals in the subsequent window. For local FBOs and operators at KOSH, using the service intensity from July 25 to August 7 as the baseline for routine resource planning could lead to mismatches between actual activity and subsequent staff scheduling, parking-stand coordination, and ground service preparations.
Recommendation: FBOs serving KOSH may use the average of 7.5 daily movements from August 8 to August 21 as a reference for near-term staffing and supply preparations, while treating the average of 32.1 daily movements from July 25 to August 7 separately as a concentrated-activity scenario rather than incorporating it directly into baseline demand. Going forward, it will be worth monitoring whether departures and arrivals continue to maintain a ratio close to 1:1 and whether business aircraft movements across consecutive full 14-day windows stabilize near 105.
