US-Israel-Iran Conflict Transmission Effect Erupts in April: European Six-Country Business Jet Movements Crash 18.4% YoY — Daily Average Down ~450 Movements

Between April 1–17, 2026, six European countries (France, Germany, UK, Spain, Italy, Switzerland) combined business jet movements at just 34,154 vs. 41,871 in same period of 2025 — YoY −18.4%; MoM vs. March −17.5%. Daily-average movements fell from ~2,463 to 2,009 — daily-average down ~454. Key point: March 2026 was only 1.1% below April 2025, indicating transmission effect concentrated in April — closely aligned with Jet-A retail price +19.2% timing window. Near 20% YoY decline is rare in European business aviation — operators and charter clients clearly compressed flight demand under high-fuel-price environment. Note: the geopolitical conflict context here refers to the US-Israel-Iran war mentioned in search results; Strait of Hormuz blockade is only one possible transmission path — actual transmission mechanism may be more complex. Confidence ★★ (AviGo data clear, but lacks operator-level fuel surcharge adjustment confirmation; geopolitical-conflict-to-fuel-price causal chain still requires more evidence).
