UK Business Jet Movements YTD Crash 8.5%; Pre-APD Tax Reform Demand Accelerates Outflow

January 1 – May 19, 2026, UK business jet movements 59,511 — YoY −8.5% (−5,562) — largest decline among European six major markets. May first 19 days YoY crashed 14.2% — downtrend accelerating clearly. Combined with KG events: UK from April 2027 will substantially lower Air Passenger Duty (APD) tax threshold from 20 tons to 5.7 tons — directly covering vast majority of light and midsize business jets. Policy anticipation has already pre-suppressed demand — operators and clients may be relocating flight activity to European continent. By contrast, Italy grew +2.8% against trend; Southern Europe is absorbing Northwest European spillover demand. For brokers and operators: UK-departure route pricing power and customer retention face severe challenges. Confidence ★★★ (Avi-Go six-country data + KG APD policy event dual cross-verification).
