Pre-Owned Gulfstream G650ER Utilization Soars 12.1% YoY to 116.5 Annual Movements per Aircraft — Standard G650 Becomes the Only Declining Type in the Series; ER Variant Value Premium Continues to Widen

★★★ AviGo data reveals significant internal divergence within Gulfstream G650 series: G650ER 2025 full-year flight volume at 36,590 was +12.1% YoY; annual per-aircraft movements rose from 103.9 to 116.5. Standard G650 flight volume declined 2.3% YoY — the only Gulfstream type to decline among six. G650ER per-aircraft utilization is ~50% above standard G650 (116.5 vs. 77.6 movements/year). Hagerty Jet Group reports extreme pre-owned Gulfstream scarcity overall, but this divergence means the ER variant's pre-owned price premium will further widen, while standard G650 faces dual diversion pressure from ER and G700. For brokers and asset managers, standard G650 residual-value downside risk is accumulating.
