Indonesia Dual-Hub Business Jet Movements Stand Out in Avi-Go Sample, but Comparison With Singapore/Bangkok May Be Distorted by Airport Selection Bias

Avi-Go data shows January 1 – May 10, 2026 Jakarta WIII (570 movements) + Bali WADD (374) combined 944 — relatively high share among selected SEA four major hubs. Bali active operators 50 leads — reflecting international business jets' demand for Indonesia high-end leisure destination. However, this comparison has important limitation: Singapore business jets primarily use Seletar (WSSL) rather than Changi (WSSS); Bangkok Don Mueang (VTBD) also absorbs some business jet flow. If data only counts WSSS and VTBS, Singapore and Bangkok business jet data may be severely undercounted — Indonesia-to-the-two ratio gap should not be cited as reliable conclusion. KG shows ExecuJet and Jet Aviation two major global FBO operators have no direct operating facilities in Indonesia — infrastructure supply and flow may have mismatch. For FBO investors and MRO service providers: Indonesia market warrants further evaluation, but needs to be based on more complete regional airport data. Confidence ★★ (Indonesia flow data itself referenceable; cross-region comparison reliability reduced by airport selection bias).
