KBFI Business Jet Movements YoY +7.9%; KPDX Down 7.3% — Pacific Northwest Dual-Hub Flow Accelerates Divergence

★★ Avi-Go data + industry news corroboration. January–May 2026 KBFI (Boeing Field) business jet movements reached 15,280 (YoY +7.9%); arrival growth up to 12.8% — indicating Seattle's appeal as destination is strengthening. KPDX (Portland) fell to 4,481 (−7.3%); departure decline 8.8%. Operator-level divergence synchronous: NetJets grew +6.5% at KBFI but declined −12.7% at KPDX; Flexjet grew +7.2% at KBFI but crashed −19.1% at KPDX — resources clearly concentrating toward Seattle. Note: Aero Air and Boutique Air recorded notable growth in Avi-Go data, but both are primarily cargo, commuter, and Essential Air Service feeder flights — whether their flights are strictly categorized as business aviation depends on data covering broad Part 135 — operator-level growth/decline magnitudes should be understood under this methodology. Although KBFI flow strengthening, this region currently has no FBO expansion or new operator entry public reports; FBO investment hotspots still concentrated in Florida and Texas.
