Abstract: This paper assesses network connectivity at major Asian airports using the NetScan quality model, measuring direct, indirect, and hub links in Connectivity Units. Using a one-week OAG schedule (15-21 June 2024), valid itineraries are defined by connection time, airline compatibility. Incheon International Airport (ICN) shows strong direct but weaker hub connectivity than peer hubs such as SIN, PVG, HND, and PEK. Applying terminal-specific Minimum Connecting Times significantly reduces feasible transfers at ICN, indicating strong sensitivity to terminal layout and passenger processing. A carrier realignment scenario reflecting the KE-OZ Merger substantially improves hub connectivity through increased same-terminal transfers. Results suggest that MCT assumptions matter more for hub performance than flight-supply expansion. Despite limitations from simplified terminal modeling and snapshot schedules, the study provides a transparent and replicable benchmark for operational connectivity assessment across Asian hubs.
