Data Sources
Route & Traffic Data: BTS T-100 Domestic & International Segments. All US carriers + all international carriers. Monthly passengers, seats, departures by carrier and city pair. 2019-2026.
Source: Bureau of Transportation Statistics, transtats.bts.gov. Public domain, acquired programmatically via form-based download.
Airport Coordinates: OurAirports.com global database. 9,057 airports with IATA codes, lat/lon. All AS/QX/HA airports verified.
Carrier Codes: AS = Alaska Airlines (mainline), QX = Horizon Air (regional), HA = Hawaiian Airlines (merged into AS reporting Jan 2026). Domestic competitors: WN, AA, DL, UA, B6. Global: AC, AM, JL, KE, NH, QF.
Load Factor: Passengers / Seats from T-100 segment data, aggregated per selected date range. Color = 7-tier utilization (red <30% through violet >95%).
Hub Score: Weighted composite of route count (40%) and passenger volume (60%), normalized per carrier network.
Competitor Coverage: Full carrier networks shown (not filtered to Alaska overlap). Enables identification of indirect competition — e.g., Southwest BOI-LAS-SFO competing with Alaska BOI-SEA-SFO for the same Boise customer.
Visualization: Cesium.js 3D globe, CartoDB Voyager tiles, great circle arc interpolation. All browser-based, no server required.
