Where it sits

47.4°N, 122.3°W puts SEA in the northern hemisphere, 5,276 km from the equator and 4,732 km from the North pole.

Where these facts come from

The profile is looked up, not written from memory: type, runways, elevation and the official website from OurAirports (public domain); opening year, namesake, operator and passenger count from Wikidata (CC0); the city centre from GeoNames (CC BY 4.0). Where a source has nothing, the line is left out. Distances, neighbours and the antipode are computed from the coordinates.

What you won’t find: terminal maps, airline lists, shops or live departures. Orbit is a logbook, not a flight tracker, and a page that guessed at those would be worse than one that leaves them out.
