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.
Of the 661 airports on this site it is the 88th most northerly, which makes it the 574th most southerly.
Straight through the middle
Straight down through the centre of the Earth comes out at 47.4°S, 57.7°E. The nearest airport on this site to that point is Roland Garros (RUN) in Réunion, still 2,960 km away — most of the planet's antipodes are ocean.
What’s near it
The closest other airport on this site is Victoria (YYJ), 157 km away in a straight line. Nothing else on this site is within 100 km.
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.
