Airport orientation
Use this as the first-stop guide when the traveler knows the trip runs through Sea-Tac but still needs to sort out airport timing, terminal navigation, ground transportation, hotel shuttles, Link light rail, or the next Seattle planning page to use.
Core planning lane
SEA tells domestic travelers to arrive two hours before departure and international travelers three hours before departure. It also flags the busiest drive and checkpoint periods before 9 a.m., from 2 to 5 p.m., and from 9 to 11 p.m.
Core planning lane
SEA publishes terminal maps, printable directories, and checkpoint details. One helpful rule: all gates are accessible from any checkpoint, so the best checkpoint is often the shortest one rather than the one closest to your airline sign.
Core planning lane
Ride-share and taxis pick up on the third floor of the parking garage. Hotel courtesy shuttles use Islands 1 and 2 on that same level. Link light rail uses SeaTac/Airport Station, which connects to the terminal area by a pedestrian bridge.
How to use this guide
Use this page before booking when the traveler still needs to decide how early to arrive, where to meet a ride, whether a hotel shuttle makes sense, or which next planning page should guide the trip.
SEA notes that all gates are reachable from any checkpoint. That changes the usual first-timer instinct: the best checkpoint is often the one with the better line, not the one nearest the airline counter.
After the airport basics are clear, move into the page that matches the real destination: airport hotels, downtown Seattle, Bellevue and the Eastside, cruise terminals, parking, arrivals, or departures.
