Yes, you can smoke at Boeing Field / King County International Airport (BFI) — outdoors only, on the curb in front of the terminal. BFI is a small commercial terminal a few miles south of downtown Seattle, and the terminal building is smoke-free, so step outside to light up.
How Boeing Field Is Laid Out
BFI is owned and run by King County and is best known as Boeing’s flight-test base, a busy general-aviation field, and a cargo gateway. Scheduled passenger service is a small slice of operations: commuter carriers such as Kenmore Air run wheeled Kenmore Air Express flights to the San Juan Islands and Victoria, BC (its floatplanes fly from Lake Union, not Boeing Field), alongside other regional and charter operators. The passenger terminal is correspondingly small: a compact landside waiting area and a short walk out to the aircraft, without the long checkpoint queues of a major hub.
Where to Smoke at BFI
Smoke outdoors on the curb in front of the King County Airport terminal, away from the entrance doors and the small observation area. The terminal is compact, so there is no enclosed smoking shelter — the open curbside is where travellers light up while waiting for a flight or a ride. Under Washington law, stand at least 25 feet from doors, windows, and air-intake vents so smoke does not drift inside.
All smoking here is landside, at that curb: there is no indoor smoking lounge and nowhere to smoke once you have checked in and moved through to board. Because the terminal is tiny, stepping out for a cigarette and coming back costs only a few minutes; still give yourself a buffer before boarding.
E-Cigarettes and Vaping
Vaping and e-cigarettes follow the same rules as smoking under Washington law: not allowed inside the terminal, fine outdoors. Use the curbside area at least 25 feet from the doors rather than vaping indoors.
