SeaTac Airport Firearm Possession

Possession of a firearm at SeaTac Airport is made unlawful by RCW 9.41.300. RCW 9.41.300(1)(e) states that it is unlawful to possess a weapon in the “restricted access areas” of a commercial airport, including passenger screening checkpoints at or beyond the point at which a passenger initiates the screening process.

However, these areas do not include airport drives, general parking areas and walkways, and shops and areas of the terminal that are outside the screening checkpoints and that are normally open to unscreened passengers or visitors to the airport.

Attempting to take a firearm through SeaTac airport security will result in you being detained by SeaTac police. Your firearm will be seized, and the police will refer charges to the King County Prosecutor for possessing a weapon in a prohibited place. 

Possessing a weapon or firearm at SeaTac Airport is a gross misdemeanor, punishable by a maximum of 364 days in jail and a $5,000 fine. You may also have to forfeit your firearm.

With a proper defense provided by an experienced gun rights lawyer, you may be able to avoid most of the negative consequences of possessing a firearm in a prohibited place.
