Aircraft Disinsection at Seattle-Tacoma International Airport (SEA)
Seattle-Tacoma International is the Pacific Northwest’s long-haul gateway and hosts long-range business aviation departures. Pacific private flights leave from SEA year-round.
If your next departure from SEA is to a country that requires disinsection, we come to your aircraft here, treat it empty before boarding to the WHO pre-embarkation method, and issue the certificate for the flight. We ask for 36 to 48 hours of notice at SEA, and scheduled bookings are guaranteed for the departure.
About Seattle-Tacoma International Airport
Seattle-Tacoma International is the Pacific Northwest’s long-haul gateway and hosts long-range business aviation departures when the aircraft needs its runways or customs infrastructure. Pacific private flights leave from SEA year-round.
Where the aircraft disinsection requirement comes from
Think of it from the arrival end: the destination expects a treated aircraft and a certificate. Pre-embarkation gives it both, provided the treatment happens at the last port before that country. Non-stop from SEA, that is SEA; with a stop en route, the plan changes and we tell you how.
From SEA the requirement is mostly a Pacific one: Australia and New Zealand require disinsection on every arriving international aircraft, and the Cook Islands, Fiji and the Solomon Islands require it too. Many itineraries from Seattle stop in Hawaii, which then becomes the last US port and the place for pre-embarkation treatment; non-stop departures are treated here at SEA. Australia, New Zealand, Chile appear on the list as well.
The aircraft disinsection process on the SEA ramp
We coordinate with your FBO and crew at SEA, arrive ahead of the agreed time, and treat the aircraft where it is parked once catering and cleaning are complete and the cabin is empty. Cabin, flight deck and holds are treated to the WHO method, the aircraft is ventilated and released for boarding after the required wait, and the certificate goes aboard with the Seattle flight documents. Passengers arrive to a treated aircraft.
