Where the aircraft disinsection requirement comes from
GEG is where the requirement is satisfied for a non-stop flight, because pre-embarkation treatment belongs at the last port before the destination country. The arriving authority requires the aircraft to have been disinsected; treating it empty here, before boarding, meets that requirement for the countries that accept the method.
From GEG 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 Spokane stop in Hawaii, which then becomes the last US port and the place for pre-embarkation treatment; non-stop departures are treated here at GEG. Australia, New Zealand, Chile appear on the list as well.
The aircraft disinsection process on the GEG ramp
We coordinate with your FBO and crew at GEG, 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 Spokane flight documents. Passengers arrive to a treated aircraft.
