About Spirit of St. Louis Airport
Spirit of St. Louis in Chesterfield is the St. Louis region’s primary business aviation airport, home to a large corporate fleet west of the city and well equipped for large-cabin aircraft. International departures leave from SUS throughout the year.
Where the requirement comes from
The rule is set by the arriving country, not by the airport you leave from. If your destination requires disinsection, the aircraft must be treated at the last port before that country, and for a non-stop departure from Chesterfield that port is SUS. Pre-embarkation treatment of the empty aircraft here is a method those countries accept.
Departures from SUS that trigger a disinsection requirement are mostly transatlantic. Italy is the one that catches operators most often, because it applies to aircraft arriving from the United States; Greece joined the list in September 2025, and Greece, Jamaica, India, Egypt follow. A non-stop crossing from Spirit of St. Louis Airport makes SUS the last port before the destination, which is exactly where pre-embarkation treatment belongs.
How it works on the SUS ramp
We coordinate with your FBO and crew, 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 flight documents. Passengers arrive to a treated aircraft.
