Aircraft Disinsection at St. Louis Downtown Airport (CPS)
St. Louis Downtown sits on the Illinois bank of the Mississippi with the Arch filling its windscreens, and its hangars hold Jet Aviation’s St. Louis completions and maintenance center. Departures from CPS bound for countries that mandate disinsection get treated before the cabin closes.
If your next departure from CPS 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. CPS sits in our central response region: typically same day to next morning, within 24 hours of confirmation.
About St. Louis Downtown Airport
With a 7,002-ft main runway and a location closer to downtown St. Louis than Lambert, the field pairs corporate convenience with serious industrial capability. Jet Aviation’s campus handles interiors, maintenance, and refurbishments for large-cabin jets, work that draws international tails to Cahokia. When those aircraft redeliver to owners in Europe or beyond, the ferry leg starts here. The disinsection certificate can be in the flight bag before engine start.
Where the requirement comes from
Whatever the destination, the mechanism is the same: the arriving country requires the aircraft to have been disinsected, and pre-embarkation treatment at the last port before that country, performed on the empty aircraft, is a method it accepts. For a non-stop flight out of CPS, that last port is CPS.
Departures from CPS 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 St. Louis Downtown Airport makes CPS the last port before the destination, which is exactly where pre-embarkation treatment belongs.
How it works on the CPS ramp
Once the plan is set we work directly with the CPS FBO and your crew on access, ramp position and timing. Our technician arrives before the agreed slot, confirms the aircraft is empty with catering and cleaning done, and applies the WHO pre-embarkation treatment through the cabin, flight deck and holds. After the specified rest and ventilation the aircraft is released for boarding, certificate in hand.
