Not sure how your company operates. Usually you do carry documentation of the cargo on board (Cargo Manifest, Airway Bills, etc). Aslo, if all of the sudden you start going to new destinations, it should bring up some flags. As far as Amerijet destinations, they include: The Carribbean (Most Islands), Mexico (MEX/MID/CUN), Central America (BZE, SAL, SAP, GUA), South America (Venezuela:MAR/PRG/PMV/BLA/MIQ, Guyana:GEO), Haiti, Jamaica, Domenican Republic (SDQ/STI/POP), Trinidad. Another clue would be a noticable increase in freight, specially given the trend for the last 8 months. Also, if you start seeing Amerijet trucks show up at your facility to drop off freight.
