AOG stands for Aircraft on Ground and describes a situation where an aircraft cannot return to service until a technical fault has been resolved or a replacement component has been delivered. Every hour on the ground can disrupt flight schedules, passenger journeys, maintenance programmes and airline operations, making AOG logistics one of the most time-sensitive areas of freight forwarding. A successful AOG movement begins with accurate information, including the aircraft location, part number, dimensions, weight, collection readiness, customs status and required delivery deadline. The freight forwarder must then identify the fastest viable route, which may involve a dedicated vehicle, next-flight-out service, onboard courier, express airfreight or aircraft charter. The earliest departing flight is not always the fastest overall solution; airport cut-off times, cargo acceptance, aircraft capacity, transfer connections, customs opening hours and final-mile delivery must all be considered. Dangerous goods, export controls, security requirements and aircraft parts documentation must also be reviewed before movement, as urgency cannot override regulatory compliance. Effective AOG logistics requires coordination between airlines, MROs, suppliers, freight forwarders, customs brokers, ground handlers, carriers and delivery agents. Clear milestone communication is essential from collection and export clearance through departure, arrival, import clearance and final proof of delivery. Contingency planning is equally important because flight cancellations, missed connections, customs queries and capacity changes can quickly affect the original route. Aero Time Critical provides 24/7 coordination for urgent aircraft-part movements, combining route planning, proactive communication and controlled delivery across road, air, onboard courier and charter solutions. When an aircraft is grounded, the objective is not simply to move a package quickly—it is to select, manage and monitor the most reliable compliant route from collection to aircraft recovery.
