The fundamental difference between AOG and routine aircraft parts shipping lies in the complete reversal of normal logistics priorities. While routine shipping optimizes for cost efficiency and plans deliveries around convenient schedules, AOG logistics prioritizes speed and reliability regardless of cost, operating under the assumption that every hour of delay represents thousands of dollars in losses for the airline.

Routine aircraft parts shipping typically uses scheduled cargo flights that might operate once or twice weekly between specific cities, consolidated shipments to achieve better rates, and standard processing timeframes that can extend delivery times to several days or weeks. Airlines plan routine parts orders weeks or months in advance, coordinate deliveries with scheduled maintenance events, and optimize shipping costs by combining multiple parts into single shipments.

AOG shipping operates on entirely different principles, using whatever transportation method gets parts to their destination fastest, regardless of cost considerations. This might mean booking space on passenger flights that cost 10 times more than cargo flights, hiring dedicated couriers to hand-carry parts, or chartering private aircraft when commercial options aren’t fast enough. Every decision prioritizes time over money.

Processing procedures also differ dramatically between routine and AOG shipments. Routine shipments follow standard warehouse processes with normal picking, packing, and shipping schedules that might take 24-48 hours to complete. AOG shipments bypass normal queues, receive immediate processing by dedicated staff, and often have parts picked up within hours of the order being placed.

Communication protocols for AOG shipments involve continuous updates and immediate escalation procedures when problems arise. While routine shipments might generate automated status updates every few days, AOG shipments typically provide updates every few hours and include direct phone contact with logistics coordinators who can make real-time decisions to overcome obstacles.

Availability becomes another key differentiator, with AOG services operating 24/7 including weekends and holidays, while routine shipping typically follows business hours and standard working days. Airlines experiencing AOG situations don’t have the luxury of waiting until Monday morning or after holidays for parts to ship – the aircraft needs to return to service as quickly as possible regardless of what day it is.
