AOG Logistics: How an Aircraft-on-Ground Shipment Actually Moves
An aircraft-on-ground event is not a freight problem, it is a deadline problem with a freight component. The cost of the aircraft sitting dwarfs every transportation decision on the file, which changes how the shipment should be planned. This guide sets out how an AOG movement is scoped, what a coordinator needs from you in the first five minutes, and the failure points that turn a four-hour recovery into an overnight one.
For maintenance control, purchasing and stores teams scoping an AOG move.
Start with the deadline, not the shipment
Standard freight planning starts with the cargo and works toward a transit time. AOG planning runs in reverse: you fix the required on-wing or on-dock time, subtract the receiving station's access constraints, subtract the final-mile drive, subtract terminal recovery, and whatever is left is your usable booking window. That number decides the mode, not the other way around.
The practical consequence is that a slower-looking option often wins. A direct-drive ground unit leaving in forty minutes routinely beats a flight that leaves in three hours and lands at a terminal that closes before recovery.
The intake set that prevents rework
Most delay on an AOG file is caused by information arriving in pieces. Provide these together and the plan can be committed on the first pass:
- Tail number, aircraft type and the AOG station
- Part number, serial and your internal reference
- Origin address and destination station, including cargo terminal and access hours
- Ready time, hard cut-off and required delivery, each with the local time zone
- Pieces, weight, dimensions and dangerous-goods classification status
- Two escalation contacts reachable around the clock
- Whether the part is rotable, and whether a core return needs to be booked on the same file
How the mode gets selected
Mode selection on an AOG is a comparison of committed arrival times, not published transit times. A coordinator will typically evaluate next-flight-out on commercial cargo capacity, a dedicated ground unit or team, and a hand-carry or on-board courier where the part is small and the lane is short on flight options.
Each option carries a different failure risk. Commercial air introduces screening, terminal acceptance and offload risk. Dedicated ground introduces hours-of-service and weather risk. The right answer is the option whose failure modes you can absorb given the deadline.
Where AOG shipments actually fail
In practice, the recurring failure points are unglamorous:
- Dangerous goods discovered at the terminal rather than declared at intake
- Known-shipper or screening status not confirmed before the tender
- Recovery booked without checking the destination terminal's closing time
- Receiving station access hours or airside escort requirements not verified
- A single point of contact who goes offline mid-shipment with no escalation path
- Cross-border paperwork prepared after dispatch rather than before
What good communication looks like
A well-run AOG file produces timestamped events, not a tracking link: pickup confirmed, tendered, flight departed, recovered, out for delivery, delivered with POD. Each event goes to the named stakeholders you specify, and every exception comes with a revised plan rather than just a notification.
Ask for that structure explicitly when you place the order. It is the single clearest indicator of whether the file is being coordinated or merely dispatched.
Questions we get on this
- What does AOG stand for in logistics?
- AOG means aircraft on ground: an aircraft is out of service until a specific part, tool or component arrives. In logistics it signals a shipment where the deadline governs every other decision.
- Is next flight out always the fastest option for AOG?
- No. Next flight out is fastest on long lanes with frequent cargo capacity. On regional lanes, or when the destination terminal closes before recovery, a dedicated ground unit frequently delivers sooner.
- Who is responsible for dangerous goods classification?
- The shipper. Classification, packaging, marking and documentation remain the shipper's legal responsibility; a broker coordinates carriers qualified to accept the correctly documented cargo.
Have a shipment that cannot wait?
Send the mission details and a coordinator will respond with a plan, constraints and the reference number for your file.
