DELIVERY
Table of Contents
AOG stands for aircraft on ground. It is the status an operator assigns when a fault stops an aircraft from flying and it cannot be released until a specific part or repair arrives.
The phrase exists because the situation needs its own vocabulary. An AOG is not a delay to be managed. It is a stopped asset, and everything about how the part moves changes the moment the status is called.
Why AOG Is Treated Differently
A parked aircraft costs money in several directions at once.
There is lost revenue from the flights it will not operate, the cost of rebooking or compensating passengers, crew that has to be repositioned or paid to wait, and knock-on delays across the rest of the schedule as the day unwinds.
Estimates vary widely by aircraft and operator, but the figure is commonly put in the thousands of dollars per hour for a commercial airliner. Against that, the cost of moving one part quickly stops being the number anyone is optimizing.
That is the whole logic of AOG logistics. Speed is the requirement, and price is whatever speed costs.
The Ways an AOG Part Actually Moves
Four methods cover most AOG movements, in rough order of speed and cost.
- Ground expedite, or hot shot. A dedicated vehicle drives the part directly, with no other stops. Best inside a few hundred miles, and the simplest to arrange because nothing is handed to a third party.
- Next Flight Out. The part is driven to the airport and tendered to the next departing flight with capacity, then collected at the other end. Fast over distance, and dependent on the flight schedule.
- Hand carry. A courier travels with the part as accompanied baggage. Used for items that cannot be tendered as cargo or when custody must be unbroken.
- Charter. A dedicated aircraft. Reserved for cases where the AOG cost per hour exceeds the charter cost, which happens more often than people expect.
The right choice is usually decided by the distance and by the next departure time, not by preference.
What Drives the Cost
AOG quotes look unpredictable until you see what is being priced.
- Distance and vehicle. A dedicated van driving 200 miles is priced differently from a sedan crossing a metro area.
- Time of day. AOG calls do not respect business hours, and after-hours dispatch carries a premium.
- Airside access. Delivering to a hangar or to the ramp needs credentials and an escort arranged by the operator.
- Part characteristics. Size, weight, and whether the item is classed as dangerous goods, which changes what may be flown and by whom.
- Waiting time. Time spent held at a counter, a gate, or a receiving dock is billed separately.
What to Have Ready When You Call
An AOG call goes faster when the details arrive with it.
- The collection address and a contact who is physically there now
- The delivery address, and whether it is landside or airside
- Part dimensions and weight, and whether it is on a pallet or loose
- Whether the item carries a dangerous goods classification
- The tail number or work order reference
- The time the aircraft is scheduled to be released
That last one matters most. A release time lets a dispatcher work backward and tell you honestly whether a deadline is reachable, instead of starting a run that was never going to make it.
AOG in Southern California
Los Angeles is an unusually good place to have an AOG, which is not something you can say about most regions.
Six airports sit inside a short drive of each other: Los Angeles International, Hollywood Burbank, Van Nuys, Long Beach, John Wayne, and Ontario. Van Nuys is worth knowing about, because it handles the general aviation and charter traffic that AOG parts frequently move on.
The supplier base is close too. El Segundo, Hawthorne, Torrance, Long Beach, and the San Fernando Valley hold a dense cluster of aerospace manufacturers, machine shops, and MRO operations.
In practice that means a part is often already in the region. The job is moving it across a metro area at the wrong time of day, which is a dispatch problem rather than a freight problem.
Frequently Asked Questions
What does AOG mean in aviation?
AOG means aircraft on ground. It is the status used when a technical fault prevents an aircraft from flying and it cannot return to service until a specific part or repair is completed. The term signals the highest level of urgency in aviation maintenance, and it changes how parts are sourced, routed, and delivered, because the aircraft is generating cost for every hour it stays parked.
What is AOG logistics?
AOG logistics is the specialized transport of parts and components to an aircraft that has been grounded. It covers sourcing the fastest available routing, moving the part by dedicated vehicle or by air, coordinating airside delivery where required, and tracking custody throughout. It differs from standard freight in that the schedule is set by the aircraft’s release time rather than by a service level.
How fast can an AOG part be delivered?
AOG parts move as fast as the geography allows. Within a metro area a dedicated vehicle can collect within the hour and drive direct. Over longer distances, the limit is the next departing flight with capacity, so the realistic answer depends on the airport pair and the time of day. A dispatcher working backward from your release time can tell you what is achievable before anything is committed.
What is the difference between AOG and hot shot?
AOG describes the situation, and hot shot describes one way of solving it. Hot shot is a dedicated ground expedite, where a vehicle carries the load directly with no other pickups. An AOG part might move by hot shot, by Next Flight Out, by hand carry, or by charter, and the method is chosen by distance and deadline rather than by the AOG status itself.
Getting a Grounded Aircraft Moving
Worldline Express runs AOG and expedited parts delivery across Los Angeles and Orange County, with Next Flight Out for anything beyond the region.
Our aerospace and manufacturing logistics service covers dedicated ground expedite, airport tendering, and delivery to hangars where the operator has arranged access for us.
