Who Actually Moves an AOG Part: Forwarder, Broker, Hand-Carry Courier or Dedicated Carrier
Short answer
Four kinds of company can move an AOG part, and they are not interchangeable. A freight forwarder buys space and consolidates. A broker sells capacity it does not own. A hand-carry courier flies with the part in the cabin. A dedicated expedited carrier puts one vehicle under one shipment. Which you want depends on custody, paperwork and who answers at 2 a.m.
When an aircraft is on ground, the first question is usually “how fast can it get here”. The one that decides the recovery is different: who is going to be holding the part. Speed follows from that. Comparing modes instead? That is in AOG Parts Delivery: Next Flight Out, Hand-Carry, or Dedicated Ground?.
What Is a Freight Forwarder in an AOG Situation?
A freight forwarder is a company that arranges transport by buying capacity from airlines and carriers and consolidating shipments, rather than operating the aircraft or truck itself.
Its strength is coverage: standing airline cargo relationships put a rotable into a hold on a route your own team would need a day to find. Its speed is bounded by the schedules it buys into — if the last suitable flight has departed, the forwarder does not have another flight, it has tomorrow. Consolidation also means terminal handling, where AOG shipments accumulate delay that never shows on a tracking screen.
Best fit: the window is a day or more, the routing crosses borders, and the paperwork is heavier than the clock.
What Does an AOG Broker Actually Do?
A broker is a licensed intermediary that arranges freight on carriers it does not own, taking a margin between what the shipper pays and what the carrier is paid.
Brokers matter because the recovery often needs a vehicle where nobody has a truck, and a good one finds it in ninety minutes. But what you contract for is a promise about a vehicle the broker will find: the driver has never met you, the equipment is unknown until it arrives, and the 2 a.m. escalation runs through a dispatcher covering forty other loads. If the first carrier falls through the broker re-covers the load — correct commercially, wrong when a custody-sensitive part is aboard.
Best fit: geography beats your carrier relationships and the part is not custody-sensitive.
What Is a Hand-Carry Courier and When Is It the Wrong Answer?
A hand-carry courier, also called an onboard courier, is a person who buys a passenger ticket and travels with the part as accompanied or cabin baggage, keeping physical custody for the whole journey.
It is the fastest option that exists for a small, light, high-value part on a route with frequent passenger service, and custody is perfect: one person holds it from pickup to handover, with no terminal and no handling queue.
The wrong-answer condition is regulatory, and it disqualifies hand-carry more often than people expect. Hazardous materials carried by a passenger are permitted only for the personal-effects items listed in 49 CFR 175.10 (eCFR, edition of 01.08.2026), and aircraft components are not among them. A part containing a lithium battery, a pressurised accumulator, residual hydraulic fluid, a pyrotechnic device or an oxidiser must move as declared, properly packaged cargo — which removes hand-carry entirely. A quote on a part that cannot legally be hand-carried is not a cheap option; it is a failed recovery found at a checkpoint.
What Does a Dedicated Expedited Carrier Give You That the Others Do Not?
A dedicated expedited carrier is an asset-based operator that assigns one vehicle and one driver to a single shipment, exclusive use, from pickup to delivery with no intermediate handling.
Three things follow from owning the asset. The vehicle does not stop for another load, so transit is a driving time and not a schedule. The driver is reachable, so custody is a name rather than a scan. And the carrier answers, because there is no one else to escalate to.
The trade-off is honest: over distance a truck loses to an aircraft, though the crossover sits closer than most assume once you add cut-offs, terminal dwell and the drive at both ends — the arithmetic is in AOG Freight: When Ground Is Actually Faster Than Air. Best fit: heavy, hazmat-classified or custody-critical, inside a day’s drive.
How Do the Four Compare Side by Side?
| Freight forwarder | Broker | Hand-carry courier | Dedicated carrier | |
|---|---|---|---|---|
| Owns the moving asset | No | No | No (buys a seat) | Yes |
| Who holds the part | Airline and terminal staff | An unknown contracted driver | One named courier, throughout | One named driver, throughout |
| Speed ceiling set by | Flight schedules and cut-offs | Time to find a truck | Passenger flight frequency | Driving time and hours of service |
| Handles hazmat / dangerous goods | Yes, as declared cargo | Depends on the carrier found | Usually disqualified under 49 CFR 175.10 | Yes, if the carrier is certified |
| Practical weight ceiling | Very high | High | Low (cabin or checked baggage) | High |
| Custody documentation | Airline handover records | Carrier-dependent | Continuous, one person | Continuous, one driver |
| Who answers at 2 a.m. | A branch office, in business hours | A dispatcher covering many loads | The courier, in the air or not at all | The carrier’s dispatch |
| Best fit | Cross-border, paperwork-heavy | Coverage gap in your network | Small, light, non-hazmat, frequent route | Heavy, hazmat, custody-critical, drivable |
How Should You Choose Between Them for a Specific Part?
Work down this list in order. It is deliberately not ordered by price.
- Classify the part first. Lithium cell, accumulator, residual fluid, pyrotechnic, oxidiser? If yes, hand-carry is out under 49 CFR 175.10 and you are choosing between declared air cargo and ground.
- Decide whether custody is auditable. If the receiving station is a 14 CFR Part 145 repair station and the part carries maintenance documentation under 14 CFR 43.9, the movement must produce a custody record that survives an audit, not a delivery scan.
- Measure the real window, not the stated one. Cut-off, terminal dwell and both drives count. A four-hour flight is rarely a four-hour recovery.
- Check who is accountable and when. Ask each provider, in writing, who is reachable at 03:00 and what happens if the first vehicle fails. The four types differ entirely in that answer.
- Then compare price. The option set is usually two by now, not four, and the comparison is finally meaningful.

Frequently Asked Questions
Who offers expedited freight for aerospace AOG parts?
Four provider types do: freight forwarders, brokers, hand-carry courier services and dedicated expedited carriers. Forwarders and brokers arrange capacity they do not own; couriers and dedicated carriers hold the part themselves. For hazmat-classified or custody-critical components, a dedicated carrier or declared air cargo is usually the only compliant route.
Is an aircraft parts freight forwarder the same as an expedited carrier?
No. A freight forwarder buys and consolidates space on aircraft and trucks it does not operate; an expedited carrier operates its own vehicle under exclusive use. The forwarder’s speed is bounded by flight schedules, the carrier’s by driving time.
How do you expedite engine parts to a grounded aircraft?
Classify the part for dangerous goods first, because that decides whether hand-carry is legal at all under 49 CFR 175.10. Then compare declared air cargo against dedicated ground on the real window including cut-offs and terminal dwell, and confirm the custody record the receiving Part 145 station will need.
How do you choose an expedited freight company for AOG work?
Ask four questions: do you own the vehicle, who physically holds the part, are you certified for the dangerous goods class of this component, and who answers at 03:00 if the first vehicle fails. Price comparison is only meaningful after those four.
Can any AOG part be hand-carried by a courier?
No. Under 49 CFR 175.10 a passenger may carry only the enumerated personal-effects items, and aircraft components are not among them. Parts with lithium batteries, pressurised accumulators, residual hydraulic fluid, pyrotechnics or oxidisers must move as declared, properly packaged cargo.
