An onboard courier (OBC) is a person who travels with your shipment, usually as a passenger on a commercial flight, and hand-carries it from the pickup address to the person who signs for it. Because the shipment never sits in a cargo hold, a warehouse, or a sorting facility, an onboard courier is the most direct and traceable way to move a small, critical item over a long distance.
How an Onboard Courier Job Runs, Step by Step
No two OBC jobs are identical, but most follow the same sequence. Knowing it helps you give the right information at booking and shows you where the time actually goes.
- Booking and flight selection. You supply the origin, destination, ready time, and deadline. Dispatch checks which commercial flights can meet it and books the courier onto one. From this point the flight schedule, not the speed limit, sets the clock.
- Pickup. The courier collects the item and its paperwork, checks the packaging, and records the handover.
- Airport and screening. Depending on its size, weight, and contents, the item travels in the cabin or as checked baggage under the courier's name. Airline and security rules decide which, and some contents cannot fly at all.
- The flight. The shipment stays with the courier. There is no cargo cut-off to beat, no transfer on the tarmac, and no waiting for freight to be broken down at the destination airport.
- Arrival and, if needed, customs. On international trips the courier carries the commercial paperwork and takes the shipment through border formalities in person.
- Hand-off. A final ground leg takes the item to the recipient, who signs. The courier's record from pickup to signature is the proof of delivery.
Onboard Courier, Next Flight Out, or Air Cargo?
These three options are often confused, yet they work differently, and the difference is mostly about who has the shipment in their hands.
| Onboard courier (OBC) | Next flight out (NFO) | Standard air cargo | |
|---|---|---|---|
| Who moves it | A person who accompanies it | Airline cargo staff, booked on the next available flight | Airline cargo staff, on a scheduled booking |
| Who holds it in transit | The courier, at all times | Cargo handlers at each airport | Cargo handlers at each airport |
| Airport work for you | None, the service is door to door | Drop-off at the cargo terminal and a pickup at the other end | Drop-off and pickup, with longer handling times |
| What sets the speed | Flight times and courier availability | Flight times, cargo cut-offs, and breakdown time on arrival | The service level booked |
| Best suited to | Small, critical, or irreplaceable items | Urgent freight too large for one person | Planned shipments and larger volumes |
A next-flight-out booking is still handled freight: it is subject to acceptance cut-offs at departure and to the time it takes to locate and release the cargo on arrival. For distances a van can cover in a day, a dedicated ground run is usually simpler and cheaper. Onboard courier earns its place when the route is too long to drive in time.
What Gets Sent by Onboard Courier
- Aircraft components in an AOG situation. When an aircraft is grounded, the part's price is measured against what each hour on the ground costs. See our explanation of AOG shipping.
- Original documents that cannot be reissued, such as signed originals bound for a court or a foreign registry. Our guide to original documents by courier covers how they are prepared.
- Time-limited medical or laboratory items on routes too long for ground transport, where the handling record must be complete from door to door.
- One-off prototypes, samples, and tooling that cannot be replaced if lost.
- Any shipment where one named person should be accountable for it from the pickup address to the recipient's hands.
Limits: What an Onboard Courier Cannot Do
- Size and weight. A courier can carry what one person can reasonably take on a flight within airline allowances. Pallets and heavy crates belong on cargo, ideally with a planned airport cargo pickup at Montréal-Trudeau.
- Dangerous goods. Batteries, dry ice, and some chemicals are regulated regardless of how they travel. Some, such as lithium batteries beyond airline limits, cannot be carried this way at all. Read our dangerous goods basics before you book.
- Entry rules. A courier travelling internationally must meet passport and visa requirements, and the destination country decides what may be brought in commercially.
- Seat and schedule availability. Quiet routes offer fewer flights, so a connection or a next-day departure may be the realistic option.
- Customs. Goods enter as a commercial importation, not as personal baggage, and need the right paperwork. See our overview of cross-border courier shipping.
Why It Costs More, and When It Is Still the Cheaper Option
An onboard courier price reflects an airline ticket and a person's time at both ends, so per kilogram it is expensive. The comparison that matters is not with freight but with the cost of the delay: a grounded aircraft, a missed filing, a spoiled batch, a postponed procedure. When one lost day costs more than the premium, the premium is the economical choice. When it does not, a ground run or standard freight serves you better. Our guide to what drives courier pricing shows how any courier quote is built.
Before You Book: A Short Checklist
- Exact pickup and delivery addresses, and the latest acceptable arrival time.
- Dimensions, weight, and number of pieces, and how the item is packed.
- A plain description of the contents, including any batteries, liquids, or temperature limits.
- The paperwork the recipient or border authorities will expect, such as a commercial invoice, a release certificate, or a requisition.
- The name and a reachable phone number of the person who will sign at the destination.
- A fallback plan in case the planned flight is cancelled or delayed.
Frequently Asked Questions
Is an onboard courier the same as a freight forwarder?
No. A freight forwarder arranges cargo moves with airlines and carriers, and the goods travel as freight with nobody accompanying them. An onboard courier physically accompanies the shipment and hands it directly to the recipient.
How fast can an onboard courier deliver internationally?
As fast as flights and border formalities allow. Many routes can be covered in about a day, door to door, when a suitable flight exists, while thinner routes may need a connection or a next-day departure. Dispatch can tell you quickly what is realistic for a specific route.
Can an onboard courier carry dangerous goods?
Only if the goods are correctly classified, packed, marked, and documented, the airline accepts them, and the person carrying them is trained. Some items cannot be carried this way at all, so always declare the contents when you book. See our guide to dangerous goods by courier.
What size of shipment can go by onboard courier?
Roughly what one person can carry within airline baggage allowances, such as a case, a toolbox, or a small component. Larger or heavier items go by air cargo, which can be paired with a pickup at the airport.
Do I need special documents for an international hand-carry shipment?
Usually yes. Expect a commercial invoice describing the goods and their value, plus any certificates the goods require, such as a release certificate for an aircraft part. Requirements vary by destination, so confirm them when you book.
Choosing Between Hand-Carry and Cargo
The choice comes down to one question: what does a missed deadline cost, and who needs to be able to account for the shipment at every step? If the answer is "a great deal, and one named person," hand-carry is worth pricing. If the shipment is large or the deadline is measured in days, cargo or a ground run will serve you better.
