Onboard Courier

An onboard courier, often called an OBC or hand carry courier, is a person who travels on a commercial passenger flight with a shipment and delivers it by hand. The shipment travels as the courier's checked or carry-on baggage instead of as airline cargo, so it is never left in a cargo warehouse or sorting facility. Onboard couriers are used for small, urgent and valuable items, such as aircraft parts, production parts, medical samples and legal documents, when the item must arrive quickly and stay in a person's care.

The shipper books the service, and the provider finds the next suitable flight and a courier. The courier, or a driver working with them, collects the item and signs for it. At the airport, the courier checks in and passes through security screening with the shipment, then flies with it and stays with it through any connection. After landing, the courier collects any checked bags and travels directly to the receiver to hand over the item. The shipper receives updates along the way and proof of delivery at the end.

An onboard courier can carry items that fit within airline baggage rules for size, weight and number of bags. Common shipments include aircraft and machine parts, electronic components, prototypes, medical samples and supplies, legal and confidential documents, and high-value goods. Dangerous goods, such as lithium batteries and some chemicals, are restricted and may be limited or not allowed. Large crates, pallets and very heavy pieces usually cannot be hand carried and are better moved as air cargo or by charter.

The cost of an onboard courier depends mainly on the courier's airfare, which is often high for last-minute bookings on the next suitable flight. The courier's time and return trip, fees for extra or overweight bags, the ground transport to and from the airports, the distance and the number of connections also affect the price. International trips may add customs and documentation costs. Hand carry usually costs more than shipping as cargo, but for critical items it can cost far less than the delay it prevents.

Yes. Airlines carry packages and freight as air cargo without a courier on board. The shipment is delivered to the airline's cargo facility, screened, and loaded on a flight, then collected at the destination airport. Services such as next flight out use this method for urgent freight. The difference is that the shipment is handled by airline and airport staff rather than staying in one person's care, and it must meet the airline's cargo cutoff. For larger items, sending as air cargo is usually cheaper than hand carry.

With hand carry, a courier flies with the shipment as baggage and delivers it by hand, so it never leaves their care. With next flight out, the shipment is tendered to the airline as cargo and placed on the first suitable flight, with drivers delivering it to the departure airport and collecting it at the arrival airport. Next flight out can carry larger items such as pallets and usually costs less, while hand carry offers closer custody and avoids cargo cutoffs and warehouse handling.

Onboard courier shipments are usually tracked through updates from the courier and the provider at key points: when the item is collected, when the flight departs, when it lands, and when it is delivered. Some providers also share flight tracking or photos. Each handoff is recorded, and at delivery the receiver signs, creating a proof of delivery with the time and the name of the person who signed. This record shows the shipment's chain of custody from pickup to delivery, which matters for valuable and sensitive items.

Yes. Onboard couriers can carry shipments across borders, including from the United States to Canada and Mexico. Because the shipment enters another country, it must be declared to customs on arrival, and the courier presents it with the documents the shipper provides, such as a commercial invoice and any permits the goods need. Duties or taxes may apply. Incomplete paperwork can hold the shipment at the border, so shippers should prepare the documents before the courier departs and confirm requirements for the goods.

Items that cannot be hand carried include anything too large or heavy to travel as airline baggage, such as pallets, large crates and heavy machinery. Many dangerous goods are restricted or forbidden as baggage, including some flammable liquids and gases, certain chemicals and explosives, and lithium batteries above set limits. Illegal items and goods that need special permits the courier cannot obtain are also excluded. Rules differ by airline and country, so shippers should describe the item fully when booking and confirm it can travel.

To book an onboard courier, contact a provider by phone or quote form with the details of the shipment. Give what the item is, its size and weight, whether it contains batteries or other regulated contents, the pickup and delivery addresses, contacts at each end and when it must arrive. For cross-border trips, have the customs documents ready. The provider books the next suitable flight and a courier, confirms the plan and pickup time, and sends updates until the item is delivered and signed for.
