On-board courier: the fastest legal way to move a small part.

One vetted person carries your shipment as accompanied baggage on the next scheduled flight — through passenger channels, never out of sight, signed for at the other end.

What it is

A passenger, a seat, and your part in the cabin.

Nothing is consolidated, nothing waits in a warehouse, and no forklift touches it. That is the whole method — and it is why it is fast. It is used when the deadline is measured in hours rather than days, and it stops being the right answer the moment the piece outgrows one person's baggage.

What travels

Small, expensive to be without, needed at a named hour.

Who sends it

What actually travels in a courier's bag.

The industries that call the desk most often, and the items they send.

Documents that must be originals
Executed contracts with wet signatures, certificates and licences, tender files, customs and trade originals — when the sender insists on one named pair of hands. Routine document shipments move faster and cheaper as air freight.
Automotive
ECUs and control units, sensors, PCBs, wiring harnesses, injector parts, prototypes, single-batch components.
Airlines, MRO, AOG
Avionics modules, sensors, valves, control units, line-replaceable parts, tooling.
Machinery & plant
PLCs, servo motors, inverters, boards, bearings, valves, pump and CNC parts, robot spares.
Electronics & semiconductor
Chips and wafers, photomasks and reticles, processors, server and telecom modules, prototypes.
Medical & life sciences
Devices, diagnostic and laboratory equipment, spares, and compliant clinical shipments in validated packaging.
Data, broadcast & media
Encrypted drives, rushes and masters, camera bodies and lenses, broadcast modules.
Fine art & high value
Works on canvas and paper, small sculpture, watches, jewellery and stones, garment samples before a show.

Freight forwarders use this desk under their own name too. Whether a specific shipment can travel is decided case by case — commodity, declared value, the customs regime at both ends, airline rules and insurance terms all have a say. Cultural property and permit-controlled goods only once the permits are in hand.

Where it goes

The corridor an OBC actually covers.

A courier flies where passengers fly, so the reach is the scheduled network — not a fleet. Our most-worked sectors from Istanbul, with the flying time only.

SectorIn the airSame day realistic?
Istanbul → Milan≈ 3 h 05Yes, on a morning departure
Istanbul → Geneva≈ 3 h 30Yes, on a morning departure
Istanbul → Frankfurt≈ 3 h 05Yes, several departures daily
Istanbul → London≈ 4 h 05Usually, if collection is before noon
Istanbul → Dubai≈ 4 h 45Often, overnight arrival typical
Beyond the corridorConnection dependentThe desk works it back from your deadline

Flying time only. The door-to-door figure depends on where the part sits now, how far the receiving point is from the airport, and which channel customs sends it through — so the desk asks for your hour and works backwards.

How a mission runs

Istanbul to Frankfurt, hour by hour.

A worked example, not a past job dressed up as a case study — so you can see where the hours go and which of them are yours to shorten. There is no tracking map; there is a named coordinator and a message every time something changes.

08:12Request reaches the desk: one box, 6 kg, a control unit, needed on a bench in Frankfurt before the night shift.
09:40Options back to you — the departures that make the deadline, the courier who can reach your gate, the customs route.
10:05You confirm. The ticket is issued and the export declaration lodged while the courier is still on the road.
11:50Collection at your factory. Photograph and signed receipt reach you from the doorstep.
13:30Check-in at Istanbul, and a message when the courier is airside.
15:05Departure. Roughly three hours in the air.
17:10Landing at Frankfurt. Import clearance in the passenger channel, invoice in hand.
18:45Handover against signature at the plant. Time and signature to you in writing; the file closes.

Two of those lines move. If your paperwork is ready when you call, the gap between 08:12 and 10:05 shrinks to minutes; if the receiving site is two hours from the airport rather than forty minutes, the last line moves the other way.

Who carries it

A stranger is holding your part.

  • Identity and right to travel — passport checked against the person, visas verified for that exact route and date.
  • Criminal record certificate — requested before a first mission. No certificate, no mission.
  • Briefed per mission — what the item is, what it is worth, what customs will ask.
  • Signature at both ends — the chain of custody is a document, not a promise.

Limits

What we will not do.

  • Undeclared goods — hand-carry is a speed technique, not a customs bypass.
  • Most dangerous goods — lithium cells above threshold, aerosols, flammables. Declare contents; the desk validates first.
  • Cash and bearer instruments — not carried, on any route, at any price.
  • Beyond one person's bag — above ~30 kg the honest answer is a freighter or a charter, and we say so.

Questions

What clients ask.

How does customs work for a hand-carried commercial part?

It is declared — properly. Depending on route and value, the courier clears through the red channel with a commercial invoice, or the desk prepares formal export/import entries in advance.

Who pays the duty and import taxes?

Normally the receiver, unless you and the sender agree otherwise before departure. What a hand-carry changes is the timing, not the liability: the assessment happens at the counter, in front of the courier, rather than days later in a warehouse. The amount depends on how the goods are declared — commercial consignment, temporary import for a repair or exhibition, or personal effects — and on the destination's own thresholds. We tell you which regime applies before the courier is booked. We do not guess a figure on a web page.

Can dangerous goods travel OBC?

Mostly no: passenger-aircraft rules are strict, and lithium batteries above thresholds, liquids and aerosols are frequent blockers. Declare the exact contents; the desk validates before a courier is booked.

Can you take it if it is very valuable?

Often, and that is much of the work — but value changes the questions. Declared value drives the customs channel, the insurance terms and sometimes whether an airline will accept it in the cabin. Tell the desk the real figure at the start rather than at the airport.

Can a private person use this, or is it only for companies?

Both, though most missions are commercial. If something of yours is stuck in another country the method is identical; what changes is the customs side, because without a commercial invoice personal effects are declared differently and duty may apply on arrival.

Can someone accompany my pet on a flight?

Yes — a small cat or dog can travel in the cabin with a passenger on most airlines, larger animals in the hold on the same flight. But this is animal transport, not a courier job, and the paperwork decides it: microchip, rabies vaccination and often a titre test, a veterinary health certificate valid for the travel window, an IATA-compliant carrier, the destination's import rules, and an airline that accepts that species and size on that route and date. Some of it takes weeks, not hours.

What if the part is too big for a courier?

Then we say so on the first call. Above one person's baggage the comparison moves to next-flight-out freight or a charter, and the desk prices whichever actually makes your deadline.

A part that fits a bag and a deadline that doesn't wait?
