Air cargo: what changes versus road

It travels faster and stops for different reasons: here what delays you is not traffic, it is security and paperwork.

Updated on 13/08/2026

The first air shipment surprises nearly everyone: the flight takes four hours and the goods take four days. It is not the plane — it is everything that happens before it boards, and it runs on rules that road transport simply does not have.

Important

The first row decides your lead times and almost nobody knows it before their first shipment: **if your company is not accredited within the air cargo security chain, every shipment goes through physical screening**. That adds time, cost and sometimes means opening the packaging you prepared so carefully. Accreditation is applied for, takes its own process and cannot be improvised for Thursday's shipment — but it changes the whole operation for anyone shipping regularly.

What to have ready before booking

  1. 1

    A real description of the goods, not a commercial one

    «Samples» is not a description and generates the most queries.

  2. 2

    Weight and dimensions of the packed unit

    The charge comes from there, and a wrong measurement is corrected late.

  3. 3

    Knowing whether it contains anything restricted

    Batteries, aerosols, liquids: the whole procedure changes.

  4. 4

    And commercial documentation consistent with itself

    Invoice, packing list and your declaration must say the same.

Watch out

What really holds shipments up is not customs: it is **something inside that nobody declared**. A device with a lithium battery, a spray can inside a box of spares, a sample containing alcohol. Whoever packs it does not think of it as dangerous because they handle it daily, and by air it has its own treatment. Asking «does this contain batteries, liquids or gases?» before packing avoids half the incidents.

Who you talk to for what

Worth knowing

Which roles exist in the air cargo security chain, what each requires and which goods are restricted are governed by specific aviation rules and vary by country and airline. **Your forwarder or adviser settles that**; here we explain why air freight behaves differently and what is worth resolving beforehand.

Is accreditation worth it?

If you ship often, almost always: it saves on every shipment.

Can I send anything by air?

No, and what you cannot varies. Ask before packing.

Why am I charged more weight than it weighs?

Because volume counts when it is greater; measuring properly avoids surprises.
