Learn how chargeable weight is calculated, what an AWB or Bill of Lading actually does, how Incoterms shift responsibility, and where delays usually happen at terminals and depots.

Air freight rarely fails because the base rate is high. It fails because the quote looks simple, then the invoice arrives with add-ons: handling, screening, waiting time, rework, storage, and rebooking. If you don’t know what’s usually included, you can’t compare quotes fairly.
For the full air freight process (airports, documents, delays, and planning), read: Air Freight in Australia: How It Works, What It Costs, and How to Avoid Delays . This page focuses only on costs: what you typically pay for, what gets added later, and how to avoid surprise charges.
Many air freight quotes are priced on chargeable weight, which is usually the higher of actual weight or volumetric weight. If you’re new to that concept, read: chargeable weight in air freight explained .
What’s included depends on the provider and service level, but most quotes contain a combination of:
The problem: many quotes show only the linehaul, then add the rest later as “local charges.”
These are the cost buckets that frequently appear after the headline rate:
If you want the operational view (not just the fee), see: air cargo security screening explained .
Missed cut-offs, screening delays, or no-space events can push freight to the next flight. That can trigger:
To reduce this risk, read: air cargo cut-off times and back-planning .
Use these buckets to compare quotes consistently:
| Cost item | Often included? | Often extra? |
|---|---|---|
| Air linehaul (chargeable weight) | Yes | No |
| Pickup and delivery | Sometimes | Often |
| Terminal handling | Sometimes | Often |
| Security screening | Rarely | Often |
| Fuel and peak surcharges | Rarely | Often |
| Oversize / non-stackable handling | Rarely | Often |
| Storage / waiting time / redelivery | No | Yes |
If a quote doesn’t state surcharge rules, you don’t have a quote. You have a placeholder.
Air freight cost is not one number. It’s a stack of linehaul, handling, surcharges, and exception fees. If you compare quotes using the same assumptions, control chargeable weight, plan around cut-offs, and avoid rework, you’ll prevent most “added later” charges and get predictable total cost.
Our mission is to simplify Australian freight and customs with practical guides and checklists that reduce delays, paperwork errors, and unexpected costs.
