Air freight quotes can vary by 30–40% between carriers for the same shipment, making rate comparison essential before you book. A few hours spent analyzing quotes upfront can save thousands on your next international shipment. Here's how to evaluate air cargo pricing like a professional buyer.
Understand the Quote Basics
Air freight pricing starts with two components: the base rate per kilogram and applicable surcharges. The per-kg rate fluctuates weekly based on fuel costs, demand, and seasonal peaks (typically September–November for holiday inventory). Surcharges—fuel, security, handling, destination—often add 25–35% to the base rate, so never ignore the line items.
Request quotes in writing, not over the phone. A written quote locks rates temporarily (usually 24–48 hours) and gives you a paper trail for comparison. Always specify your exact shipment weight, dimensions, origin airport, destination airport, and required delivery date.
Calculate Real Cost Per Kilogram
Don't just compare headline rates. Break down the total cost, then divide by the actual weight your shipment will be charged at. Carriers use chargeable weight, the greater of actual weight or volumetric weight (length × width × height ÷ 6,000 for standard volumetric calculation).
For example: a 50 kg box measuring 2m × 1m × 1m has volumetric weight of 333 kg (2,000 × 1,000 × 1,000 ÷ 6,000). You'll pay for 333 kg, not 50 kg. Once you know your real chargeable weight, calculate cost-per-kg for each quote—this reveals which carrier offers genuine value.
Compare Across Your Timeline
Faster service costs more; slower service costs less. Before comparing rates, lock in your required delivery window. Standard options typically break down like this:
- Next-day service (express): $4–8 per kg depending on route and distance
- 2–3 day service (priority): $2.50–5 per kg
- 4–7 day service (economy): $1.50–3.50 per kg
Requesting a quote for next-day delivery to rural Australia will naturally be pricier than 5-day delivery to London. Match your timeline to business need first, then compare carriers within that same service level.
Request a Breakdown of All Charges
The best quote format separates each cost clearly. Look for:
- Base rate (per kg)
- Fuel surcharge (typically 10–20% of base rate)
- Security surcharge (airport and TSA fees)
- Handling charges (terminal, documentation)
- Destination charges (local airport fees, customs clearance support)
- Taxes (GST, VAT, or import duties where applicable)
If a quote lumps everything into one figure, ask for a detailed breakdown. Opaque pricing hides cost creep and makes it impossible to spot overcharges.
Evaluate Carrier Reliability and Capacity
The cheapest quote means nothing if the carrier cancels your shipment or misses a deadline. Cross-reference each quote with:
- On-time performance metrics (ask directly; reputable carriers track this)
- Frequency of flights on your route (daily, 3x weekly, weekly)
- Capacity guarantees (some carriers offer space-only rates, others offer flexible rebooking)
- Track record with your industry (food, pharma, electronics, and fragile goods have specific requirements)
A carrier 5% more expensive but operating daily to your destination is worth the premium over a competitor flying twice weekly.
Factor in Hidden Terms
Read the fine print on every quote. Watch for:
- Minimum charge per shipment (often $150–400 for LCL—less than containerload)
- Capacity reservation fees (some carriers charge upfront to hold space)
- Rounding rules (whether they round to nearest 0.5 kg or full kg)
- Cancellation penalties (often 50% of total cost within 48 hours)
- Liability limits (standard is roughly $20 per kg unless you buy extra insurance)

Frequently Asked Questions
Q: What's the difference between CIF and FOB pricing for air freight? FOB means you pay freight costs and arrange insurance; CIF means the carrier includes insurance. Always confirm which applies, as it affects your total landed cost.
Q: How often do air freight rates change? Weekly or bi-weekly, depending on fuel prices and demand. Lock in rates in writing before you commit, and expect rates to shift 5–15% month-to-month.
Q: Can I negotiate air freight rates? Yes, especially for regular shipments or volumes above 500 kg. Carriers often offer volume discounts; always ask what rates apply if you commit to monthly shipments.
