If you’ve been in the freight world for more than five minutes, you already know that air cargo price per kg isn’t a fixed number – it’s a moving target. One week a Shanghai → Chicago lane is at $3.50/kg, the next it’s pushing past $7. Add in fuel surcharges, security fees, and a sudden ecommerce boom, and you’ve got volatility that makes oil traders look calm.
The good news? With airlines representing more than 78% of global capacity now digitized on platforms like WebCargo, and with real-time indexes like the Freightos Air Index (FAX), you don’t have to guess anymore. You can quote, benchmark, and book based on live market conditions. As Zvi Schreiber, CEO of Freightos, put it recently:
Volatility isn’t going away. But with AI plus unique data, airlines and forwarders can turn it from risk into opportunity.
Let’s break down exactly what drives air cargo rates per kg in 2025, and how to get the most accurate air cargo quote online – in seconds, not days.
The Real Drivers of Air Cargo Price per KG
Forget vague averages – here’s what actually pushes air cargo rates up or down in 2025.
Route Density and Competition: Where You Fly Matters
High-frequency routes with lots of carrier competition – think Shanghai ↔ Los Angeles or Hong Kong ↔ Frankfurt – can be 20–30% cheaper per kg compared to thin routes with limited lift. On secondary lanes (say, AMS → Central America), sudden demand spikes can drive premiums up 40–50% above dense-lane averages, according to FAX Pulse data.
Anton Barr, VP of Market Data at Freightos, explains:
When demand jumps by 51% in one week, as we saw recently on AMS to Central America, forwarders that react quickly can lock in rates before prices climb.
That’s the difference between holding a competitive edge and eating margin.
Cargo Characteristics: It’s Not Just About Weight
The cost of air freight isn’t only tied to kilos – it’s tied to what’s inside those kilos.
- Dangerous goods (DGR): Expect surcharges of 10–25% above base rates, depending on hazard class.
- Temperature-controlled cargo: Pharmaceuticals and perishables often carry a $0.50–$1.50/kg premium due to equipment and handling costs.
- Oversized freight: Charged by dimensional weight – a 40 x 40 x 40 cm box weighing 5 kg is billed as 10.67 kg.
No forwarder wants to explain to a customer why their “light” shipment costs double because of dimensions. That’s why digital quoting tools now auto-calculate chargeable weight in real time.
Market Dynamics: Fuel, Seasons, and Black Swans
Rates move with the market, and forwarders who aren’t watching indexes are flying blind.
- Fuel surcharges: Typically 15–30% of base rate; volatile jet fuel prices make this one to watch weekly.
- Peak season (Nov–Jan): Rates climb 30–50% above off-peak averages, especially on Transpacific lanes.
- Disruptions: From Red Sea diversions to U.S. tariff policy changes, sudden shocks can slash or spike capacity overnight.
Numbers alone won’t keep cargo moving. This is where human expertise has to meet digital intelligence. The forwarders who win are the ones translating market swings into customer strategy. As Megan Kelley, VP of Enterprise Applications at of Crane Worldwide Logistics put it:
We’re not just pulling numbers; we’re proactively guiding clients on routing options that save them money and improve efficiency.
Service Level Requirements: Speed Costs More
Need guaranteed uplift tomorrow? You’ll pay for it.
- Express/priority services: Add 20–40% premiums per kg.
- Deferred services: Lower rates, but slower – often better suited for general cargo.
Forwarders are increasingly using dynamic quoting to offer both options in one branded quote, letting shippers decide how much speed they’re willing to pay for.
How to Get an Accurate Air Cargo Quote Online
The days of waiting 91 hours for a spot quote (yes, that’s the average) are over. Here’s how to get an accurate quote fast.
What You’ll Need to Provide
To get a precise air cargo price per kg quote, platforms will ask for:
- Commodity description & HS codes (for compliance and customs)
- Weight & dimensions (actual vs. volumetric weight)
- Origin/destination (airport codes or even postal codes for door-to-door)
- Transit time requirements (standard vs. priority)
Miss one, and your quote is either wrong – or delayed.
Where to Get Quotes: Digital Options
You’ve got three main digital routes to an air cargo quote online:
- Airline direct booking
- Best for very high-volume shippers
- Lowest base rates, but limited flexibility and value-added services
- Freight forwarder platforms
- Bundle services like customs clearance and insurance
- Typically carry a 15–25% markup on raw airline rates
- Digital marketplaces (like Freightos.com)
- Transparent comparison of multiple carriers and forwarders
- Ideal for SMB shippers who want instant options side-by-side
WebCargo: Where Data Meets Action

Or, as Sergio Escobar, Director of Operations & Technology at AIRMAX Cargo, put it:
We get a big advantage in quoting generation, business intelligence, rate management, and tracking the status of quotes.
We’re not just sending a quote in a PDF, we’re offering a customer an experience – with options.
That’s the difference between a transactional quote and a digital sales strategy.
The Bottom Line
Air cargo rates per kg will always be volatile. But with digitization, forwarders and shippers can finally move from guessing to knowing.
- Route density and competition can swing rates 30–50%.
- Cargo type, fuel surcharges, and service levels add layers of complexity.
- Digital quoting platforms cut average response times from days to seconds.
- And with tools like WebCargo, you can benchmark against real transactions, not stale spreadsheets.
In 2025, success in air freight isn’t about chasing the lowest air cargo price. It’s about mastering visibility, agility, and speed to quote and book smarter.
And that starts with knowing your price per kilo – live, accurate, and bookable.
