Air cargo enabled $157 billion in frontloaded trade in 2025, according to IATA — a figure that frames tariff-driven early shipping, not routine replenishment, as a defining feature of the year's air freight market.

The association's assessment positions the sector as the operational backbone of two distinct demand stories: shippers pulling orders forward ahead of trade measures, and the physical supply chain underpinning artificial intelligence infrastructure growth. Both pulled volume into belly holds and freighter decks at a time when ocean carriers were still digesting excess capacity.

The number itself deserves scrutiny. $157 billion represents the value of trade that moved earlier than normal purchasing patterns would suggest — not incremental trade created by air freight. Some of that cargo would have shipped anyway, by sea, later in the year. What frontloading changes is timing and mode, and both shifts carry rate consequences for shippers and forwarders.

Why did shippers frontload $157 billion of cargo?

Tariff deadlines did the work. When importers face a scheduled increase in duties, moving goods before the effective date locks in the lower rate, and air freight is the only mode that reliably compresses lead times from weeks to days for intercontinental lanes. In 2025, repeated rounds of trade measures — and the threat of more — kept that incentive live across transpacific and Asia–Europe corridors.

The commercial consequence cuts two ways:

• Shippers paid air freight premiums on cargo that would normally move by ocean, inflating landed costs on goods with thin margins.
• Carriers and forwarders captured yield on capacity that might otherwise have flown empty or at spot rates, particularly on lanes out of Asia.

The catch: frontloaded demand is borrowed demand. Cargo pulled into the first half of the year does not need to ship again in the second half, and IATA's own framing — "enabled" rather than "generated" — leaves open how much of that $157 billion was durable growth versus timing.

What does AI have to do with air cargo?

The second pillar of IATA's assessment is artificial intelligence. Building AI capacity requires physical goods: servers, high-value data-center equipment, semiconductors and associated hardware. These are classic air freight commodities — high value per kilogram, time-sensitive, and intolerant of ocean transit's volatility.

That demand profile matters because it is structural rather than cyclical. Tariff frontloading unwinds when trade policy stabilizes. Data-center buildouts continue for as long as capital expenditure plans hold, giving carriers a demand floor that spot-market consumer electronics never provided. IATA's decision to name AI growth as a support for the sector suggests it sees this as a multi-year demand driver, though the association has not quantified the tonnage or revenue share involved in its headline statement.

Who benefits, and who pays?

For carriers, the combination was favorable. Frontloading tightened available capacity on major trade lanes during the first half of 2025, supporting load factors and rates at levels weak ocean freight could not match. For forwarders, the same dynamics meant harder allocation negotiations and customers questioning why air premiums had risen.

For shippers, the arithmetic is straightforward: moving $157 billion of trade by air rather than sea means paying a multiple of ocean rates on those consignments. Whether that premium was recovered in avoided duties or preserved sales depends entirely on each shipper's tariff exposure — a detail the headline figure does not capture.

There is also a capacity question IATA's statement leaves unanswered. Freighters and belly capacity expanded only modestly through 2025 as passenger networks matured and freighter conversions continued. If frontloading recurs in 2026 — a realistic scenario given the trajectory of trade policy — the sector will meet it with little slack, and spot rates on exposed lanes will reflect that.

What happens when the frontloading stops?

The honest reading of IATA's figure is that part of 2025's air cargo strength is a one-time pull-forward. When tariff deadlines pass or stabilize, the volume that filled early-year capacity disappears from later months, and carriers will need AI-related demand, e-commerce and traditional cargo to fill the gap.

IATA's decision to publish the $157 billion figure signals confidence that the sector's role in global trade is growing in value terms, not just tonnage. Whether 2026 confirms that depends on two things the association cannot control: whether governments impose new trade measures that trigger another frontloading wave, and whether AI infrastructure spending maintains its current pace. Both point the same direction for now — toward continued pressure on air freight capacity and the rates that come with it.
