Global air cargo demand rose 4.4% year-on-year in August 2026, while capacity was essentially flat — down 0.1% — according to data released by the International Air Transport Association (IATA) on 30 September.

International operations drove the growth. Demand on international services, measured in cargo tonne-kilometers (CTK), increased 5.3% against August 2025. Available cargo tonne-kilometers (ACTK) on international operations edged up just 0.1%.

The gap between rising demand and static supply tightens the demand-capacity balance on key trade lanes, with implications for yields at a moment when fuel costs are climbing sharply.

What does the operating environment look like?

IATA highlighted four factors shaping the cargo market:

• Global trade grew 6.0% year-on-year in July, extending a run of 33 consecutive months of year-on-year expansion.
• Jet fuel prices rose 8.3% month-on-month in August and stood 79.2% higher than a year earlier.
• Manufacturing output PMI increased 0.3 points to 53.0 in August.
• New Export Orders Index rose 1.4 points to 51.4.

Both manufacturing indicators remained supportive of air cargo demand, IATA said. The PMI readings above 50 signal expansion in the industrial activity that generates freight volumes.

The fuel figure carries the clearest cost consequence. A 79.2% year-on-year increase in jet fuel prices compresses cargo margins even as load factors improve, and it strengthens the case for the higher yields that tight capacity typically supports.

Which trade lanes are growing — and which are not?

Performance diverged across major corridors in August. Asia–North America recorded the strongest growth. Within-Asia lanes followed, then Europe–North America and Europe–Asia.

Gulf-linked corridors were the outlier. IATA reported that lanes connected to the Gulf remained disrupted by the conflict in the Middle East, capping volumes on routes that normally serve as freight interchange points between Asia, Europe and Africa.

The pattern favors carriers with dense Asia–North America and intra-Asia networks, while operators reliant on Gulf hub flows continue to face route and capacity constraints.

What happens next?

With demand growth outpacing capacity and manufacturing indicators still in expansion territory, the fundamentals point to continued tightness in the air freight market — provided fuel prices and Middle East disruption do not erode the demand side of the equation.
