Global air freight demand rose 4.4% year on year in August, with average yields posting their first month-on-month increase since April, according to IATA cargo traffic data.

Capacity, measured in available cargo tonne-kilometres (ACTKs), came in virtually flat against August 2025. That supply discipline lifted load factors by two percentage points and gave carriers room to push pricing higher for the first time in four months.

The combination of rising demand, recovering yields and tighter supply positions operators ahead of the traditional year-end peak shipping period, when air freight rates typically climb on holiday-season e-commerce and perishables flows.

"Yields rising for the first time in three months is an encouraging sign that cargo demand is holding firm," IATA said, attributing the August reading to stable capacity management and solid trade activity heading into the final quarter.

Which regions led the recovery?

North American carriers recorded the strongest regional growth at 6.6% year on year, followed by Latin American and Caribbean airlines at 5.1%. Asia-Pacific operators posted a 4.3% rise, while European airlines logged a 4.1% increase.

Middle Eastern carriers continued to struggle, with demand up just 1% as the Iran conflict weighs on regional operations. That demand growth trailed the 3.3% capacity expansion Middle Eastern operators added, pressuring regional load factors.

African airlines increased freight volumes 3.0% year on year, but that figure was dwarfed by a 14% jump in regional capacity, leaving operators there more exposed to yield erosion than their counterparts elsewhere.

What's driving the macro tailwind?

Global trade expanded 6% year on year in July, and the Global Manufacturing Output Purchasing Managers' Index rose in August, signalling sustained expansion in manufacturing activity. Those indicators typically feed air freight volumes with a one-to-two-month lag, which would keep demand indicators positive through at least October.

The picture is not uniformly positive. Jet fuel prices climbed 8.3% month-on-month in August, a cost headwind that carriers will need to recover through higher yields, fuel surcharges or both if the increase persists into the peak season. Belly-hold operators benefit from a structural hedge through passenger ticket revenue, but dedicated freighters face a more direct margin impact.

What should carriers watch through year-end?

The yield rebound is the signal to monitor. Three consecutive months of flat-to-falling yields had raised questions about whether the cargo supercycle that defined 2024 and early 2025 was running out of road.

A single August uptick is not a trend, but IATA's framing — demand holding firm while capacity stays disciplined — suggests operators believe they can defend pricing into the peak. Whether that defence holds will depend on how much belly-hold capacity returns as airlines add passenger flights for the winter schedule, and on whether freighter operators continue to retire older capacity at the pace seen earlier this year.

Regional pressure points also remain: Middle Eastern carriers need a resolution to the Iran conflict to lift utilisation on their hub-to-hub corridors, while African operators must fill the 14% capacity they have added or risk further yield compression in a region that already trades at a discount to global benchmarks.

IATA's next monthly data release will cover September and provide the first read on whether August's yield inflection carried into the peak quarter — a reading airlines, lessors and freighter conversion shops will all be watching closely.
