Air cargo's peak season will develop unevenly across origin markets and commodity groups, according to Global Trade Magazine, a pattern that complicates capacity planning for carriers, forwarders, and shippers heading into the year's highest-demand window.

The core finding from the Global Trade analysis: peak season is no longer a single synchronized surge. Some origins and cargo segments will tighten into the busy period, while others will stay slack — a split that puts the burden of timing and routing decisions back on the shipper.

What does "uneven" mean for shippers?

The fractured pattern translates into capacity pockets rather than blanket tightness. Shippers moving time-sensitive cargo — pharmaceuticals, semiconductors, and e-commerce — will likely find space tighter and rates firmer than buyers moving slower-flowing traditional retail freight.

Where ocean schedules remain reliable, shippers keep boxes on vessels. Where ocean reliability has slipped, freight converts to air, lifting spot demand on the affected lanes. The result is a trade-lane mosaic: pressure on a few corridors, slack on others, all at the same time of year.

How are forwarders responding?

Forwarders are spreading bookings across carriers and origins rather than concentrating space on a single lane. That hedge mirrors the program-tonnage approach that took hold during the 2020–2022 disruption window, when shippers shifted exposure off the spot market and onto contracted capacity.

Carriers with large controlled freighter fleets — the integrated express operators chief among them — stand to capture more of the upside where demand concentrates, since their capacity does not depend on passenger belly-hold schedules.

How does capacity fit into the picture?

The global freighter fleet continues to expand, with additional units entering service over recent quarters and further deliveries scheduled. Belly capacity, by contrast, depends on passenger schedule recovery, which still varies market by market. That split inside the capacity stack is what allows integrators to price firmly even when overall tonnage is ample.

For shippers, the practical consequence: where belly space is thick, rates will stay disciplined; where belly space is thin, freighters set the level.

What should shippers watch next?

Origin-by-origin planning will beat a single playbook. Shippers with diversified country lists can shift tonnage between manufacturing regions as conditions change; those concentrated in one origin face a binary outcome on any given lane.

Global Trade Magazine expects peak demand to play out as overlapping mini-surges tied to specific origins and product flows, not a single synchronized event. That assessment will hold through the fourth quarter and into the early-year return-leg demand, when integrators typically tighten capacity and forwarders lock holiday and post-holiday program tonnage.

The forward-looking signal for shippers and forwarders: capacity on the lanes that matter is set to be tight; capacity on the lanes that don't, set to be loose — and the gap between the two will widen before it narrows.
