Air cargo tonnages rebounded in week 38, IndexBox reports, as shippers moved freight ahead of the Chinese holiday period that traditionally shuts down manufacturing and export operations across the country.

The upturn marks a shift in momentum for a market that had seen tonnages soften in the preceding weeks. The pre-holiday push is a familiar seasonal pattern: ahead of the Golden Week celebrations, Chinese factories ramp up output and shippers accelerate shipments to avoid the capacity crunch and backlogs that build once plants close and airports thin out schedules.

For forwarders, the rebound signals tightening options. Carriers typically reduce freighter capacity out of China during the holiday window as demand from the manufacturing sector drops, and the combination of pre-holiday cargo surges with thinner belly capacity on passenger services tends to firm rates on outbound Chinese lanes. Shippers who wait until the last days before the holidays often face premium pricing and space constraints on services to Europe and North America.

The week 38 recovery also offers carriers a measure of relief. Higher tonnages ahead of the holidays support load factors and give operators room to hold — or push — rate levels before the seasonal dip that follows the celebrations, when export volumes typically fall until demand rebuilds toward the year-end peak season.

The bounce in tonnages suggests cargo owners have once again front-loaded shipments rather than risk holiday-period delays. That behavior cushions the immediate post-holiday slowdown but can amplify the depth of the dip once the rush subsides.

IndexBox's data will be watched closely in the coming weeks for signs of how sharply volumes fall once the holidays begin, and whether the subsequent rebound into the fourth quarter confirms the strength of peak-season demand. For now, the direction of travel is clear: tonnages are rising, capacity out of China is about to tighten, and shippers with flexible scheduling have likely already secured their space.
