Volumes down 2%, yet air cargo spot rates keep climbing: this peak season, capacity tightens before prices do
The least intuitive signal of this peak season has arrived. According to WorldACD data for week 43 (19-25 October), global air cargo tonnage fell 2% week on week, yet spot rates rose another 5% in the same week to $3.80 per kilogram, 38% above a year earlier. Fewer goods, higher prices: this rally is not being pulled up by overheated demand. The constraint on capacity and loading plans got to shippers first.
The increase is structural, not uniform. Spot rates rose 4% in week 42 and another 5% in week 43, two consecutive weeks of gains. By region, Europe led with a 7% rise, followed by Asia Pacific at 6% and Central and South America at 5%. On the main eastbound corridors, Asia Pacific to the United States reached $7.43 per kilogram, up 41% year on year, while Asia Pacific to Europe stood at $5.10. Blending spot and contract business, the full-market average was $3.33 per kilogram, up 3% week on week and 31% year on year. Year-on-year increases above thirty percent across the board are not a normal peak-season amplitude.
Why are prices rising while volumes fall? Two reasons. First, a genuine capacity gap: WorldACD notes that capacity out of the Middle East and South Asia remains 13% below its level in late February, and Riyadh was nearly closed to international freighter flights during the week, with regional adjustments further squeezing available belly space. Second, a timing mismatch. E-commerce restocking this year runs in two waves: the first, tied to the 11 November sales and early Black Friday, is in its intensive shipping phase now, and a second wave of Christmas replenishment follows in late November. With the peak stretched out, booking lead times have shifted earlier overall, and the contest for space now starts well before the peak weeks themselves.
The most telling number is the spread between spot and forward pricing. Market quotes from South China show trunk-line spot rates to Western Europe around $5 per kilogram, while forward bookings for mid-November are already being quoted at $7.20 to $7.80, a premium of more than fifty percent. That contango says carriers are pricing for the seasonal peak, and it makes the cost gap between booking now and waiting until November concrete rather than rhetorical.
The US lane carries additional context. Industry statistics put September air freight exports from China to the US up roughly 17% year on year, concentrated in the traditional origin regions of North and South China; capacity on the US lane is typically fully booked before the next uplift window, leaving little room for last-minute top-ups. On the India side, congestion at Mumbai terminals and truck queues that once stretched to 72 hours have pushed some India-to-US shipments originally planned by sea into the air, absorbing more transpacific belly capacity.
For high-value shippers, five practical steps. One, book capacity before comparing prices: the real constraint in peak season is whether space exists, not a few cents on the rate. Complete bookings 7 to 10 days ahead of uplift for high-value e-commerce cargo, and secure firm freighter allocations for November and December on your main volumes rather than relying on verbal quotes. Two, split allocations roughly 60/40 between spot and forward: if late-November replenishment is already on the plan, lock part of the forward space now and turn the price spread into a hedge instead of betting everything on spot. Three, tier your channels by cargo value: move low-value general cargo to Europe via sea-air combinations or the China-Europe rail corridors to free up peak air freight space, and keep high-value, time-sensitive replenishments on the air lane. Four, re-check surcharges on every shipment: fuel and security surcharges move frequently in peak season, so confirm quote validity, trigger conditions and adjustment caps, and reconcile the all-in cost of trunk haulage, handling and last mile before committing. Five, plan around the airspace control window over South China from 16 to 20 November, when schedules and capacity on some flights will be affected: cargo falling in those days should either move the week before or accept a documented delay, not count on a same-day fix.
The second restocking wave lands in late November, which leaves high-value shippers a window of roughly two weeks. Every line of the rate sheet is making the same point: one day earlier on securing capacity means one less chance of being rolled or repriced at the peak.
