Early in 2026, air freight is sending mixed signals to shippers. On paper, global air freight volumes appear relatively soft, and capacity growth looks modest but stable. Yet in day-to-day operations, many supply chain teams are encountering tight booking windows, rolled shipments, and inconsistent service levels. This disconnect is leaving shippers frustrated and often unprepared as air freight volatility shows up in places they didn’t expect.
The reason is that air freight reliability is no longer dictated by headline demand alone. Instead, pressure is moving unevenly through interconnected cargo networks, driven by cargo mix, carrier behavior, and regional bottlenecks that rarely show up in high-level metrics.
Why Air Freight Feels Unpredictable Right Now
At the macro level, overall air freight capacity can appear sufficient. Aggregate indicators such as cargo tonne-kilometers (CTK) and capacity utilization suggest balance in many markets. But those averages conceal what shippers actually experience when booking space on specific lanes, days, or routings.
In reality, air freight challenges have become increasingly lane specific. Capacity that looks available globally may be inaccessible where it matters most, particularly on regional routes that feed long-haul services. Belly cargo represents more than 54% of total air cargo lift, according to IATA data from November 2025, up from a low of 25% during the pandemic. It remains constrained by delayed aircraft deliveries and limited fleet growth. As a result, even modest demand shifts can quickly trigger localized air cargo congestion.
The Limits of Headline Metrics
Global volume trends are useful for context, but they are blunt tools when it comes to planning. Averages hide congestion building at individual hubs and obscure reliability issues that emerge upstream or downstream of major trade lanes.
A trans-Pacific route may show adequate capacity overall, but if the feeder flights into key Asian transit hubs are full, that long-haul capacity becomes theoretical rather than bookable. This is where many shippers get caught off guard: planning based on high-level data while missing early signs of friction developing elsewhere in the network.
How Capacity Pressure Moves Through Air Cargo Networks
Air cargo does not move in isolated point-to-point lanes, but flows through a tightly linked network of regional flights, transit hubs, and long-haul services. When pressure builds in one part of that system, it rarely stays contained.
A clear example comes from recent developments in Asia. Strong U.S. demand for high-tech and AI-related exports from Southeast Asia has tightened intra-Asia capacity because much of that cargo is routed through regional hubs before moving long haul.
According to the Journal of Commerce, transit carriers are prioritizing first-leg capacity for long-haul shipments, which has intensified congestion at hubs such as Hong Kong, Taipei, Singapore, Incheon, and Narita. Even though overall volumes may not appear elevated, this upstream pressure limits flexibility and reliability across the network.
Cargo Mix Is Reshaping Availability
Another key driver of volatility is the changing composition of air cargo demand. Growth in high-value, time-sensitive shipments — including semiconductors, electronics, and cloud infrastructure components — is reshaping how capacity is allocated.
Priority cargo is booked earlier, protected more aggressively, and often displaces freight with flexible delivery windows. As this cargo mix shifts, cutoff times move earlier and last-minute availability shrinks, even in markets where demand growth appears modest. For shippers outside these priority categories, availability can disappear quickly without any obvious change in headline data.
Carrier Behavior Matters More Than Demand
Carrier strategy now plays a larger role in shaping shipper experience than raw demand alone. Airlines continue to manage capacity carefully through aircraft allocation, yield optimization, and scheduling adjustments. “Available capacity” does not always translate into bookable space at predictable rates.
