Air Cargo News has published the latest instalment of its long-running Putzger Perspective column, with veteran air cargo journalist Ian Putzger turning his attention to what he calls aircraft production "speed bumps" — the manufacturing disruptions that continue to slow jet deliveries across the industry.

The column lands at a moment when air cargo capacity planning is acutely sensitive to delivery schedules. Production shortfalls at the major airframers feed directly into the freighter market in two ways:

• Fewer new widebody passenger aircraft, which means fewer candidate airframes feeding passenger-to-freighter (P2F) conversion programmes
• Slower freighter deliveries, including factory-built freighters, tightening capacity growth on lanes that depend on fleet expansion

What does the column cover?

Putzger, a regular contributor to Air Cargo News who has covered the air cargo beat for decades, uses the Perspective format to draw connections between manufacturing-floor problems and their downstream commercial consequences for airlines, freight forwarders and shippers.

The central premise of this instalment is that production-line disruptions — the "speed bumps" of the title — are not a temporary nuisance but a structural drag on how quickly operators can add capacity.

For freighter operators, that matters commercially. Conversion shops and integrators bid on feedstock availability years ahead. When new-build output stumbles, older aircraft stay in service longer, retirements slip, and the used-airframe market that supplies converters tightens.

For forwarders and shippers, the practical effect is felt in charter pricing and in the availability of main-deck capacity on trade lanes where bellyhold space alone cannot absorb seasonal peaks. Any delay in freighter deliveries pushes carriers toward extending leases on existing metal, which raises unit costs.

Why a column about factories matters to rates

Air cargo rates are, at bottom, a function of capacity against demand. The column's focus on the supply side of that equation — the production line rather than the runway — is a reminder that rate trajectories can be set years in advance, on factory floors in the US and Europe.

Readers of Waybill Wire who plan capacity on transpacific, transatlantic and intra-Asian lanes will recognise the pattern: whenever freighter induction slows, the marginal tonne gets more expensive to move, and integrator networks competing for the same lift pass those costs through.

The takeaway

Putzger's column does not suggest the production problems are insurmountable, but it frames them as persistent friction rather than a one-off — a reading with clear implications for anyone forecasting freighter capacity growth over the coming delivery cycles.

With the full analysis available at Air Cargo News, the direction of travel for capacity planners is clear: until airframers smooth out their speed bumps, main-deck capacity will stay tighter, and older freighters will fly longer than their operators originally planned.
