What COVID Taught Air Freight — and Why the Lessons Are Being Relearned

There is a version of history where the logistics industry came out of the COVID-19 pandemic structurally better prepared for the next shock. Airlines had been forced to fly cargo-only missions on passenger aircraft. Freighter capacity had been expanded globally. Cold-chain infrastructure had been stress-tested against the largest vaccine distribution exercise in history.

The Iran conflict of 2026 is testing whether any of that learning stuck.

The 2020 paradox

When the pandemic struck in March 2020, air cargo faced a paradox: demand for urgent freight surged precisely as belly-hold capacity on passenger aircraft collapsed by more than 95%. Pharmaceutical companies trying to move clinical trial materials, automotive suppliers trying to keep just-in-time production lines running, and tech manufacturers sourcing components from Asia all ran into the same wall simultaneously: no space, no schedule, no certainty.

The industry's response was improvised and expensive. Air Canada became the first passenger airline to strip seats specifically to meet the surge in cargo demand. DB Schenker removed seats from three Icelandair 767s for regular Asia-Europe-US shipments. Virgin Atlantic flew dedicated cargo missions for the UK Department of Health between London and Shanghai. Rates on key lanes doubled and tripled within weeks.

What the research said

Academic research into how logistics service providers managed the COVID disruption identified five key resilience pillars: creating alternative revenue streams, enhancing transport flexibility, enforcing digitalisation, optimising logistics infrastructure, and managing personnel capacity. The common thread was flexibility — the ability to substitute, reroute, and adapt in real time when a planned route fails.

The on-board courier model demonstrated this flexibility precisely because it is, by nature, route-agnostic. A courier can board whatever flight is available — switching airlines, hubs, and connections in real time. When belly-hold capacity on a specific airline disappears, the courier boards a different aircraft. This adaptability, which seems like a premium when freight networks are working normally, became the only reliable option when they were not.

The 2026 retest

The Iran conflict is delivering a near-identical disruption pattern. Middle Eastern hub closures have effectively removed a critical node from the Asia-Europe freight network, pushing capacity down and rates up on the same corridors that COVID disrupted in 2020. The companies responding most effectively are, again, those with pre-established flexible capacity options — not those scrambling to find them mid-crisis.

The supply chain industry has a persistent habit of identifying the right lessons from each disruption and then underinvesting in applying them until the next disruption arrives. The question for logistics managers today is not whether the next shock will come. It is whether critical supply chains are designed with enough routing redundancy to absorb it when it does.
