Booked versus flown

Ask a carrier how full a freighter is a week out and you'll get one number. Ask how full it actually flew and you'll get another — sometimes by double digits. Understanding that gap is a forecasting discipline, and right now it's worth real money.

The gap has names: no-shows, short-shipments, rolled bookings. A forwarder books space across three carriers for the same shipment and tenders to whichever looks best on the day. Nobody is doing anything wrong — that's how the market is structured. But the result is a booking file that overstates real demand by a margin that varies by lane, by season, by customer, and by how nervous the market feels that week.

Every one of those no-shows looks like a sales problem. Almost none of them are. They're an information problem: the booking file is not a demand signal, it's a demand signal plus an option-value signal, and the second one gets louder exactly when the first gets softer — because a nervous market books more widely.

It matters more right now than it has in years. IATA's June figures show demand up 8.5% year over year against capacity growth of just 4.4%, with the global load factor up 1.7 points to 46.9% and climbing. When space tightens like that, a no-show is no longer an empty position on a manifest. It's the shipment you turned away in order to hold the space — revenue you declined, in favour of revenue that didn't show up.

The carriers that manage this well do three things, none of them complicated and all of them rare in combination.

They track booked-to-flown as its own time series, by customer and by lane — not as an average across the network, where the signal drowns. A widening spread on a lane with flat bookings is a market telling you it's about to loosen, a week or two before the rate does.

They overbook against the pattern deliberately. Not recklessly — against measured materialization rates, the way passenger revenue management has done for decades. Cargo has been slower to adopt this discipline, partly because the data is messier and partly out of habit.

And they make the conversation with chronic no-show accounts about data rather than blame. A customer shown their own materialization rate, lane by lane, tends to either fix it or accept terms that price the option they've been holding for free.

Full planes aren't luck. They're the residue of knowing how much of what's booked will actually show up.
