Price moves last

In air cargo, price is the last thing to move. IATA's August figures show how long the wait can be.

Demand was up 4.4% year over year. Capacity was trimmed by 0.1% worldwide, and by 2.5% in North America and 3.5% in Europe. The load factor rose two points to 46.0%. Jet fuel cost 79.2% more than it did a year earlier. Every input that should push a price up had been pushing for months. And yet August was the first month since April in which yields rose from the month before.

That lag is not an accident. It is how the business is built.

Most of the freight on a cargo aircraft moves under contracts and allotments agreed months earlier, at rates set for the year, with a fuel surcharge that catches up on a lag of its own. The spot market reprices weekly, but spot is only part of the aircraft. So when the market tightens, the price on most of the hold does not change. Only the last few pallets reprice, and only when someone is willing to say no to a booking at the old rate.

That is the part commercial teams find hardest. Saying no to volume feels like losing. A sales organisation measured on tonnage will fill the aircraft at the contract rate and count it as a good month, even when the load factor says the same freight would have flown a week later at a better one. Pricing sees the load factor. Sales sees the customer. The two rarely see each other's numbers at the same time, and the lag lives in that gap.

Costs, meanwhile, move at the speed of the oil market. For a few months the carrier absorbs the difference, and this summer the difference has been very large.

Shortening the lag is a discipline, not a formula. It means holding back a measured share of capacity from allotments on the lanes that are tightening, so that there is something left to reprice. It means giving sales the load factor by lane, by week, so that the no is a shared decision rather than a pricing veto. And it means reading a two-point gain in load factor for what it is: not a good month, but a signal that the price on the whole aircraft is out of date.

The market tightened in the early summer. The price caught up in August. The carriers that make money through the winter will be the ones that close that gap to weeks.

Fuel moves at the speed of the market. Price moves at the speed of the contract. Margin lives in the months between.
