“Actually, in air cargo the challenge is always belly space versus freighter capacity,” says Harvard Logistics Professor Issa Baluch. “That is the age-old question. But both seem to work in cycles.”
“Belly space becomes precious when business in air cargo takes off, and in the end, full bellies help to promote freighter build up. We need both freighters and belly lift. There is simply no conflict. In fact, both generally complement each other,” he said.
“I need to stress ‘precious’ because bellies just naturally ought to cost a little more than regular freighter service,” Professor Issa declared.
