The U.S. airfreight market generated revenues of $28bn in 2011, a 7.4 percent, year-over-year, increase. Although a seemingly positive development, this figure is on par with the revenues the industry recorded in the 2000-2001 financial year. Such statistics show that the U.S. - despite the domination of integrators FedEx and UPS - isn't immune to the sluggishness affecting the global airfreight market, a new study conducted by Air Cargo Management Group asserted.
