From the International Air Transport Association: Cargo Plummets 22.6% in December (hat tip Bob_in_MA)

In the month of December global international cargo traffic plummeted by 22.6% compared to December 2007. The same comparison for international passenger traffic showed a 4.6% drop. The international load factor stood at 73.8%. For the full-year 2008, international cargo traffic was down 4.0%, passenger traffic showed a modest increase of 1.6%, and the international load factor stood at 75.9%. “The 22.6% free fall in global cargo is unprecedented and shocking. There is no clearer description of the slowdown in world trade. Even in September 2001, when much of the global fleet was grounded, the decline was only 13.9%,” said Giovanni Bisignani, IATA’s Director General and CEO.” Air cargo carries 35% of the value of goods traded internationally. … “2009 is shaping up to be one of the toughest years ever for international aviation. The 22.6% drop in international cargo traffic in December puts us in un-charted territory and the bottom is nowhere in sight. Keep your seatbelts fastened and prepare for a bumpy ride and a hard landing,” said Bisignani.
