The mini peak season for air freight that started in early March -- and then built momentum -- is expected to continue through the end of April. To date, all regions of Asia and the Indian Subcontinent have experienced strong demand for airlift, rate pressure from carriers and longer transit times, according to Hong Kong-based Trans Global Logistics (www.tglogistics.net).

Many origin gateways that had adequate space to meet demand have had to contend with cargo backlogs at transit hubs. The greatest rate pressure has been felt in Hong Kong, Shanghai and Taiwan.

The market has also seen a flurry of Fuel Surcharge (FSC) increases.   

According to the company, the rapid growth of the electronics industry in Southern China is a driving force behind the increase in direct flights from China to the U.S. and Europe.

The overall Asia air freight market is expected to cool down toward the end of April as rates ease and transit times return to normal.
