航空货运在低迷的状态下挣扎。虽然货运量下降使一些客改货生产线难以维持,但货机的维修和改装业务仍在继续。长期的市场预测依然是向好的,但可能与过去几十年的发展不一样。有一点可以确定的是,传统的货运需求增长与GDP的关系看似在减弱。 Air cargo struggled in a downturn. Although the decline in freight volume makes it difficult to maintain some of the passenger change production lines, the cargo maintenance and modification business is still continuing. Long-term market forecasts are still good, but may not be the same as in the past decades. What is certain is that the relationship between the growth of traditional freight demand and GDP seems to be weakening.
