Recent data indicates no significant evidence of front-loading in U.S. air cargo from China, despite expectations of tariffs and confusion over de minimis rules, leading to lower cargo volumes. However, tonnages from China and Hong Kong to the U.S. saw notable week-on-week rebounds of 40% and 27%, respectively, though they remain below January averages. Worldwide air cargo is slowly recovering from a less severe Lunar New Year dip than last year, while average spot rates from Asia Pacific have increased, although rates from China to the U.S. have continued to decline.
