e-Cargonews Asia reports on a switch back from air freight to shipping. Key explanatory quote:
Imbriani pointed to a combination of factors that have made shipping lines a viable alternative to air freight. Sailing schedules have become more reliable, capacity is up, and the use of special equipment and containers, such as temperature and humidity control devices, have made it possible to move electronics in ocean containers, he said.
And of course, this will help too.
