Pack it in the original box THEN cover it with some sort of non-discreet paper or put it into a slightly larger box. Apple's original boxes are designed to shop products worldwide, via air. In fact, most Apple products come from Shanghai. My MBP flew PVG-ANC-MEM-YYZ on FedEx just fine! If you don't have the original packing go to your local apple retailer and ask if they have any.
