Something that I believe is unique to the Philippine culture is the Balikbayan Box.
Balik means returning, Bayan means home. For the most part they are universal in size 24 x 24 x 24. They are filled with precious goodies from the US to bring back home to friends and family. Courier services will deliver Balikbayan Boxes door to door for about $65.00 with no weight limitations. Although it could take 30 days for the box to arrive.
Whenever sending a relative off from SFO, I would always look up at the monitor to locate the Philippine Airlines counter. Now I just look for the rows with Balikbayan Boxes.
