I traveled out of the Dipolog airport. I had two carry-ons that were both obviously over 7kg. PAL staff just waved me (the Kano) along while continuing to bust the chops of the Filipinos whose carry-ons were 1kg over. My wife just looked at me and said "Not fair." I told her it was because I am so gwapo.
Seriously, I would follow Adventine's advice upthread.
I am a little bit of a computer nerd. When we move to the Philippines I intend to break down two computers and send the parts in separate BB boxes.
