If you ever go to New Zealand, just be prepared to be weight. My SO got asked to weigh the carry-on. And oops the bag itself it's already 3.5 kgs. And how heavy is the G4 17 inches? And the magazines or books to read?
I think I am learning my lesson being in New Zealand early this year. Yes, I have to have a different approach when I am there. Certainly Tumi rollerbag is not an acceptable one.
