One note: We pack a large DSLR and Video systems in backpacks and till recently never had a problem. Last trip when checking in with Qantas they made us put the backpacks on the scale and of course they are double the weight allowed, had to repack everything. The agent said they are going to start weighing all carry-ons.
When I leave Manila for Honolulu via Hawaiian Airlines they weigh my carry-on every time. It's standard practice with them.
