Recently back from a trip from UK to North Sulawesi via Hong Kong and Bali. The ONLY flights where my carry on was NOT weighed were the internal Indonesian flights - the international legs were particularly diligent, weighed and tagged everything. It's a problem but I'm resigned to having to put some camera gear through the checked in baggage and pay the excess where necessary, writing it off as the price of enjoying my hobby. The thing I fear most is not being allowed to take my carry on bag into the cabin and being obliged to put it in the hold, unprotected for that type of journey. With a strictly enforced 7 or 10Kg limit , there isn't much I can take into the cabin, SLR camera, maybe a lens, housing an a port. All else will have to make its way through the checked route. It IS well insured but especially on the outward leg, that really isn't the issue! Not an encouraging view I'm afraid but it reflects my most recent experience.
