Just read an email from SAA where they said carryon baggage was limited to one bag and could not exceed 17 lbs in economy (business was two items).
It further states, weight scales have been placed at security points to weigh hand luggage after check in. Of course they were doing this for "passenger comfort and safety".

Knowing my roll aboard bag weighs about 10-12 lbs empty, I see this as a real problem. I do remember on a multiple country trip, including Australia about 10 years ago the same restriction was enforced on leaving Australia. That was a hassle having to repack everything.

Is this a trend that is happening on foreign airlines?
Is it enforced?
Soon to come here?
