I am travelling on Ethiopian airlines from Toronto to ADD and then on to Windhoek (WDH). My initial Air Canada flight permits a 10 kg carry on but my connections onto Ethiopian is limited to 7kgs. Just wondering if anyone has experience whether the airline actually weighs the carry on luggage and how strictly do they enforce limits. Some airlines only give closer scrutiny to bags that look heavy (I have camera equipment in a small backpack so it looks very compact and can't afford to be forced to gate check my gear). Thanks,
