Multiple examples for me. Cathay about 5 years ago weighed my bag. Didn't care it was over weight, just made me carry my ski boots on cause they said the overall weigh was dangerous in overhead locker. Promptly put my boots back into said bag on the bridge! In December - Singapore Airlines weighed our carry on - at check in. Insisted i re distribute my weight. And escorted us to Oversize too - checky bugger! Both examples are stupid! If total weight is under the weight limit it shouldn't matter! Essentially the same weight ended up on the plane! We flew a bunch of times around Europe, one plane insisted that our bags wouldn't fit in over head - refused to weigh just took them off us. Another flight - they were checking the second bag fit in the cage thingy. Kevin and I were waved through - both our bags bigger than most that were checked. However we only had the one bag. I gave up carrying my boots in the carry on though. I think i will get the bag mentioned above @DidSurfNowSki YK loves his - and so i think will I!. However can't fit much else in them besides, boots, helmet, gloves and maybe a book or a ipad/tablet. Maybe a Surface Pro at a pinch. Surfstich have them - https://www.surfstitch.com/product/dakine-boot-pack-50l-boot-bag-black STM have it too - in a more colour version... http://stmonline.com.au/dakine-boot-pack-50l-nevada but cheaper!!
