A 560lb Atlas Stone does not fit into the carryon sizing bin. Based on an eyeball estimate, I believe that the best you could get into the cabin would be 200lbs. It looks like Atlas Stones are generally mold-poured concrete, so you'd have to pour concrete into a rectangular shape. What is the maximum mass (in pounds) of concrete that can be poured into a carryon luggage rectangle compliant with BA policy? EDIT: 51 pounds, because that's the BA published limit on carryons. So, 16"x12"x3.451" using 133 lbs/ft^2 pre-mixed concrete, best case scenario. Make sure to take the handle's weight into account. https://www.britishairways.com/en-us/information/baggage-essentials/hand-baggage-allowances https://www.britishairways.com/en-us/information/baggage-ess... https://www.calculator.net/concrete-calculator.html?slablength=16&slablengthunit=inch&slabwidth=12&slabwidthunit=inch&slabthick=3.451&slabthickunit=inch&slabquantity=1&slabcal=Calculate https://www.calculator.net/concrete-calculator.html?slableng...
