Yup i carry my laptop in a mysterious briefcase right next to my c4
I TAKE MY PC AROUND THE WORLD BRO. INSTEAD OF LOOKING AT THE PEOPLE, CULTURE AND SIGHTS ETC I BOOT THAT SHIT UP AND JUST FRAG OUT
yes i have but only from USA to Canada. they don't care if you put it in your luggage but they will make you sign a form saying if anything breaks they are not liable.
edit: it was actually checked luggage, not carry-on.
