Pelican 1450 makes a great Mavic Pro travel case
I made this layout by myself! The Pelican 1450 fits underneath the airline seats so it's perfect as a carry-on (so long as you don't mind having minimal feet space). My Mavic Pro was bought as a combo along with 2 extra batteries and a whole mess of other accessories so I wanted a complete easy-to-configure option for making sure this whole setup was protected. This seems to fit the bill nicely.
