A loophole I devised for beating the carry-on baggage size limit
Prepare a humanoid robot.Make it look exactly like you.Hollow out the inside,so it can hold your belongings.
Congratulations—you now have a human-shaped suitcase.
Put your things inside the robot.While you're at it,let it carry one more bag too.
The robot boards the plane.
Note:You are not permitted in the cabin.Please hide inside the suitcase instead,and check yourself in at the counter.
