the pressure inside aeroplane is 11 to 12 psi and atmospheric pressure is 14 psi .
the tendency of fluids is flow from high potential to low potential, if you carry the pen inside and aeroplane with ink inside ink will star flowing out or start leaking because inside pen it is having higher pressure than aeroplane atmosphere..
