They definitely leak, and below is response from BIC!! Please warn business travelers!! Ink got all over my paperwork and the shirt I was wearing! BIC response is don't use them. Sharpies DO NOT Leak!!
Liquid ink pens may leak on an airplane due to the change of air pressure in the cabin. This increased pressure may force ink out of the pen and cause leakage.
