In 20 years only ever heard port/starboard from students who had boats. Pretty pointless in aircraft where the control seats only face forward. (At least, for the flying part of things. I have had FA's multiple times say left and right backward, since they spend most of their time facing that way! So an absolute airframe-based direction system is not a bad idea for them. But we have CA side and FO side for that, instead of nautical terms.)
