Share 'Looking for passenger on board JU 7149 in 1971'

Hi, This is my first time on this site so not sure how this works but I am looking for my biological mother who was on board JU 7149 MI travelling from Belgrade, Serbia to Canberra, Australia on the 10 October 1971. Her name was Aleksandra Ristevska born February 7, 1953. I'd like to know who she travelled with or any other information pertaining to her . Anything !!! Thank you
