OP, I concur with sal77's explanation. I’ve done this several time in the past for my wife who was booked on a separate ticket. However, I’m not sure if it will still work with all the recent ‘enhancements’ that EK have made to their system.
I'm sure your aware that your father’s ticket now needs to be a flex or flex plus ticket in order to be able to upgrade him before online check in opens and of course you will only be able to upgrade him if there is availability.
Good luck - hope it works for you both.
