Did you book through CX website or had to call the reservation centre to do it manually? They are great fares when the short haul is flown in J as I don't think the prices are noticeably different if they were bundled with Y class (i.e. the prices I am seeing on the website now). Also agree on your point about lounge access too although I am a bit puzzled why your dad got lounge access for all 4 legs...
