I guess it is my turn to play the lottery 😂 My parents and myself were flying SQ326 to FRA yesterday. I was booked in J on a separate PNR to my parents who were on a redemption ticket in PEY on the same flight. Upon check-in at T3 F class reception we were advised that both my parents had been upgraded to J due to PEY overbooking (my mom has my partner TPPS card and my dad is KFES). Very surprised and grateful parents in J on this longish SQ jaunt, on what amounts to a rare upgrade occurrence on SQ.
