While I appreciate that the idea of SQD going to the flyer themselves is sacrosanct, I often do wish that SQD earned by minor children flying with their parent could somehow help the parent’s SQD out… This is probably just because I book an annual $10,000 round trip flight for myself, my wife and my daughter that earns me roughly 3,500 SQD…
My wife doesn't care about SQD since I gifted her 50K. We booked a few trips this year, mine on cash, and hers on points using a PR. Maybe use a similar strategy?
