I'd do a couple of mileage runs and aim for Gold, or else you may ask for a slight 'extension' so that you can up your status to Gold.

The biggest advantage to CX Gold is the guaranteed seat feature.

CX guarantees an economy class seat in a mileage earning class as long as you book it within 72 hours. Would SQ do that for you? Hahahaha!

Great when you want to book a V class mileage earning fare around Christmas and New Year... and when CX tells you that the waiting list is closed, just say you're a Gold member and the seat is miraculously confirmed for you?

CX elite members are also allowed to hold premium economy class seats ie emergency exit row without charge.

The biggest plus would be that you'd be op up'd occasionally whereas on SQ, it will be very very rare.
