Recently took a number of flights with the little one, which clocked up quite a few miles (all within last 12 months). However there is no FF account associated with the kid, (except being part of the redemption group). So as far as earning miles they have not been added. Whats your suggestion? Open a OW account with another airline or is there a way to add miles to my existing CX account? Would be a shame to waste them (around 30k on both QR and CX).

Do let me know your thoughts please.
