In 2026, Singapore Airlines allows a limited form of mileage sharing through its KrisFlyer for Families program. Specifically, parents or guardians can link their accounts to those of up to five children (minors under 16). This allows the parent to transfer up to 50,000 KrisFlyer miles from the child's account to their own per calendar year for a small fee. However, standard KrisFlyer rules still prohibit the direct transfer of miles between two adult accounts (e.g., husband to wife or friend to friend). To bypass this, members are encouraged to add family members as Redemption Nominees. This allows you to use your own miles to book flights or upgrades directly for them without needing to move the miles between accounts. This system remains a staple for 2026 travelers looking to pool "household" rewards for major international trips.
