After mentioning yesterday how Hawaiian Airlines allows credit card members to transfer miles between accounts for free, I thought it would be helpful to point out which loyalty programs allow households to share miles between family members:
British Airways: Up to 7 members in a household can pool miles, which was useful for those who took advantage of the 100k credit card bonus earlier this year. The current signup bonus is 50,000 points, which isn’t too shabby either (funny how spoiled we got with that 100k deal), and would allow you and a spouse to quickly get 100,000 Avios points (if you have kids over the age of 18 at home, they, too, can get the credit card and pool the miles with you).
Starwood: SPG allows you to transfer miles between accounts as long as the accounts share the same address. Again, this is useful for the SPG personal Amex card (info here) and SPG business Amex card (info here) since you can pool those bonuses (now 25k miles after $5k in spend).
Delta (sort of): If you have a mailing address in Asia, Delta will allow you to create a shared account, where you can transfer miles between up to 4 accounts. The initial fee is $200, which includes one transfer partner, and an additional $100 for every additional account you add.
Qantas: Qantas will allow you to transfer miles between family members 1 time per 12 months, for up to 100,000 miles (with a 5,000 mile minimum).
Japan Airlines: JAL allows family members to pool their points through their Family Club program. Family members earn miles on their own, but those miles can be pooled. Members must be in North, Central or South America, and a $30 annual fee is required.
Korean Air: Korean Air allows families to transfer miles between accounts. Family members must be registered to a given account in advance of transferring miles.
Etihad: Etihad Guest will allow you to create a Family Membership where up to 8 family members can pool their miles together into one account.
Any others I’ve forgotten?
