Mileage accounts are always individual and therefore you cannot transfer your miles to another member’s mileage account. However, you do have the option of redeeming awards for friends or acquaintances from your personal credit.
If you wish to earn miles jointly as a family or with friends, you have the option of creating a mileage pool consisting of up to 2 adults (aged 18 or older) and up to 5 children (aged between 2 and 17 years). The award miles of all pool members are combined in a virtual mileage account and all adults are entitled equally to use the mileage credit, manage the mileage pool and invite members. Children do not have access to the total of the pool miles; they can only access the miles they have earned independently themselves.
