Add one or more new Additional Card Members to your account through this page and you can earn 10,000 bonus miles after each Additional Card Member spends $500 or more in eligible purchases on their Card within their first 6 months of Card Membership starting from the date on which the Additional Card Member is added. The maximum you can earn as part of this offer is 40,000 bonus miles. Purchases made by other Additional Card Members on your Account will not count toward the $500 purchase requirement. Purchases made by eligible Additional Card Members will not be combined to satisfy the $500 purchase requirement. Your purchases as the Basic Card Member will not count toward the $500 purchase requirement. In rare instances, the Additional Card Member’s period to spend $500 may be shorter than 6 months if there is a delay in receiving their Card. Also, purchases may fall outside of the 6 month period in some cases, such as a delay in merchants submitting transactions to us or if the purchase date differs from the date they made the transaction. (For example, if they buy goods online, the purchase date may be the date the goods are shipped).
