spg card 15 Elite Night Credit

개인 카드 여러장 있으셔도 15 밖에 못 받으시고 

비지니스 카드로 추가 15 입니다

아 그렇군요. 답변 감사합니다 그럼 한번에 15 들어오나요? 

매리엇 공홈이나 앱에서 계정 정보 한 번 확인해 보셨나요?

거기 보면 한 방에 이해될 거에요.

개인 비즈 각각 15박 맥스는 위에 이미 언급됐고,

구SPG 카드는 이미 오래 전에 매리엇 본보이 카드로 변경됐을 거에요.

Marriott Bonvoy Credit Card from Chase Elite Night Credits: Upon opening your Card Account, a maximum of 15 Elite Night credits will be credited to your Marriott Bonvoy® member account within 60 days. On or before March 1 of each calendar year, a maximum of 15 Elite Night Credits will be credited to your Marriott Bonvoy® Member Account operated by Marriott International, Inc., in accordance with Marriott Bonvoy terms and conditions. To be eligible to receive the 15 Elite Night Credits with this Card, you must be the primary Cardmember, your Card account must be open as of December 31 of the prior year, and you must have an active Marriott Bonvoy Member Account linked to your credit card account.
This benefit is not exclusive to credit cards offered by Chase. A maximum of 15 Elite Night Credits will be awarded through this benefit per Marriott Bonvoy Member Account even if the Member has more than one credit card linked to their Marriott Bonvoy Member Account, unless you have both a small business Marriott Bonvoy credit card account and a consumer Marriott Bonvoy credit card account; then you may receive a combined maximum of 30 Elite Night Credits (15 per credit card account). If your Marriott Bonvoy Member Accounts are merged, if both accounts have received 15 Elite Night Credits, only one 15 Elite Night Credit will remain. Separate promotional offers of Elite Night Credits will not count toward this per-Account maximum but may have their own limits; see promotional terms at time of offer. Chase is not responsible for offer fulfillment or the provision of or failure to provide the stated benefits and services.
