回复给Ryan Lei。
另一个有趣的点,我的账单日是 8.15,而 annual hotel credit 里有写
> “Annually” means the year beginning with your account open date through the first statement date after your account open date anniversary, and the 12 monthly billing cycles after that each year.
我的 hotel credit 到 2022.8.15 可以解读为新 benefit 开始的时间加一年,也可以解读为自然定义(明年开户日之后的第一个账单日),具体对于新用户是如何定义的,还需要更多数据点。
