When I move up to a higher tier, how long do I keep the benefits for?
晋升至更高会员等级后，我能够保留优惠多长时间？
Regardless of how many Tier Miles you have earned or flights you have flown, your card validity and benefits are extended beyond the tier review date by an extra two months, even if you have not qualified to stay in your tier.
For example, if you achieve Silver membership on 17th June 2016, your tier review date will be at the end of June 2017, but you can still use your Silver card to enjoy extended benefits until the end of August 2017, even if you do not retain your tier.
Tier reviews always take place at the end of a month.

无论你赚取了多少定级里程或搭乘了多少次航班，即使你未能保留级别状态，你的会员卡有效期和相应优惠也会延长至级别评估期后两个月。
例如，你于2016年6月17日成为银卡会员，那么你的级别评估期将在2017年6月底，但你仍可使用银卡享受相应优惠至2017年8月底，即使你未能保留银卡会员级别。
级别评估通常在月底进行。
