At the beginning of every year we're giving eligible Diamond members the chance to extend their status for one-year, one-time, for any reason.
注意：
1．您需要满足以下条件才能获得延期资格：
- 现在是钻石卡会员，而且有效期在 2023 年 3 月 31 日之前过期。
- 拥有总时长 3 年以上的钻石卡会籍历史记录（无需连续 3 年）。
- 至少入住过 250 晚以上（含积分入住），或者赚取过 500,000 以上基础积分（不含奖励积分）。
2．您必须通过前面的活动网址提交申请，通过审核后才能获得延期。
3．500,000 基础积分是指通过住宿获得的积分去除奖励的部分，也就是每消费 1 美元获得的 10 分，包含在升级钻卡之前获得的基础积分。
4．申请通过之后，您的钻石卡有效期将自动延期一年。
5．每名钻石卡会员终身只能获得一次免费延期机会，建议满足条件的希尔顿钻卡会员在有迫切需要时才提出申请。
活动条款：
A Diamond Status Extension will be awarded to select Hilton Honors members, who are current Diamond members and have earned Diamond Status for at least 3 years (consecutive or non-consecutive) and who have completed stays totaling at least 250 paid and reward nights OR who are current Diamond members and have earned Diamond Status for at least 3 years (consecutive or non-consecutive) and who have earned at least 500,000 Base Points over life of membership, pursuant to the standard Hilton Honors Terms & Conditions.
To be eligible, a Hilton Honors member must meet the stated criteria and currently be a Diamond Member. Points earned via bonuses, promotions and/or co-branded credit cards do not count towards meeting the Diamond Status Extension criteria. Qualifying Hilton Honors Members may enact this benefit once throughout the lifetime of their membership. The year during which a Hilton Honors member used a status match to achieve Diamond Status will not count as one of the three years of Diamond status required to meet the criteria. If a Member elects to use this offer, their Diamond status will extend for an additional year beyond when it would have otherwise expired. Once a Member elects to use this one-time offer and the extension is applied to their account, this action is considered final and is not reversible. At the end of the extension time period, Hilton Honors members will need to complete the requirements to maintain Diamond status pursuant to the standard Hilton Honors Terms & Conditions. If Diamond requirements are not met, Hilton Honors members will be placed in the appropriate tier pursuant to the standard Hilton Honors Terms & Conditions. Once earned, standard Hilton Honors Terms & Conditions apply.
A Diamond Status Extension is granted at the discretion of Hilton Honors Worldwide, LLC and may be ended, or amended with or without notice or compensation, at Hilton Honors' sole discretion.
