Hilton Honors made a one-time Diamond status extension part of the program in 2018 and has started to take requests for 2020.
Members that already know that they won’t requalify for Diamond status in 2019 can fill in their information, and Hilton will then send the invitation when the program is active for 2020.
You can access Hilton’s page for Diamond Extensions here.
Here are the requirements for requesting the one-time extension:
Minimum three years of Diamond status (don’t need to be consecutive)
250 nights (both paid and awards qualify) or 500,000 base points since joining Hilton Honors
This is an excellent program for those that may not be eligible for the status in one year due to lowered travel needs, and Hilton doesn’t care about the reason. You should only use it when you need it, though.
Here are the terms and conditions of the Diamond extension program:
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.
