To reach or keep Platinum status, you'll need to earn 14,000 status points or 60 status nights.
To reach or keep Diamond status, this can only be done by earning 26,000 status points.
As an ALL Accor+ Explorer member, you'll always have at least Gold status while your Explorer subscription is active, since Explorer members receive 30 status nights each year.
Keep in mind that your status is assessed, and your status nights and points reset at the end of each calendar year.
