Since there a couple posts mentioning ANA CC.
If you have a ANA premium card (gold or higher), gain Platinum status on ANA, you are able to swap the card for a “Super flyers card” version of it which allows you retain Platinum status level benefits indefinitely (and family members) as long as you keep the card. No need to jump through hoops every year. The status applies for other star alliance members as well if you fly those.
