Hilton announced following policy to Greater China members by Chris Nassetta:
1, If a member did not re-qualify for his/her elite membership in 2019, his/her current elite membership will be extended to 31st March 2021.
2, If a member qualified for elite membership (Gold/Diamond) in 2019, his/her elite membership will be extended to 31st March 2022.
I would expect Hilton to extend such hospitality to all members.
