Just came from "W" Kuala Lumpur.
I used 1 SNA which was rejected 1 week prior to my check-in however i was upgraded to their marvellous suite upon check in which was a great surprise. Happy New year indeed!
If it was a 2019 SNA, you should get that back. Many have reported SNAs being denied just to get their Plat upgrade at check in. Different set of inventory, different set of rules, different set of people to deliver.
