There was a old post where the guy successfully got the ltf eterna cause of cibil hit,
The post title is something premier to eterna after 18 mails
I am waiting for The card to see if there is any change in the limit (premier is 50k) so once I get the card and see the limit and T&C then I can give update. The app still show premier so its gonna take a day or 2 to reflect the update and I can wait for few days
and similarly I will wait for HDFC infinia directly and Apple card in US.
