Is it possible to get LTF credit card without account relation possible for Standard chartered and Yes bank?
On CIBIL or C2C basis?
Yes Bank was offering LTF cards, but now they've stopped issuing but they may consider if you request them for LTF conversion. Though all the cards comes with their own FYF condition. It's wise to get the card then request as the charge will be levied only post 3 billing cycle if the FYF condition hasn't met.
For SCB, no they don't. But if you hold Ultimate card, they may consider cards like Smart / Digi Smart's LTF conversion, otherwise no. It's a hit or miss
