Had got a call on behalf of Yes Bank for an LTF Prosperity Rewards card. Told them I am not interested in anything other than Yes FP LTF. Was told one could apply for Yes FP LTF on Card-to-card basis if you have a card with 500000 limit or a net salary of 200000 per month. Though I was meeting the former on my ICICI Amazon-Pay card by then and have added more cards in the range afterwards, and was close to the latter as well, since Yes Cards have really lost it, I haven't been tempted enough to try it yet. Can give it a go, apply for the card online, and when the executive contacts, tell them you'd want it LTF....
