Depends from P2P
there are no cards given as LTF which have unlimited lounge access (until you have extremely high NRV with the bank).
Online rewards/cashback is subjective to your usage
if approx 75% of your usage is on amazon, then apay is for you (ltf)
for diverse payments, axis ace will give 2% (but not sure if this is given as ltf or not)
you need to do research by yourself..... people here can only suggest the best ones from the list...
