Best credit card for lounge access under ₹40,000 annual fee

On credit limit increase: most banks auto-review every 6 months. If you use 30-70% of the limit and pay in full, you'll get an automatic increase. Don't call and ask for it explicitly — banks take it as a sign of credit hunger and sometimes lower the limit instead.

The customer care experience matters more than people think. I've had two cards with similar rewards, and the one from the bank with better support saved me ₹18,000 when there was a merchant dispute. Don't underestimate this.

The 'minimum due' trap is real. Banks love it because they charge ~36-42% interest on the carried-forward amount. If you can't pay the full bill this month, pay at least 50% — anything below that and the interest eats the rewards of the next 6 months.
