Domestic vs. International Airport Lounges
Airport lounges in India are segregated strictly past security hold areas. If you are flying on a domestic flight, you cannot access international lounges even if your credit card offers unlimited international passes. Domestic lounges are typically accessed by swiping your primary bank card directly at the lounge counter for a nominal verification hold (₹2 on Visa/Mastercard, ₹25 on RuPay).
