To determine if your debit card provides airport lounge access, the most direct method is to check your bank's mobile app or website under the "Rewards" or "Benefits" section. In 2026, many premium "Platinum," "Signature," or "Infinite" debit cards (especially from banks like HDFC, ICICI, or Chase) include complimentary visits to domestic and international lounges. You can also look for a Priority Pass or LoungeKey logo printed on the back of the card. Another reliable way is to download the "Mastercard Travel Pass" or "Visa Airport Companion" apps and enter your card details; these apps will instantly show your eligibility and the number of free visits remaining. Some banks also have "minimum spend" requirements in the previous quarter to unlock the benefit, so it is important to check the specific "Terms and Conditions." If you are at the airport, the lounge receptionist can swipe your card to verify its current status, but be aware that if the card is not eligible, you may be charged a "walk-in" fee ranging from $30 to $50.
