Whether an add-on card (also known as a supplementary or secondary card) receives complimentary airport lounge access depends entirely on the specific credit card's terms and conditions. In 2026, many premium and super-premium cards, such as the HDFC Regalia Gold or YES Bank Marquee, explicitly extend lounge benefits to add-on cardholders, often allowing them to enjoy the same number of visits as the primary user. However, mid-range or "entry-level" cards often restrict this luxury to the primary cardholder only. It is also important to note that some banks have begun tightening these benefits; for instance, certain RuPay and Mastercard World debit cards have phased out complimentary access as of early 2026. If your card does offer the benefit, the add-on user usually needs to present their physical card at the lounge or use a linked app like DreamFolks or Priority Pass. Always verify your specific "Schedule of Charges" or benefits guide, as a lack of explicit mention usually means the add-on card will be charged the standard walk-in fee.
