No. The only person who can access the lounge is the person named on the eligible Mastercard payment card. For security reasons, the lounge will verify the name of the cardholder against their boarding pass and their identification card / passport.

No, your wife generally cannot use your physical credit card to gain entry to an airport lounge if she is not the primary cardholder or an authorized user. Lounge access is a high-fidelity non-transferable benefit; agents at the reception desk will strictly compare the name on the credit card (or digital membership like Priority Pass) with the name on the boarding pass. If the names do not match, she will be denied entry. To solve this in 2026, the high-fidelity strategy is to add your wife as an Authorized User (Add-on Cardholder). Most premium cards like the Amex Platinum or Chase Sapphire Reserve allow this for an additional fee, and the authorized user receives their own high-fidelity card and lounge membership in their own name. Alternatively, if you are traveling together, you can usually bring her in as a high-fidelity "Guest," but if she is traveling alone, she must have a high-fidelity card in her own name to enjoy the benefits of the lounge's high-fidelity amenities.
