Generally, you cannot use your wife’s debit or credit card for airport lounge access if she is not present with you. Most lounge programs, including Priority Pass and those offered by premium banks, have strict "Cardmember Presence" rules. The name on the physical or digital card must match the name on the boarding pass of the person entering the lounge. In 2026, lounge staff are increasingly vigilant about checking government-issued IDs alongside the lounge membership card to prevent "card sharing." If the card offers "guest access," you could enter for free only if your wife is there to "sponsor" you as her guest. If you want to use the benefits while traveling alone, the best solution is for your wife to add you as an Authorized User on her account (if the bank allows this for her specific card type). This would provide you with your own card in your own name, which would then be valid for lounge entry. Attempting to use a card with a different name can lead to an awkward rejection at the front desk and, in some cases, a report to the card issuer for a violation of the terms of service.
