You cannot technically "add" a permanent second name to a single Priority Pass membership card; the membership is strictly non-transferable and must match the name on the boarding pass of the person presenting it. However, in 2026, you can easily bring guests with you. If your membership is through a premium credit card (like the Chase Sapphire Reserve or Amex Platinum), you typically get two complimentary guests per visit. Any guests beyond that, or guests on a "Standard" paid membership, are charged a fee—usually around $35 per person in 2026—which is automatically billed to the card on file. If you want a family member to have their own independent access without you being present, the best 2026 strategy is to add them as an "Authorized User" to your credit card account. This usually triggers a separate, secondary Priority Pass membership in their own name, allowing them to enter lounges whenever they travel alone.
