The number of guests you can bring into a Priority Pass lounge is primarily determined by the specific "membership plan" you hold, rather than a universal Priority Pass rule. If your membership comes through a premium credit card (like the Chase Sapphire Reserve or Amex Platinum), you are typically allowed to bring two guests for free per visit. Any additional guests beyond that limit will be charged a "guest fee," which is usually around $35 per person, billed directly to your credit card. However, if you have a "Standard" or "Standard Plus" membership purchased directly from Priority Pass, you may have to pay for every guest, including the first one. It is also important to note that individual lounges have their own "House Rules" and can restrict the number of guests regardless of your membership type if the lounge is near its maximum capacity. Some lounges also have age-based policies where children under a certain age (often 2 or 12) are admitted for free and do not count toward your guest quota. Always check the specific lounge details in the Priority Pass app before arriving to see the guest policy and any potential "busy hour" restrictions that might affect your group.
