For Platinum Card Members who prefer a streamlined supplementary card, Companion Platinum Cards^® are an option with no added annual fee. Companion Card Members can get benefits like Global Entry or TSA PreCheck fee credits and access to The Hotel Collection. ⁸.

A Companion Platinum Card is a specific type of "Additional Card" (authorized user card) offered by American Express to holders of the The Platinum Card®. It is important to distinguish it from the "Additional Platinum Card." While an "Additional Platinum Card" usually carries a fee (e.g., $195 per year) and comes with its own lounge access and elite status perks, the Companion Platinum Card is typically free of charge. It allows the primary cardholder to give a family member or friend a card to make purchases, which helps the primary member earn Membership Rewards points more quickly. The "Companion" user does not receive their own Centurion Lounge access or Hilton/Marriott elite status, but they often do get their own Global Entry or TSA PreCheck credit. It is essentially a "lite" version of the Platinum card designed for shared spending without the high cost of a full secondary membership. This makes it an excellent choice for parents who want to give their college-aged children a card for emergencies while still benefiting from the primary account's rewards.
