Adding Authorized Users to Amex Platinum: Cost vs. Benefits

The American Express Platinum Card occupies a unique space in the premium credit card market. With its $895 annual fee and positioning as a “membership card” built around benefits rather than earning rates, the Amex Platinum appeals to frequent travelers willing to pay for convenience and access. One feature that can extend this appeal is the ability to add authorized users—a strategy that comes with its own cost-benefit math.

Right now, new cardmembers can earn up to 175,000 bonus points after spending $12,000 in the first six months of card membership, though offers vary by applicant. Once you’ve secured the card, you face a decision: should you add other people to your account as authorized users?

The straightforward answer depends on who you’re adding and how much they’ll use the card’s perks. Adding an authorized user to the Amex Platinum costs $195 per year—a meaningful additional investment on top of the card’s base annual fee. That price tag puts the decision squarely on a single question: will the benefits they unlock be worth at least $195 annually?

Lounge Access: The Primary Value Driver

The most tangible benefit available to Amex Platinum authorized users is access to premium airport lounges. Authorized users enjoy the same lounge privileges as the primary cardholder, including American Express Centurion Lounges, Priority Pass network lounges, Delta Sky Clubs (on same-day Delta flights, limited to 10 annual visits), and Plaza Premium locations.

How Guest Fees Create Opportunity Cost

Bringing guests into Centurion Lounges normally costs $50 per adult and $30 per child ages 2 to 17; children under 2 are free. If your authorized user visits a Centurion Lounge, they enter directly without needing a guest pass and incur no fee. The same applies to Delta Sky Clubs, where each guest visit costs $50 to accompany you.

American Express offers two paths to waive Centurion Lounge guest fees. The first requires charging $75,000 on your Platinum Card within a calendar year—a high bar for most travelers. The second path is simpler: add an authorized user. Your authorized user can enter Centurion Lounges and Delta Sky Clubs independently, requiring no guest passes and incurring no fees. If your authorized user visits lounges four times per year, the $195 annual fee effectively pays for itself through guest fee savings alone.

Priority Pass and Global Lounge Network Enrollment

Access to Priority Pass lounges works slightly differently than Centurion Lounges. Authorized users must call the number on the back of their Amex Platinum card to enroll in Priority Pass—they cannot enroll online. Once enrolled, they gain access to that global lounge network. The other lounge types in the American Express Global Lounge Collection (Centurion, Delta Sky Clubs, and Plaza Premium) require nothing more than presenting the authorized user’s Platinum Card at entry.

Who Benefits Most From Lounge Access

Families with frequent travelers stand to gain the most from lounge access benefits. A household where multiple members travel together can eliminate guest fees by converting guests into authorized users. Families with children over 12 can especially benefit, since children at least age 13 can be added as authorized users and enter lounges independently.

Global Entry and TSA PreCheck Credits

A second major benefit available to authorized users is the statement credit for trusted traveler programs. Each authorized user receives a $120 credit toward Global Entry or up to $85 toward TSA PreCheck application fees once every four years—the same frequency as the primary cardholder.

This benefit works broadly. The credit triggers on any qualifying charge, not just for the authorized user’s own membership. If an authorized user charges a Global Entry or TSA PreCheck application for a friend or family member, it still counts toward the annual credit. For a first-year authorized user who applies for Global Entry, the $120 credit covers most of the $195 annual fee immediately. Over a four-year cycle, each authorized user can unlock $120 to $85 twice per account term, creating substantial value for families with multiple travelers.

Hotel Elite Status Without Additional Spending

Authorized users on the Amex Platinum receive complimentary elite status with three major hotel programs: Marriott Bonvoy Gold Elite, Hilton Honors Gold Elite, and Leaders Club Sterling status from The Leading Hotels of the World. Both primary and authorized users can enroll for these statuses directly online.

The value of these statuses compounds if the authorized user travels to hotel properties within these chains. Bonvoy Gold and Hilton Gold typically provide room upgrades when available, bonus earning on stays, and additional on-property amenities like late checkout or dining credits.

Authorized users can also access two high-end hotel programs tied to the card: Fine Hotels + Resorts and The Hotel Collection. When booking through Fine Hotels + Resorts, stays earn 5 points per dollar spent, and cardmembers receive elite-style perks including room upgrades upon arrival, daily breakfast for two, guaranteed 4 p.m. late checkout, noon check-in when available, complimentary Wi-Fi, and a $100 experience credit per stay. The Hotel Collection requires a minimum two-night stay but offers similar prestige benefits to cardmembers who book directly through the program.

Car Rental and Ground Transportation Status

Authorized users receive complimentary elite status with three car rental programs: Hertz Gold Plus Rewards President’s Circle, Avis Preferred Plus, and National Emerald Club Executive status. All three can be enrolled through American Express’s website.

These memberships unlock benefits like shorter pickup and return times, guaranteed vehicle categories, and lounge access at certain rental locations—particularly valuable for business travel or rental scenarios where convenience and speed matter.

Account-Level Benefits: What’s Shared, What’s Not

The Amex Platinum offers several annual credits that work across the entire account. Purchases by any cardholder—whether primary or authorized user—trigger these credits, up to the annual cap. The Equinox statement credit provides up to $300 per calendar year toward fitness memberships. If the primary cardholder never uses Equinox, but an authorized user does, their charges still trigger this credit. This is practical for households where family members have different fitness preferences.

However, some benefits do not extend equally. The Uber Cash benefit provides $200 per calendar year to the primary cardholder only (split as $15 per month plus an additional $20 in December). Authorized users receive no separate Uber Cash allocation, and the benefit can be linked to only one Uber account per card.

Most importantly, there is only one welcome offer per account. Purchases by any authorized user count toward the primary cardholder’s spending requirement, but the account receives just one welcome bonus—not separate bonuses for each cardholder.

Building Credit History Through Authorized User Status

Adding an authorized user also opens the door to credit-building opportunities. American Express requires parents to trust authorized users with access to the card. Charges incurred by an authorized user remain the primary cardholder’s responsibility, and the card balance must be paid in full each month.

For younger family members, this can be a valuable credit-building tool. Children can be added as authorized users starting at age 13. American Express reports the positive payment history of all cardmembers to credit bureaus once they reach age 18, helping them establish a credit record early. This approach works best when the authorized user makes regular, modest charges on the account that the primary cardholder pays in full and on time.

Making the Financial Case

Deciding whether to add an authorized user requires honest assessment of how much value they’ll extract. A business traveler who visits airport lounges frequently, applies for Global Entry, stays at premium hotels, and rents cars regularly may generate $400 or more in annual value—making the $195 fee an obvious yes. The fee pays for itself quickly and provides ongoing savings.

A casual leisure traveler who rarely enters lounges, doesn’t need trusted traveler credentials, and books hotels independently may never approach $195 in benefits, making the expense hard to justify.

The Amex Platinum authorized user option works best for households where the additional cardholder travels meaningfully, uses premium lounge access regularly, or applies for trusted traveler status. When those conditions align, the $195 annual fee can feel like an excellent investment in convenience and benefits. For families where one member travels frequently while others don’t, the targeted use of authorized users can maximize the card’s value without overpaying for features no one will use.
