1. Introduction

The American Express Platinum Card is one of the most prestigious credit cards available, offering a suite of luxury travel benefits and rewards that cater to high-net-worth individuals and frequent travelers. With the option to add additional cardholders, the benefits can be extended to family members, employees, or business partners. However, like any premium service, there are costs and considerations involved.

In this article, we’ll dive deep into the American Express Platinum additional card fee, explain the benefits available to additional cardholders, and help you determine whether adding one or more individuals to your account is a good value for your financial situation.

2. What Is the American Express Platinum Card?

The American Express Platinum Card is a high-end credit card designed for those who seek premium benefits and rewards. Known for its luxury offerings, this card caters to frequent travelers, offering perks such as access to airport lounges, elite hotel status, and exclusive concierge services. The card has an annual fee that can be quite high, but the extensive rewards and benefits more than justify the cost for many cardholders.

Some of the highlights of the American Express Platinum Card include:

• Access to over 1,300 airport lounges worldwide through the Centurion Lounge and Priority Pass network
• $200 in airline fee credits annually
• 5x Membership Rewards points on flights booked directly with airlines or on amextravel.com
• Global Lounge Collection access
• Comprehensive travel insurance benefits

The Platinum Card is also notable for offering an extensive membership rewards program, allowing you to earn points that can be redeemed for a wide range of rewards, including travel, shopping, and statement credits.

3. What Is an Additional Cardholder?

An additional cardholder, sometimes called an "authorized user," is an individual who is added to the primary cardholder’s account. While they receive a separate card with their own name on it, they will share the account's credit limit and benefit from the primary cardholder's rewards and perks.

For those who hold the American Express Platinum Card, adding an additional cardholder allows the individual to enjoy many of the same premium benefits. These benefits include lounge access, travel credits, and exclusive concierge services, but they do come with a cost, which we will explore in the following sections.

4. How Much Does It Cost to Add an Additional Cardholder?

The cost of adding an additional cardholder to your American Express Platinum Card depends on the annual fee associated with the card. As of now, the fee to add an additional cardholder is $175 per year for each individual you add to your account.

This fee may seem high, but it is important to understand that it allows the additional cardholder to enjoy all the benefits of the Platinum Card. If you are adding multiple additional cardholders, the costs can add up quickly, so it’s important to evaluate whether the benefits justify the price.

Annual Fee Breakdown:

• Primary Cardholder Fee: $695 (as of 2025)
• Additional Cardholder Fee: $175 per person, per year

While the annual fee is significant, many cardholders find that the rewards and benefits of adding an additional cardholder far outweigh the cost, especially for those who travel frequently or have family members who can benefit from the perks.

5. Fee Breakdown: American Express Platinum Additional Card Fee

Here’s a detailed breakdown of the American Express Platinum Additional Card Fee:

• $175 per Additional Cardholder: This annual fee is charged for each individual added to your account. The additional cardholder receives a personalized card and enjoys most of the benefits that come with the Platinum Card.
• No Additional Spending Limit: The additional cardholder’s spending is linked to the primary cardholder’s account. This means the cardholder’s spending does not have its own separate credit limit. However, the primary cardholder is ultimately responsible for ensuring that payments are made on time.
• Shared Membership Rewards Points: All Membership Rewards points earned through the additional cardholder’s spending are credited to the primary cardholder’s account, making it easy to pool points for greater rewards.
• No Additional Eligibility Criteria: The additional cardholder must be at least 18 years old (or 21 in certain states) and cannot have a negative credit history with American Express.

While the $175 fee is charged yearly, there are ways to offset the cost through the various travel benefits and rewards that come with having multiple cardholders. For families, the ability to share benefits across multiple members can be especially valuable.

6. Benefits of Adding an Additional Cardholder

Adding an additional cardholder to your American Express Platinum Card can provide a range of benefits. The person added to the account will gain access to many of the same perks that you, as the primary cardholder, enjoy. Here are some of the top benefits:

6.1 Access to Airport Lounges

One of the most popular benefits of the American Express Platinum Card is access to the Centurion Lounges and Priority Pass lounges. As an additional cardholder, you will be able to enjoy the same lounge access as the primary cardholder.

• Centurion Lounges: These are American Express’s exclusive airport lounges located in major airports worldwide. They offer comfortable seating, premium food and beverages, business services, and more.
• Priority Pass: Additional cardholders also have access to over 1,300 lounges globally via the Priority Pass program, providing them with a quiet place to relax before their flights.

This benefit alone can make the additional card fee worth it for frequent travelers.

6.2 Membership Rewards Points

The Membership Rewards program is one of the cornerstones of the American Express Platinum Card, and additional cardholders can also earn these valuable points. All points earned by the additional cardholder are credited to the primary cardholder’s account, so you can accumulate rewards quickly when multiple cardholders are spending on the card.

Points can be redeemed for travel, shopping, and even transferred to airline and hotel partners for significant value.

6.3 Global Concierge Service

Another premium perk of the American Express Platinum Card is access to the Global Concierge Service, which provides cardholders with personalized assistance for a variety of requests, from booking travel and securing hard-to-get restaurant reservations to organizing exclusive events.

Additional cardholders have access to this same concierge service, making it easier for your family members or business partners to receive personalized support while traveling or managing their daily activities.

6.4 Premium Travel Benefits

Both the primary cardholder and additional cardholders receive premium travel benefits, such as:

• Elite Hotel Status: Gain automatic Gold status with programs like Marriott Bonvoy, Hilton Honors, and Radisson Rewards, offering room upgrades, late checkouts, and bonus points on stays.
• Hotel Benefits: Enjoy Room Upgrades, Daily Breakfast, and Early Check-In / Late Check-Out when booking through American Express Fine Hotels & Resorts.
• Travel Insurance: Comprehensive travel insurance covers things like trip cancellations, delays, lost baggage, and even medical emergencies while traveling.

Having additional cardholders who also receive these benefits can make trips even more rewarding.

6.5 Exclusive Events and Offers

American Express often provides access to exclusive events such as concerts, private sales, and VIP experiences. Additional cardholders can also gain access to these perks, which can enhance your lifestyle and travel experiences.

7. How to Add an Additional Cardholder

Adding an additional cardholder to your American Express Platinum account is straightforward. Here’s how you can do it:

1. Log into Your American Express Account: Access your online account through the American Express website or mobile app.
2. Navigate to the “Additional Cardholders” Section: In the account settings or "Services" section, you will find an option to add additional cardholders.
3. Enter the Additional Cardholder’s Information: Provide the necessary information about the person you’d like to add, including their full name, address, and contact details.
4. Review and Submit: Once you have entered all the required information, review the details and submit the request.
5. Wait for Approval: American Express will review the request, and once approved, the additional cardholder will receive their own card with the same benefits.

8. Conditions and Limitations

While the American Express Platinum Card offers a variety of perks, it’s important to be aware of any limitations:

• Credit Responsibility: The primary cardholder is responsible for all charges made by additional cardholders.
• Age Limit: The additional cardholder must be at least 18 years old (or 21 years old in some states).
• Geographic Restrictions: Some benefits, such as lounge access, may have geographic limitations, so check for any region-specific rules before adding a cardholder.
• Additional Fees: If the additional cardholder is using the card for purchases abroad, foreign transaction fees may apply depending on your specific card agreement.

9. Is the Additional Cardholder Fee Worth It?

For frequent travelers or those looking to extend luxury benefits to family members or colleagues, the American Express Platinum additional card fee can be worth the cost. The ability to share benefits like lounge access, hotel status, and concierge services can significantly enhance the value of the card.

However, for those who don’t travel frequently or don’t need the additional perks, the fee might not be justified. It’s important to weigh the costs against the value you expect to receive from the cardholder’s usage and benefits.

10. Alternatives to Adding an Additional Cardholder

If the $175 additional cardholder fee seems too high, there are alternative ways to gain similar benefits:

• Business Platinum Card: This card comes with many of the same travel benefits, and you can add employees as additional cardholders at no additional cost.
• Additional Cards on Other Rewards Programs: Some credit cards allow you to add authorized users for free or at a lower cost while still offering access to rewards and travel perks.

11. Conclusion

The American Express Platinum Card is a powerhouse in the credit card world, offering a vast array of luxury benefits and travel perks. Adding an additional cardholder to your account comes with a fee of $175 per person per year but provides substantial benefits, such as shared rewards, lounge access, and premium travel perks.

Before deciding to add an additional cardholder, carefully assess the value of these benefits based on your needs and lifestyle. For those who travel often or want to provide family members with high-end privileges, the additional cardholder option may be well worth the investment.

By understanding both the fees and the benefits, you can maximize your American Express Platinum experience and enjoy unparalleled service and rewards.
