Yes, holding an American Express Platinum Card provides you with a specific elite status through the Avis Preferred loyalty program. Specifically, Amex Platinum cardholders are eligible to enroll in Avis Preferred Plus (or sometimes marketed as the "Avis Preferred" elite tier depending on the region). This status grants several premium benefits, including complimentary one-car-class upgrades (subject to availability), accelerated reward point earning, and a dedicated customer service line. One of the most valued perks is the ability to bypass the rental counter at many major airports, allowing you to go straight to your car. To activate these benefits, you must manually enroll through the "Benefits" section of your American Express online account; the status is not automatically applied just by owning the card.
