In 2026, the American Express Platinum Card® is widely considered the best choice for car rentals, primarily because of its Premium Car Rental Protection and elite status perks. While most Amex cards offer "Secondary" insurance (which only kicks in after your personal car insurance), Platinum cardholders can enroll in the "Premium" program for a flat fee (roughly $20–$25 per rental) that provides Primary coverage—meaning you don't even have to file a claim with your own insurance company if you have an accident. Additionally, the Platinum Card gives you automatic Elite Status with Hertz (Gold Plus Rewards President's Circle), Avis (Preferred), and National (Emerald Club Executive), which grants you free upgrades and the ability to skip the counter. In 2026, the American Express® Gold Card is also a strong contender for its high points-earning on travel, but it lacks the "bypass the line" status of the Platinum. If you rent cars frequently, the time saved by walking straight to your car at the airport and the "peace of mind" from the primary insurance makes the Platinum Card's high annual fee a high-value investment.
