Yes, you can earn Delta SkyMiles on qualifying Hertz car rentals, and the earning rate is highly rewarding for frequent flyers in 2026. General SkyMiles members earn 4 miles for every $1 spent on the base rental rate. However, if you hold Delta Medallion® Status, your earnings increase significantly: Silver Medallions earn 5 miles, Gold members earn 6, Platinum members earn 7, and Diamond Medallion members earn 8 miles per $1 spent. Additionally, Gold, Platinum, and Diamond Medallion members are eligible for complimentary elite status in the Hertz Gold Plus Rewards® program, which provides benefits like car upgrades and the ability to skip the counter. To ensure you receive these miles, you must add your SkyMiles number to your Hertz profile or include it at the time of booking. It is also important to note that these miles are usually deposited within eight weeks after the rental is completed. For those who prefer to save money instead of earning miles, Delta also allows SkyMiles members to pay for their car rentals using miles through the Delta Cars portal.
