July 2, 2026 | 2 min to read
FRANKLIN, Tenn. – As Americans gear up for one of the busiest travel weekends of the summer, Carl’s Jr. is issuing a playful challenge to road trippers everywhere to pass Jack – Jack in the Box – for a better burger option, one that’s hot, juicy and loaded with real flavor.
Starting June 23, Carl’s Jr. is rewarding those who prove their road trip loyalty by putting their flavor where their mouth is. My RewardsTM members who spot a Jack in the Box and keep driving to Carl’s Jr. will unlock a free Sourdough Star in their Carl’s Jr. app.
Claiming a free Sourdough Star is simple. From June 23–June 30, customers can claim their reward by visiting carlsjr.com/passonjack and uploading screenshot of a GPS route, or any other proof that they stayed the course and kept driving past a Jack in the Box to reach Carl’s Jr. Qualifying submissions receive a complimentary Sourdough Star, directly available in the Carl’s Jr. app, valid until July 76.
“When hunger strikes on a road trip, it’s tempting to pull over at the first burger joint you see,” said Paz Romero, vice president of brand marketing at Carl’s Jr. “This summer, we know our loyal fans and new customers are bound to drive by a Carl’s Jr., so we want to reward them for stopping at the best burger option on the road.”
Fresh off its return last month, the legendary Sourdough Star is back for a limited time, featuring a delectable charbroiled all-beef patty, two strips of cherrywood bacon, classic sauce, grilled onions, melted American cheese, lettuce, tomato, and mayonnaise on thickly sliced toasted sourdough bread. To complement the summer lineup, Carl’s Jr. also recently announced upgrades to Build Your Own Bag and introduced a new, thirst-quenching Triple Berry drink lineup.
