While other CEOs of Southwest and American Airlines questioned current mask mandates in front of Congress, Delta CFO Dan Janki in his exclusive interview with Cheddar, was more cautious about doing away with the safety measure. "We're right now at the beginning of another wave," he said. "This is probably not the time to change mask policy." Janki also discussed his airline's future in loyalty program pricing, international travel, meal services, and stock pricing.
