Yes, passengers flying Delta First Class (as well as Delta One and Delta Premium Select) are automatically eligible for Delta Sky Priority benefits. This includes access to a dedicated Priority Check-In lane, which is often significantly shorter than the standard Main Cabin line. In 2026, Sky Priority also grants you expedited security access (where available), priority boarding (typically in the second or third boarding zone), and priority baggage handling, meaning your checked bags should be among the first to arrive on the carousel at your destination. This status is also extended to Delta SkyMiles Gold, Platinum, and Diamond Medallion members, as well as SkyTeam Elite Plus travelers, regardless of which cabin they are flying in. Even if you don't have elite status, the simple purchase of a First Class ticket ensures you bypass much of the standard airport congestion, providing a more streamlined "curb-to-gate" experience.
