No, Delta Comfort+ (or equivalent "Comfort Class" tiers) is generally not included in Sky Priority in 2026. Sky Priority is a premier suite of services—including priority check-in, security, and baggage handling—reserved exclusively for passengers in First Class, Delta One, or Premium Select, as well as SkyTeam Elite Plus members (Diamond, Platinum, and Gold Medallion). While Comfort+ passengers do receive Priority Boarding (usually boarding in "Zone 5" or just after Sky Priority), they do not get the expedited check-in or "yellow-tagged" priority luggage service that defines the Sky Priority experience. For a 2026 traveler, the "Comfort" ticket is a high-value choice for extra legroom and free drinks, but it does not grant the "fast-track" airport benefits unless the passenger also holds high-tier elite status with Delta or a SkyTeam partner.
