Delta has been on a roll this year, announcing major plans at CES 2025, which include innovations like an AI-powered “Delta Concierge” that provides personal, contextualized insights and experiences, helping customers optimize their travel journeys.

Delta is also launching a new onboard experience, with a cloud-based inflight entertainment system. The platform is inspired by the Delta Sync experience, which debuted in 2023 for SkyMiles members, providing access to customer-favorite brands and content, like YouTube.
