Delta Air Lines announced plans to install new 4K HDR QLED screens in its commercial airplanes, so passengers can experience ultra high-definition entertainment at ultra-high altitudes.

The news came as part of Delta’s CES keynote at the Sphere in Las Vegas, where it also planned to celebrate its centennial with a musical performance by Lenny Kravitz. The airline announced a raft of new features for air travelers, including new partnerships with YouTube and Uber as well as a new AI-powered chatbot for customer service.

But the decision to add 4K screens to its airplanes is one that’s sure to tickle the fancy of any air traveler who’s ever balked at the middling quality of the current crop of seat-back displays.

Delta says it’s working with Thales Avionics, an in-flight technology company that is also helping to install high-definition screens in Emirates’ Airbus A350-900s. But don’t go looking for the new screens just yet: Delta says it won’t start delivering the upgrades in aircraft until 2026.

Who actually gets access to the screens, though, will answer the question of whether Delta sees this as technology for all passengers or just the ones in first class. A spokesperson for Delta did not immediately respond to questions about access.

Delta has also been testing out Bluetooth connectivity for its in-flight entertainment for several years and has even started quietly rolling it out to some planes, as discovered by a TikTok user. Now, the airline says it plans to offer Bluetooth “in all cabins so travelers can pair their personal wireless devices” — though it didn’t offer any specifics beyond that.

Delta’s in-flight entertainment will also feature “an advanced recommendation engine” tailored to each passenger’s unique taste. Again, we’re lacking details about what’s powering this engine and how it will know your particular taste. But in late 2025, we’re getting improved “connectivity” through a partnership with Wi-Fi provider Hughes, which replaced Intelsat in 2023. Delta says this will allow for “multi-network connectivity” for more “reliable” and “stable” in-flight internet.

That surely will help when streaming YouTube, which SkyMiles members will be able to do ad-free, thanks to the platform’s new partnership with Delta. And a new “Do Not Disturb” mode for their seat-back screen will ensure passengers can sleep without disturbance.

Delta is revamping its app to include an AI-powered “Concierge” chatbot as well as a “multi-modal” feature that will include Uber and, eventually, air taxis from Joby.

The Concierge feature will use the traveler’s location and arrival and departure information to suggest more efficient routes and will notify users about upcoming passport expirations or visa requirements. And “in the years to come,” Delta says the feature will be able to make more specific recommendations around packing and weather planning.

Delta is also offering SkyMiles customers the ability to link their Uber account to earn miles and other perks. These include:

SkyMiles Members can earn 1 mile per dollar spent on UberX rides to and from airports, 2 miles per dollar on premium rides and 3 miles per dollar on Uber Reserve rides. Plus, 1 mile per dollar spent on eligible restaurant and grocery orders.

And lastly, Delta says it’s working with Airbus to design more fuel-efficient airplanes. Delta has said its goal is for sustainable aviation fuel to make up at least 95 percent of its fuel consumption by 2050. But achieving net-zero emissions will be a tall task for an airline and will require rethinking every part of the business.

Now, Delta says it will work with Airbus to scale the use of sustainable aviation fuel, which is mostly biofuels made from plant or animal material. And the two companies will collaborate on hydrogen-powered flight projects as well as new designs, like more fuel-efficient wings or new formations to drive “wake energy retrieval,” Delta says.
