Yes, United Airlines has committed to a massive fleet-wide installation of seatback In-Flight Entertainment (IFE) screens as part of its "United Next" initiative. While many older United aircraft previously relied on "Personal Device Entertainment" (streaming to your own phone or tablet), the airline is currently retrofitting its entire mainline narrow-body fleet (Boeing 737s and Airbus A321s) with high-definition screens at every seat. By the end of 2026, the vast majority of United's domestic and international aircraft will feature these screens, which offer hundreds of movies, live TV, and games. These new systems also include Bluetooth connectivity, allowing passengers to use their own wireless headphones. Even on the few remaining older planes that lack seatback TVs, United provides free streaming content via their onboard Wi-Fi portal. However, for the modern 2026 traveler, the "United Next" cabin has made seatback screens the standard across all classes, including Economy, bringing them back in line with competitors like Delta who have long prioritized the "TV at every seat" experience.
