Delta Air Lines now has seatback entertainment systems on 600 of its planes, meeting its year-end goal ahead of schedule.

“We continue to invest in seat-back screens, because customers continue to tell us they’re important,” said Tim Mapes, senior vice president and chief marketing officer, Delta Air Lines. “With seat-back screens, customers don’t have to choose between using their phones or watching a movie. Whether they want to work, relax, or a little bit of both — we want to give our customers the ability to choose and make the most of their time in flight.”

Delta has more entertainment than any airline in the world, with free options available to customers in all cabins through Delta Studio. The system has:

—More than 300 movies, including around 80 foreign film titles

—550 TV show episodes

—12 channels of live satellite TV on select flights

—More than 2,500 songs

—A selection of podcasts and games, like in-flight trivia

Customers also stream content from Delta Studio on personal devices.
