Rolling out in April, United Airlines will offer a special personal device entertainment system on-board select aircraft for people using the iPhone and iPad, running iOS 7.

Customers will be able to choose from more than 150 movies, and close to 200 TV shows, which they can access free of charge.

“Most planes will be equipped with the new system very soon, and we’ll have it installed on most domestic aircraft by the end of 2014,” United says. “We’ll begin on Airbus A319, Airbus A320, Boeing 747-400 and select 777-200 aircraft, followed by additional fleets. In the end, all United-operated flights will have some form of entertainment.
