Delta Air Lines will remove fees for its in-flight entertainment by July 1, becoming the first U.S. airline to do so.

The move makes all in-flight entertainment free on Delta's dual-class airplanes, which make up nearly 90 percent of the airline's fleet. Not included are Delta's smaller 50-seat jets, which are not equipped with in-flight entertainment systems.

Atlanta-based Delta's in-flight entertainment includes movies, TV shows, music and live satellite TV available on seat-back screens on nearly 400 of its planes, or streaming on laptops, smartphones and tablets.

Delta previously charged fees for some of the entertainment, such as $6 for new release movies and $1 per episode of HBO shows.

The airline said its entertainment offerings will continue to include "recent box office hits" like "Hail, Caesar!" and "Batman v Superman: Dawn of Justice."

Delta said the move to make in-flight entertainment free is part of its "investments in the customer experience."
