Following Singapore Airlines and American Airlines passengers’ privacy concerns over cameras spotted in seat-back entertainment displays, United Airlines and Delta have confirmed to BuzzFeed News that some of their screens also include camera lenses. The displays with cameras embedded are found in the airlines’ premium economy class, available on select international routes.

Both United and Delta said that the cameras were included by the manufacturer of the entertainment systems, Panasonic, and are not active. A United spokesperson told BuzzFeed News that cameras are “a standard feature that manufacturers of the system have included for possible future purposes such as video conferencing” and the airline has “no plans to use them in the future.”

While video conferencing is not available on United flights, the feature is currently in use on some Emirates flights with Panasonic entertainment systems aboard, for first-class fliers.

In a statement provided after publication, Panasonic Avionics Corporation said that it "will never activate any feature or functionality within an IFE system without explicit direction from an airline customer" and that "the cameras have simply been included to support potential future applications like seat-to-seat video conferencing."
