Yes, many modern commercial aircraft are equipped with cameras in the cabin, though their presence and use are strictly regulated for security and safety purposes rather than for snooping on passengers. Cameras are most commonly located outside the cockpit door to allow pilots to verify who is requesting entry, a security standard implemented globally after 9/11. Some airlines also have cameras in the bulkheads (the walls separating sections) so flight attendants can monitor the cabin during takeoff and landing when they are strapped into rear-facing jumpseats. While there was a brief controversy regarding "hidden" cameras in seat-back entertainment screens on some carriers like Singapore and Delta, these were generally part of the hardware provided by manufacturers and were not activated or used by the airlines. In 2026, camera integration is increasing to support AI-driven incident reporting and medical assistance.
