Yes, Bluetooth is permitted and works perfectly on aircraft in 2026, provided your device is in "Airplane Mode." While the FAA and international aviation authorities once had strict bans on all wireless signals, modern regulations allow for "Short-Range Wireless" (including Bluetooth and Wi-Fi) throughout all phases of the flight, including takeoff and landing. Your Bluetooth headphones or controllers communicate directly with your device and do not interfere with the aircraft's sensitive navigation or communication systems, which operate on different frequencies. However, you should still keep the cellular "radio" (for calls and data) turned off unless the plane is equipped with an "onboard cellular" antenna, which is still rare. Most modern 2026 aircraft cabins are now optimized for Bluetooth, with many seatback entertainment systems allowing you to pair your own wireless noise-canceling headphones directly to the screen, eliminating the need for the traditional two-prong wired adapters.
