Yes, you can absolutely use Bluetooth on a plane without needing to connect to or pay for the onboard Wi-Fi. Under 2026 FAA and EASA regulations, short-range Bluetooth devices (like wireless headphones, keyboards, or game controllers) are permitted at all stages of flight, provided your primary device is in Airplane Mode. When you enable Airplane Mode, it usually shuts off all radios, but you can manually re-enable Bluetooth (and Wi-Fi) immediately afterward. This allows you to listen to pre-downloaded music, watch movies on your tablet, or use a Bluetooth transmitter to connect your wireless earbuds to the seatback entertainment system. The two technologies are independent; Wi-Fi is for internet/intranet data transmission, while Bluetooth is a local point-to-point connection between your devices that does not interfere with the aircraft's critical navigation systems.
