Bluetooth is finally coming to airplane seatback entertainment systems

United Airlines may not always live up to its slogan of "Fly the friendly skies" — especially with ongoing incidents of passengers being removed from flights under questionable circumstances — but the company is on the verge of making air travel a lot friendlier for folks with wireless headphones. The company has just placed a massive order for 270 Boeing and Airbus planes that will have Bluetooth-enabled seatback entertainment systems for every seat.
