Some airlines make announcements, they are allowed on all airlines I have travelled on in the last 2yrs (when I started travelling a lot..) I mean I don’t think I can prove that literally every airline does allow Bluetooth headphones, but see previous comments where the FAA approved Bluetooth headphones for use in 2013, maybe you could provide a specific airline which does not allow Bluetooth headphones?
