Definitive "Are bluetooth headphones allowed?" thread
 

Hi all,
I'm probably not the only person who has ordered an iPhone 7 and am now thinking about using bluetooth (or the new Apple W1 technology) headphones. Since one of the places I use headphones a lot is whilst I'm flying I thought I'd check that I am actually permitted to use them onboard with the airlines I tend to use. The results I got were very mixed.
The information wasn't that easy to get, so I thought a "master list" might be useful? Here are the ones I've checked and the responses I found / got:

BA - Allowed during cruise, but not during takeoff or landing
KLM - Not allowed at any point
LH - Not allowed at any point (they say they are reviewing this, but have been for 3 years)
SAS - Permitted - chat with agent online said "the use of bluetooth headphones is not restricted"

Please help to expand this thread with other airlines. Maybe someone with the right knowhow could put this into a nice table?

I made a Wiki post. Anyone can do so; I just happened to. Otherwise, nothing to add. :)

Does anyone know how TK takes this?

The above wiki post suggests what the airlines policy but some crews do not enforce it. I would use it but if requested by the crew to power off/not to use them, I comply.
