Can't find the answer on Google! If these headphones are Bluetooth will and the jack is 3.5 mm will the jack fit plane jack for the in flight movies?
Did you have a link? Most flights I've been on recently as in last 5 years now use a single 3.5mm jack plug as opposed to the three pin triangular thing KLM used for many years, the question is do the Bluetooth headphones have a cable as well? My kit, the dongle is a bluetooth transmitter you plug it into the socket in your seat it'll transmit the audio coming through the jack to any bluetooth headphones you own. In my case I have these small over ear headphones because I often fall asleep watching the movies but you can still hear people around you too, you can also see the two pin adapter that is needed for some planes as well I have a few of those as I have more than one headphone set. The two pin adapter in the picture fits across two of the three pins in those triangular sockets I was talking about.

They should be fine with the supplied cable but get yourself one of those 2 pin adapters as well just to be sure that you can fit the particular socket in whatever plane you end up in.
