I took a few flights recently, and for the first time ever (for me), all passengers were told before departing that "taking photos or videos of other passengers or crew is not permitted unless you get permission from them". Seems like this is really being enforced, because on one flight an elderly passenger who took a photo of his partner also got other people in the frame and a crew member sat down with him to get him to delete the photo.
One flight was from South America to Spain with Air Europa; the other one a flight within Europe with Transavia. This is the first time in many years that I have encountered this.
Is this something new? Where is this coming from? New legislation?
