This could lead to immense awkwardness if used for purposes to meet another of your preferred gender for dating purposes. Given that a photo is involved, and I assume you can decline a seating request - you will more than likely run into the requesting person waiting for boarding. However there are some types of people who have plenty of confidence in this (those who post publicly on the net already with their RealLife profiles) who may be open enough to decline/accept declined seating requests and not be bothered by the results. Personally, given that being on a plane is an enclosed space, I would be loathe to offer my public profile as 'traveling alone' to other passengers. But I do find it interesting that, knowing these social effects, KLM went ahead with this anyway and I have high respect for Dutch considerations in these matters. It must have tested well.
