KLM meet and seat allows passengers traveling on the same airline the option to share the Facebook and Linkedin details when they check-in and select a seat. This allows others who have done the same to choose who they would like to "meet" on-board (the video below shows a business meeting but in my view this might as well be a hook up) and arrange to seat next to them.
Kinda spooky but an interesting thought.
