Meet the people on your flight

Love the idea. This might would work better if you could add in your connections on Linked In/FB/Foursquare to see who's taking the same flight as well going to SXSW or a major tourist spot like Thailand. Otherwise not sure this would work. without critical mass right off the bat.
I feel like this concept has been tried a couple times and has failed to get adoption. I'd love to give it a go once it's up and running on iOS and hopefully this rendition will stick.
This feels like a bit of a long shot, if you multiply the chances of knowing anyone on the same flight by the chances of both having the app installed. Zero utility until everyone is using it?
appreciate the effort, guessing the actual use case is most people relish privacy on their flights
