I know I posted this before but I can't find it, so here it goes again.
Everytime I pull into an airport and see what other carrriers are I always wonder if some friends are at the hotel or in town. It can be so random that you can be staying in the adjacent room to a good friend and never know it. So a guy from SKYW made a website called
http://www.pilotcrossings.com It allows you to upload your trip schedule and alerts you if you are going to cross paths with anyone you know.
So this is the perpetual meet n' greet invitation. I'm always up for meeting up with anyone so sign up and invite your friends.
