Many years ago I was a new hire on Reserve. I had time to waste, I called up Crew Scheduling and asked if I could stop by and introduce myself.
I did ... among the interesting things I learned was that they were able to look up the airport I commuted from and see how many other people commuted from there also (I suspect their program allowed them to look for how many people lived within X miles of ABC airport). Sometimes they need a replacement on short notice.
Can they still do that? I don't know but it would be an easy phone call before they start their daily routine.
