I was scheduled to dead head back home on an overbooked flight. A sailor who had been on leave was going to get bumped and eventually miss ship's movement (for those of you who don't know, that is like a missed trip times 1000). I got the CA to hold the flight a few minutes while I coordinated with crew sked to put me on a later flight. The gate agent said he couldn't put the sailor on because there were other pax ahead of him. I talked to the pax and convinced them to let the sailor go to the front of the line. I called his folks that evening, they said he made it and thanked me.
