I don't know which airport you're talking about, but at BOG it was just one leg needed. Things can change, but when I went on the 757 to Bogota, the Captain and I had never been. The AQFO showed us the ropes on the way down from JFK, then deadheaded deviated and DHed back to ATL. The second time it was just the Captain who hadn't been, so the AQFO sat up front on the way down and DHed back with us the next day.

I can't see why the AQFO would let you go home with pay when he can be the one getting the good deal.
