Then you better go play golf with him and the scheduler(s).

They are amazingly capable at manipulating short calls to sniper shot trips in scheduling. It takes a coordinated effort among willing participants. I also strongly suspect that they hold trips out of open time, but then again, I've gotten lucky and sniper shot some over the phone.

The other issue with the 73N is that the double all nighters to S and Central America burn up a lot of TAFB without generating much block or credit. They balance those to avoid pilots going over 70 hrs on reserve.
