I'm not sure everyone understands the Amflight program. First of all, it's not an Amflight program, it's Eagle Jet International. EJI pays Amflight a fee for the right seaters and the Amflight PIC's get a small pay override. The right seaters are NOT required crewmembers, and can be bumped for freight.
You can question the value of the time, or even the FAA "loophole" that allows it to be logged, but it's not the same PFT/PFJ that Gulfstream is doing.
In my view, if you're not a required crewmember, then you're not taking anyones job.
