This thread is a little deceiving, because at least some of it doesn't really have anything to do with MPC / Asia Miles and the standby list everyone on here would consider relevant.

1.) "1" has nothing to do with cash tickets you'd be buying...it refers to a typical form of staff ID ticket, and is a normal priority for staff. Again, this has nothing to do with standby as everyone on this forum thinks about it.
2.) Staff only
3.) Unsure, because I don't know what list you actually saw.
4.) Some Swire staff, pilots and individuals from other airlines / industry sources can also standby for F.
5.) Unsure.
