Given that most traffic into capital primary's are RPT with a known schedule; I'd ask why cant you?
That's pretty naive, Joe. Do you really expect multiple RPT aircraft could/would stick to their schedule plus or minus a couple of minutes so the flow would work with no slowdowns or re-sequencing?
a delaying vector. Kind of silly way to do it, but that's aussies for ya
Losing time in straight lines is better, fuel burn wise, than holding patterns. Nicer for the pax, too.
