That is a different issue altogether.
routinely cancels flights if they are "not full enough".
As I said I have seen THIS happen hundreds of times, used to be very common in the good old days.
If we had 2 flights going to the same place within an hour or two of each other, both with not many pax, they would just cancel one and put them all on the same flight.
Sometimes too, but not as often, they would combine flights to different destinations, like for example combining a BNE-ROK-MKY flight with a low pax load with a BNE-TSV flight with a low pax load and have the one flight BNE-ROK-MKY-TSV, although this was more complicated because of crew hours etc.
