Rule 4(l) states:
Within Australia - only one nonstop/single plane service flight is permitted between the following points:
BME - BNE/MEL/SYD
DRW - CBR/MEL/SYD
KTA - BNE/MEL/SYD
PER - BNE/CBR/CNS/SYD/MEL
Does this mean that only one flight combination from
each of the four lines is permitted, or that only one combination from the
entire four lines is permitted?
