Lets see, Yes lets call out a crew member from the AKL or CHC base. Lets assume there is a crew member on standby at the airport and not on call at home where they would need the standard 2hrs notice. Its about 1130hrs local time, the next flt from CHC or AKL on any carrier isn't until about 1530hrs arriving into MEL about 1730hrs local time. So now the flt has been delayed at least 8hrs. And as this a/c would've been due to operate other flts when arriving into CHC at least another 180pax have delayed, which would probably force ops to xxl the next sector to recover the schedule. Oh yes doesn't this seem like a sensible decision to make rather than offload 13 pax and have it delayed 60-90mins and not have to inconvenience another 180pax, give me a break do the math!!!!!
