10 Qantas domestic flights departing from Sydney were cancelled yesterday. Two possible reasons for that. They either didn't have enough serviceable aircraft, or their yield management planning went berserk. If it's the former, management have messed up - still flying plane beyond their used by date or a lack of personnel to fix them. If it's the latter, demand for flights has deteriorated at an amazing rate - an announcement should be made to the market. Which is it Geoff? The silence is deafening!
