I'm new to the Qantas board and may have missed the answer to this (seemingly) simple question. Does QF allow you to rebook the same flights on the same days if by doing so you would save money? I booked our flights SYD- CNS in March 2008 this past May. The same flights are now available for more than A$100 less than what I originally paid. Can I cancel and rebook to get a refund of the difference?
