I want to travel to Europe in June 2019 but aren't ready (don't have the cash to book right now) and would like to take advantage of this but:
Method 1: Book a domestic flight and change it later
Looks like that wont work ...
"If you change or cancel your initial qualifying booking ... this bonus offer will not apply."
Method 2: Buy a voucher to use it later
Again, that may not work.
For example, if I buy a voucher now and book in January 2109 for a flight in June 2019 I haven't "redeemed for an eligible flight booking during the promotion period", but it is ambiguous. Does it mean the booking must be made between "12.01am (AEST) 9 August 2018 and 11.59pm (AEST) 14 August 2018" or the flight must be taken between "21 August 2018 and 8 August 2019".
Any suggestions?
