I am having a bit of a dilemma... I need to book a flight from OOL to SYD this week and can get cheap flights on Jet*, or I could book on QF in a TP earning class and get three lots of 12k bonus as have registered the family for the OW promotion.

The thing is this would cost around £300 more. I know that it would cost over £600 to buy them from BA but it just sits awkwardly with me to pay so much more and sit in Y anyway...

So what would you do?
