Hi, I am so new to this that I have only just worked out what DONE stands for! I would really appreciate some tips here please.

We are looking at RTW tickets for 2 x adults plus 1 infant and 1 child, leaving Sydney round March/April 2012, spending most time in UK but interested in other destinations, as yet flexible (though relatively child-friendly).

1. I can see sales on buying direct flights to europe (inc stopovers) but can anyone point me the way of good prices/deals etc for RTW/DONE?

2. Also, there is currently a voucher deal on living social here in Oz where $99 gets $1000 off business class on BA web or phone. Is there any way this could be used to buy a DONE or will it only be for direct flights?

3. I was thinking maybe I could use the voucher to get better deals on adult fares and use QF points to buy child/infant seats? Is that even possible?

thanks!
