Ok, I now have an amended booking, and I have reduced the amount of flights due to it becoming to difficult, and increased the amount of days staying in locations. I have had to be as restrictive on dates, as I could be taking up a position in Doha in late Aug or early Sept. Details are as follows:

SYD>SCL (via AKL) QF (L)
SCL>MAD IB (L)
MAD>LHR BA (L)
LHR>SYD (via BKK) QF (L)

So now the question is, 'which' program should I join? Just yesterday, I took up the offer of free QFF with the main supermarket I shop at which is linked to my fuel card, but this doesn't necessarily mean I should take up the QFF for this trip...

Thanks in advance!!
