Well, the 24 000 pounds sounds alright, I guess it's comparable to what you can earn at LHR Eurofleet, maybe a little less, but you can earn way more at LHR World Wide, which I assume is the same type of flying QF UK will be doing. Is it better than what you can earn at QF Australia???
The 18 000 pounds I think would be a little hard to live on though, but at least it's guarenteed, and not based on allowences and what trips you get.
None the less, I still think this LHR base sucks!
One more question...If you join QF UK, are there any chances of being transfered to an Australian base?
