Can anyone advise why is it that air fares, specifically Qantas, from Aust-UK/Europe are around $500 more return than UK/Europe-Aust return, using the same dates and flight numbers? My eldest daughter, who works in the UK, regularly gets flights from the UK return to Sydney for around $1300-$1500. Other airlines likewise have similar differences. The same applies if travelling Singapore-Sydney return as against Syd-Singapore return.
I have my own suspicions, but will keep them to myself for the moment, until other ideas or thoughts emerge.
