Hi, RTW newbie here just about to embark on buying my first ticket (LONE4). I've checked it out using the OneWorld planner and all seems to be in order but I'm sure someone will be able to find a flaw in it somewhere...

SIN-(LHR-CDG)-(surface to MAD)-LIM-IPC-(LIM-LPB)-SCL-(SYD-BNE)-NOU-BNE-(HKG-XIY)-(HKG-SIN)

More importantly, what is the best way to get the lowest fare for this itinerary? Using the online tool necessitates putting in dates - I'd prefer buying an open-dated ticket as my travel dates are not fixed - and will cost me SGD7489 in total. I live in Australia (not in a big city, no access to good travel agents here unfortunately) but would rather depart from Asia.

Also, why do I keep seeing people using AA? Is there a benefit by ticketing through them - do they allow free date changes for example (QF says they can change dates for 'free' but will impose a service charge of AUD80 each time).

Thanks for clueing me in guys.
