Apologies in Advance if this is the wrong place to be posting. Seeking some help in pricing a RTW. This would be for my Mum and so being a Senior, she'd prefer not too long transits and the likes . I had initally priced the below as 4 separate One - Way tickets. Prices given below. Was thinking, it would be good if she got some decent amount of miles for the flying ahead and then realized might be better to look at a RTW option from Star or One world.

MAA – YVR / Mar 20th / CX – $ 800 INR (One World)

YVR – MEL/ June 10th/ FJ – $ 820 (No alliance)

MEL – LLW/ Aug 30th/ QF, ET – $ 1,085 (One World)

LLW – MAA/ Sep 16th/ ET or AI – $500 (One World/ Star Alliance)

NET TOTAL : $3205


Am a novice to this world of RTW tickets and so any help/ pointers would be most appreciated.
