So I have been stashing points for a year or so and am really interested in trying to cross off the final 4 continents to visit. I want to redeem flights in J. Is there a routing that is most efficient? I don’t have to do all at once but if there’s an efficient way to knock off 2 at once - that what I’m interested in.


My stock of points is:
SQ - 264,000
AS - 158,000
UR - 270,000
Avios - 140,000

Africa
South America
Antarctica
Australia / Oceana

Thanks for any tips!
