My total mileage is 66236 miles which will equal 99354 Q points. </font>
Just a very minor alteration to your calculations - remember that flights from US to the Caribbean are in Business Class and not 1st so on LAX-SXM-JFK at 1.25 Q points per mile rather than 1.5 count on about 1000 Q points less than you've calculated. Don't let things get too close to the wire!
If you're flying out of Sydney after Feb 28th QANTAS will have recommenced direct flights SYD-JFK. So why not do SYD-JFK-DFW-GRU. It will give you a good safety buffer.
