My goal is to reach the following cities between March 17 and April 11

Mex; SJU; HKG; ICN; SYD; EZE; BOG (All others city where you 'll see I stopover, could be eliminated if they create any conflict)

2 other requiriements: first city must be Mexico (March 17), and last city must be Bogota (stay between April 9 to April 11).

Checking one-world airlines schedules, I came with the following. I would appreciate your comments about if this itinerary qualifies for a RWT.
I mark with a small "x" the cities where I will be transfering/transit. The ones with an "(S)" is where I am stopping over.

JFK-xMIA-MEX(S)-xMIA-SJU(S)-xLAX-xHKG-xICN-HKG(S)-SYD(S)-xLHR-MAD(S)-xSCL-EZE(S)-xSCL-BOG(S)-xMIA-JFK

Some analysis I did:

6 segments in zone1 (JFK-MIA-MEX-MIA-SJU-LAX; and MIA-JFK at the end)

2 segments in Asia. Although HKG is touched twiced, only one is stopoever, the other one is transit. I think this is allowed when itinerary includes S.Pacific.

1 segment in Europe

3 segments in South America


Should I assume this is a Explorer w/4 zones w/approximatly 47,000 mileage, thus price in the US should be around $6,200 (before taxes, airports taxes, fees, etc) ?

Does the itinerary looks OK?

Thanks for your assistance!
