OR TO UA-SAO-YY-RIO*
becomes
LAX-UA-LAS-UA-DEN-UA-DTT/PIT-UA-CHI-UA-
NYC/EWR/PHL/CLT-UA-WAS/ORL/TPA-UA-MIA-UA-RIO*
Do I have to do WAS before MIA?
Yes. Otherwise, you would be backtracking. Also, just because there are many intermediate points on the routing, it doesn't mean you are allowed to transit all of those points. Your fare rules also determine the number of transfers allowed.
