No set schedules so it is hard to get where you "want" but for the most part the 767-200 in MIA does MROC/SJO, MGGT/GUA, and MPTO/PTY throughout the week. The 767-300 in MIA can do most anything in South America. MIA flights usually start in the Lan Cargo building.

It will be hard to ride on the Middle East stuff since the flights basically only go to AirForce Bases in Afghanistan and the planes are usually full with a L/M, MX and IRO plus at least one or two DHL Middle East employees.
