I don't consider myself a real "frequent" frequent flyer, but I've managed to do fairly well:

A couple of one-way segments in the US on NW
Two coach MIA - PEK, also on NW
Three coach SCL - SAN, on UA
A few inner-Chile trips for my wife, courtesy of UA
One SCL - LAX, this time on LA
Four LIM - SYD, in business on UA

Next up on my agenda are India, Hong Kong, New Zealand or Melbourne. We'll see what happens...
