hi - i never travel on miles, usually give them to family, but i need to book the following iten in nov/dev:

kin-nyc
nyc-yyz
yyz-stl
stl-kin

with roughly 1-2 week stopover in NYC,YYZ and STL

on AA it books each leg seperately- is there a way to maximize mileage with stopovers, and how to do this?

thanx for any help
