One SAT tip: If www.airoutlet.com fares really do earn miles, as Sheryl has reported from communication with them (I'm not doubting, just no one has actually flown one to know), then you can get SAT-PHX through AirOutlet for $161.50, routing through both MEM and MSP, depending on the dates. That's 5,200 status miles, and you can bank NW miles into CO's program. I'm eyeing this myself as a possible mileage run from PHX.
