I was just there 7/5-7/9 and wish someone had thought about this earlier. However I did meet some AOK FTers in both SFO(6/26-DGOLDS) & SAN(7/1-CAPTAINMIKE).
Count me in for the future, but I show up more during Seattle's delightful winter.
My usual routes are either MKE-SFO-SEA-PHX-MKE or MKE-PHX-SEA-SFO-MKE, obviously designed to maximize NWA miles through a combo of NWA & Alaska flights. This routing, open jaws on NWA -MKE/PHX & SFO/MKE and Alaska - PHX/SEA/SFO usually costs less than a MKE/SEA roundtrip.
