hi all!
i am new to this!been searching for a while but couldnt figure out.so, thought will start a new thread.
i am close to silver on ST.but can manage to go into silver if i go on SA for the rest of the year.can someone suggest if its good to continue with ST and get their silver....or go ahead and get silver in SA.i have never been an elite, so dont really know the benefits of being in the elite program.i dont travel much domestically....
so suggestions are welcome.TIA.

i am in NW worldperks in ST and US airways in SA.my destinations are mostly served by Northwest/klm and Lufthansa.
