Hello all,

I am flying LAX-FRA on the 19th and FRA-LAX on the 23rd, I am really excited for the trip as its for work but a fun work trip. I should have a little over 30K in the bank by the time I get to FRA and my trip there is not as important on the way back ( I have to work on the 24th) for comfort. I am booked on a S Fare and was wondering if I could use miles to upgrade into business class for the FRA-SFO leg of my trip home? Any hope? And also any expectation of what it will cost in $$$ and/or miles? Thanks a lot, I am pretty new to this site but I hope to learn a lot here.

Thanks.
