Hi all,
I am doing a Star Lite Ex-Australia (SYD-SFO-FRA-BLR/Ground/KTM-SIN-MEL)

When I get back home to SFO I will be about 1,000 miles short of Prem Exec on United so want to add a short round trip to the fare keeping the actual miles low to preserve my 26,000 mile total but to get two segments on UA for the 1,000 miles I need.

Is it possible for me to add a quick SFO-Monterrey, CA or Modesto to the Star Lite without breaking the "only once in each city" or do I need to do something like OAK-LA.

Can I avoid using the extra stop if I add the two segments within 24 hours of my arrival back at SFO (no fun at all!)

Thanks
