slightly higher fare ($190 a/i) for next Januaray. Lots of availability.
Alternative routing gets you more miles:
PHL-SFO-SMF-SFO-PHL
gets you 5214 miles if you take the SFO-SMF-SFO flights (3.6cpm)
if you don't take the short flights and just take PHL-SFO-PHL, then you get 5042 miles (3.7cpm)
When will UA bring the 500-minimum rule back
