UA/LH: SFO-LOS(Lagos,Nigeria): 4.4cpm: 878USD, 19.7k miles, same-day turnaround

Either fully UA-coded or partially LH-coded:

SFO-IAH-FRA-LOS-FRA-IAH-SFO

All books into UA/LH L, bookable on United. (I couldn't get United to price it out properly though, easiest way is via hipmunk.com, use ITA notation SFO:: IAH FRA to LOS:: FRA IAH, it will price it properly and give you a link to the itinerary on united.com)

You can also add SEA-SFO and SFO-SEA to the trip, making it 961USD for 4.6cpm and 21k miles.

Sample itinerary Feb 19-21, you leave SFO at 9am, arrive at LOS on the 20th at 5:40pm, leave LOS on the 20th at 11:40pm and you're back in SFO on the 21st at 6:05pm. All in a weekend and no hotel cost. I think it's available pretty much every Fri-Sun in February. (not sure if this link works: https://www.hipmunk.com/flights?utm_...8ec26c;group=2 )

Good find X: SFO. ^ FYI The SEA segments add at 8cpm (w/ elite 500mi min), so not really worth "adding"
