UA SFO-SJU (through IAD or EWR or IAH) $331-$340 A/I

Hello Everyone!
Just FYI, I found this reasonable R/T SFO-SJU April through June.
Mostly during the week. I booked a couple of red-eye/same day turnaround. (fly the redeye to EWR or IAD then IAD-SJU-IAD-SFO the next day)
Fares were around $337 round trip including taxes. Roughly around $.046 CPM if done through IAD/or EWR.
Fare Basis: SXA7SNN
I routed through IAD mostly since EWR is notorious for delays the last time I did this.
Enjoy!
