I see that AF 82 CDG-SFO (772) has BEST J on Wednesdays and Fridays in the summer schedule...
I was really tempted to select that option when I bought my ticket last night, but since its 6 months out and there could be equipment changes, I decided to go for KL 789 both ways...think I made the right call? Would have loved to try both AF and KL reverse herringbone but a bit too much uncertainty as SFO seems to be an 'unstable' destination when it comes to BEST/NEV4...
