This is all good to know, thanks! I'm leaning toward this group of flights then - gets us into CPH a bit later in the afternoon than I'd like, but prefer it rather than flying air canada. Do you guys typically book through Air France or KLM (or even Delta)? I'll likely just transfer points over from Chase since this combo of flights doesn't even show up in the Chase Rewards portal for whatever reason.
SFO > AMS > CPH via KLM
CDG > SFO via Air France


Actually - looks like there's some United/Swiss flights too, how's that compare to the KLM/AF combo? There would be 1 hr 55 min layover in ZRH, does that seem feasible?
