Air France has a $649 fare from San Francisco SFO to Ljubljana, Slovenia LJU airport. Air France is the operator of the flights and Delta is offering the low fare as DL codeshare flights on Delta.com. Fares at $689 to $700 round trip are widely available through Delta Airlines ticketing. This is the first time I recall seeing an airfare deal from California to Slovenia this past year.
Slovenia is the border country of northeast Italy and Ljubljana is the capital city. This is a city that existed during Roman times so many centuries of history to discover. Ljubljana, Slovenia is four hours by train to Venice, Italy.
Google Flights shows KLM/Adria Airlines flight options as low as $649, but these result in a fare that must be ticketed by phone. Adria Airlines is a Star Alliance airline. $688 through Delta.com was the lowest fare I found online.
Departure Dates: Low fares in the $600s are available for flights departing SFO from this week through April 2016.
Google Flights fare calendar March-April 2016 SFO-LJU shows most fares in mid-$600s. The lowest fare I found bookable online at Delta.com is $688.

There are overnight possibilities in Paris as seen in the itinerary above, although the flight arrival at 5:25pm and morning departure of 10:30am from CDG means in reality you have about enough time to see the city of light for a couple hours or have dinner and plan a one night hotel stay.
Sacre Coeur, Montmartre, Paris at night as seen on my Sep 2015 trip. The steps were filled with partiers drinking and gazing across the city from the hilltop in Paris. Someone nearby played ‘All Along the Watchtower’ on acoustic guitar. I had a good overnight in Paris at Montmartre.
San Francisco to Ljubljana is an interesting low fare deal to an uncommon and hard to spell destination in Slovenia. This fare in the upper $600s is significantly lower than any other airport in the area and another sign more low fares are coming for California to Europe routes this winter and spring.
If Paris, France or Venice, Italy is your real desire, Turkish Airlines has fares under $600 round trip SFO-VCE and SFO-CDG flying one-stop itineraries via Istanbul.
