Air Canada, along with a few other Star Alliance airlines (including SWISS International Air Lines and Lufthansa), are putting Europe on sale and one of the best deals active right now is SFO to Rome, Italty. Flights start at $258 round-trip, after taxes with open availability (note that the lowest prices are for travel in February and March 2019, but great deals can be found through May 2019.
Also, this deal is for new, “basic” economy type fares, where you’ll have to pay to check luggage (even if you have Star Alliance Gold or above status) and you can’t select a seat without paying. You do, however, collect full Premier Qualifying Miles from United (I booked this trip and will be accruing 13,016 miles).
There are similarly low fares across the country to Europe right now from a ton of different airports (including EWR, LAX, and Houston and flying to Paris, Milan, and London).
