Air Canada, Lufthansa, Swiss and United have ticket prices at $427 for San Francisco to Paris for travel departures January to mid-May and then again from mid-August. United Airlines nonstop flights are available on some dates. Many of the low fare August itineraries force an overnight in Zurich on the return with Swiss Air back to SFO.
Paris has been the low spot destination in Europe the past couple months as an alternative to flying to Scandinavia for cheap fares to Europe. These ticket prices are well below other cities in Europe for travel in mid-August, making Paris a cheap trip destination for the end of summer or a launch point for cheap flights to most any other place in Europe.
