XL France has non-stop flights for $727 and $865 for travel on Mondays and Saturdays in May & June, SFO-CDG. Looks like you have to finish all travel by June 25 to get the sub $1000 fares, not all Monday-Saturday combos work, and the longest trip I could string together was 15 days. Some combos with longer stays (also returning in June) are $1049, still cheaper than the $1400 and up that most fares are running on this route. Book on Vayama. XL doesn’t have the greatest history (bankruptcy of one division), so if you’re squeamish buy trip insurance
