I am not prone to hyperbole in Loyalty Traveler airfare postings. Good deals come around all the time, but ticket prices under $500 for San Francisco to Europe in July are the kinds of fare deals rarely seen in the past 15 years.
Star Alliance has Paris, Copenhagen, Oslo and Stockholm on sale from $489 on Momondo.com searches or priced as low as $527 directly through united.com for travel June, July and August.
London is on sale for $570 to $610 with Virgin Atlantic, SkyTeam and Star Alliance. Oneworld tickets are under $600 to London through Momondo searches.
July ticket prices are normally $900 or more to most cities as is seen in a Google Flights Map for SFO to Europe.

Once you have found low fares on Google Flights, then go to Momondo.com to check for even lower fares.
